Complete Features

These features were completed when this image was assembled

Epic Goal

  • Complete the implementation for AWS STS, including support and documentation.

Why is this important?

  • Many customers want to follow best security practices for handling credentials.
  • This is the way recommended by AWS. 
  • Customer interest: EMEA, AMER

Acceptance Criteria

  • CI - MUST be running successfully with tests automated
  • Release Technical Enablement - Provide necessary release enablement details and documents.

Dependencies (internal and external)

Open questions:

  1. Will this cover existing OCP deployments or only new OCP deployments?
  2. Is there a migration path for existing customers to start using AWS STS?
  3. Are there considerations that apply to Operators so they can work with limited privilege credentials?

The tool should be able to upload an OpenID Connect (OIDC) configuration to an S3 bucket, and create an AWS IAM Identity Provider that trusts identities from the OIDC provider. It should take infra name as input so that user can identify all the resources created in AWS. Make sure that resources created in AWS are tagged appropriately.

Sample command with existing key pair:

tool-name create identity-provider <infra-name> --public-key ./path/to/public/key

 

Ensure the Identity Provider includes audience config for both the in-cluster components ('openshift') and the pod-identity-webhook ('sts.amazonaws.com').

Epic Goal

  • Support running the image registry services in single-node OpenShift configurations for production use in edge computing use cases.

Why is this important?

  • Some bare metal edge customers, especially in the telco market, want to use kubernetes at physically remote sites with minimal hardware.

Scenarios

  1. As a user, I want to deploy a fully supported instance of OpenShift on a single node.

Acceptance Criteria

  • CI - MUST be running successfully with tests automated
  • Release Technical Enablement - Provide necessary release enablement details and documents.

As a OpenShift administrator
I want the registry operator to use topology mode from Infrastructure (HighAvailable = 2 replicas, SingleReplica = 1 replica)
so that it the operator is not spending resources for high-availability purpose when it's not needed.

AWS 1 replica 2 replicas
Azure 1 replica 2 replicas
GCP 1 replica 2 replicas
OpenStack (swift) 1 replica 2 replicas
OpenStack (cinder) 1 replica 1 replica (PVC)
oVirt 1 replica 1 replica (PVC)
bare metal Removed Removed
vSphere Removed Removed

 

Epic Goal

  • Support running console in single-node OpenShift configurations for production use in edge computing use cases.
  • Support disabling the console entirely in some of these configurations to reduce overhead in constrained environments.

Why is this important?

  • Some bare metal edge customers, especially in the telco market, want to use kubernetes at physically remote sites with minimal hardware.

https://github.com/openshift/api/pull/827

The console operator will need to support single-node clusters.

We have a console deployment and downloads deployment. Each will to be updated so that there's only a single replica when high availability mode is disabled in the Infrastructure config. We should also remove the anti-affinity rule in the console deployment that tries to spread console pods across nodes.

The downloads deployment is currently a static manifest. That likely needs to be created by the console operator instead going forward.

Acceptance Criteria:

  • Console operator deploys console with 1 replica and no anti-affinity rules when not in high availability mode
  • Console operator deploys the downloads deployment with 1 replica when not in high availability mode
  • The console and downloads deployments do not change when in high availability mode
  • The feature is well-covered by tests

Feature Overview

Openshift Sandboxed Containers provide the ability to add an additional layer of isolation through virtualization for many workloads. The main way to enable the use of katacontainers on an Openshift Cluster is by first installing the Operator (for more information about operator enablement check [1]).

Once the feature is enabled on the cluster, it just a matter of a one-liner YAML modification on the pod/deployment level to run the workload using katacontianers. That might sound easy for some, but for others who don't care about YAML they might want more abstractions on how to use katacontainers for their workloads.

This feature covers all the efforts required to integrate and present Kata in Openshift UI (console) to cater to all user personas.

Background, and strategic fit

To enable for users to adopt Kata as a runtime, it is important to make it easy to use. Adding hook-points in the UI with ease-of-use as a goal in mind is one way to bring in more users.

Goal(s)

The main goal of this feature is to make sure that:

  1. It is easy for users to find out how to use/enable Openshift Sandboxed Containers on their clusters (e.g., Getting started guide in the UI).
  2. Cluster-admins are able to differentiate between normal pods and Kata pods.
  3. Developers (application, CNF, ...) have an easy way to create Katacontiners (without peeking at YAMLs)
  4. Application End-users are able to collectively activate kata on their app packages/content (e.g., Helm, odo,...)

Documentation Considerations

Questions to be addressed:

  • What educational or reference material (docs) is required to support this product feature? For users/admins? Other functions (security officers, etc)?
  • Does this feature have doc impact?
  • New Content, Updates to existing content, Release Note, or No Doc Impact
  • If unsure and no Technical Writer is available, please contact Content Strategy.
  • What concepts do customers need to understand to be successful in [action]?
  • How do we expect customers will use the feature? For what purpose(s)?
  • What reference material might a customer want/need to complete [action]?
  • Is there source material that can be used as a reference for the Technical Writer in writing the content? If yes, please link if available.
  • What is the doc impact (New Content, Updates to existing content, or Release Note)?

Goal

The grand goal is to improve the usability of Kata from Openshift UI. This EPIC aims to cover only a subset that would help:

  • Make it easy to differentiate between native cluster runtime (e.g., runC) and kata.
  • Enable Kata as a runtime without modifying YAMLs.

To use a different runtime e.g., Kata, the "runtimeClassName" will be set to the desired low-level runtime. Also please see [1]

"RuntimeClassName refers to a RuntimeClass object in the node.k8s.io group, which should be used to run this pod. If no RuntimeClass resource matches the named class, the pod will not be run. If unset or empty, the "legacy" RuntimeClass will be used, which is an implicit class with an empty definition that uses the default runtime handler. More info: https://git.k8s.io/enhancements/keps/sig-node/runtime-class.md This is a beta feature as of Kubernetes v1.14.." 

 

Pod-Runtimeclass.yaml
apiVersion: v1 
kind: Pod 
metadata:
  name: nginx-runc 
spec:     
  runtimeClassName: runC 

 

The value of the runtime class cannot be changed on the pod level, but it can be changed on the deployment level 

 

Deployment-Runtimeclass.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: sandboxed-nginx
spec:
  replicas: 2
  selector:
    matchLabels:
      app: sandboxed-nginx
  template:
    metadata:
      labels:
        app: sandboxed-nginx
    spec:
      runtimeClassName: kata. # ---> This can be changed
      containers:
      - name: nginx
        image: nginx
        ports:
        - containerPort: 80
          protocol: TCP
          

User-stories

  • As a cluster-admin, I would like to be able to differentiate between a normal pod and a Katacontainer pod from the UI.
  • As a developer, I would like to create katacontainers-based pods without dealing with YAML, i.e., from the UI.
  • As a developer, I would like to switch my deployments to use Kata instead on runC (native). 

Requirements

  • Kata runtime MUST be viewable when checking running workloads.
  • A checkbox or a similar method to create Katacontainers from the UI MUST be provided.
  • The above two requirements MUST be tested.

 

 

References

 [1] https://docs.openshift.com/container-platform/4.6/rest_api/workloads_apis/pod-core-v1.html 
 

We should show the runtime class on workloads pages and add a badge to the heading in the case a workload uses Kata. A workload uses Kata if its pod template has `runtimeClassName` set to `kata`.

Acceptance Criteria:

  • Kata runtime must be viewable when checking running workloads, including Pods, ReplicaSets, ReplicationControllers, StatefulSets, Deployments, and DeploymentConfigs.
  • Automated test must be written to verify coverage

 

Andrew Ronaldson indicated that adding a "kata" badge in the heading would be too much noise around other heading badges (ContainerCreating, Failed, etc).

 

Incomplete Features

When this image was assembled, these features were not yet completed. Therefore, only the Jira Cards included here are part of this release

The details of this Jira Card are restricted (Red Hat Employee and Contractors only)

Epic Goal

The OCP Console needs to detect if the ACM Operator has been installed, if detected then a new multi-cluster perspective option shows up in the perspective chooser.

As a user I need the ability to to switch to the the ACM UI from the OCP Console and vice versa without requiring the user to login multiple times.

This option also needs to be hidden if the user doesn't have the correct RBAC.

Marvel design mockup

Why is this important?

  • Multi-cluster functionality is very important to our users. We need to provide a seamless experience for users.

The console should detect the presence of the ACM operator and add an Advanced Cluster Management item to the perspective switcher. We will need to work with the ACM team to understand how to detect the operator and how to discover the ACM URL.

Additionally, we will need to provide a query parameter or URL fragment to indicate which perspective to use. This will allow ACM to link back to the a specific perspective since it will share the same perspective switcher in its UI. ACM will need to be able to discover the console URL.

This story does not include handling SSO, which will be tracked in a separate story.

We need to determine what RBAC checks to make before showing the ACM link.

Acceptance Criteria

1. Console shows a link to ACM in its perspective switcher
2. Console provides a way for ACM to link back to a specific perspective
3. The ACM option only appears when the ACM operator is installed
4. ACM should open in the same browser tab to give the appearance of it being one application
5. Only users with appropriate RBAC should see the link (access review TBD)

Feature Overview

We drive OpenShift cross-market customer success and new customer adoption with constant improvements and feature additions to the existing capabilities of our OpenShift Core Networking (SDN and Network Edge). This feature captures that natural progression of the product.

Goals

  • Feature enhancements (performance, scale, configuration, UX, ...)
  • Modernization (incorporation and productization of new technologies)

Requirements

  • Core Networking Stability
  • Core Networking Performance and Scale

  • Core Networking UX (Observability)
  • Core Networking Security and Compliance

In Scope

  • Network Edge (ingress, DNS, LB)
  • SDN (CNI plugins, openshift-sdn, OVN, network policy, egressIP, egress Router, ...)
  • Networking Observability

Out of Scope

There are definitely grey areas, but in general:

  • CNV
  • Service Mesh
  • CNF

We need to verify that no new CoreDNS dual stack features require any configuration changes or feature flags.
(All dual stack changes should just work once we rebase to coredns v1.8.1).

See https://github.com/coredns/coredns/pull/4339 .

We also need to verify that cluster DNS works for both v4 and v6 for a dual stack cluster IP service. (ie request via A and AAAA, make sure you get the desired response, and not just one or the other). A brief CI test on our dual stack metal CI might make the most sense here (KNI Might have a job like this already, need to investigate our options to add dual stack coverage to openshift/coredns).

This story is for actually updating the version of CoreDNS in github.com/openshift/coredns. Our fork will need to be rebased onto https://github.com/coredns/coredns/releases/tag/v1.8.1, which may involve some git fu. Refer to previous CoreDNS Rebase PR's for any pointers there.

The multiple destinations provided as a part of the allowedDestinations field is not working as it used to on OCP4: https://github.com/openshift/images/blob/master/egress/router/egress-router.sh#L70-L109

 

We need to parse this from the NAD and modify the iptables here to support them:

https://github.com/openshift/egress-router-cni/blob/master/pkg/macvlan/macvlan.go#L272-L349

 

Testing:

1) Created NAD:

[dsal@bkr-hv02 surya_multiple_destinations]$ cat nad_multiple_destination.yaml 
---
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
 name: egress-router
spec:
 config: '{
     "cniVersion": "0.4.0",
     "type": "egress-router",
     "name": "egress-router",
 "ip": {
     "addresses": [
         "10.200.16.10/24"
     ],
     "destinations": [
         "80 tcp 10.100.3.200",
         "8080 tcp 203.0.113.26 80",
         "8443 tcp 203.0.113.26 443"
     ],
     "gateway": "10.200.16.1"
  }
}'

2) Created pod:

[dsal@bkr-hv02  surya_multiple_destinations]$ cat egress-router-pod.yaml 
---
apiVersion: v1
kind: Pod
metadata:
  name: egress-router-pod
  annotations:
    k8s.v1.cni.cncf.io/networks: egress-router
spec:
  containers:
    - name: openshift-egress-router-pod
      command: ["/bin/bash", "-c", "sleep 999999999"]
      image: centos/tools
      securityContext:
        privileged: true

3) Checked IPtables:

[root@worker-1 core]# iptables-save -t nat 
Generated by iptables-save v1.8.4 on Mon Feb 1 12:08:05 2021
*nat
:PREROUTING ACCEPT [0:0]
:INPUT ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A POSTROUTING -o net1 -j SNAT --to-source 10.200.16.10
COMMIT # Completed on Mon Feb 1 12:08:05 2021

As we can see, only the SNAT rule is added. The DNAT doesn't get picked up because of the syntax difference.

Feature Overview

Plugin teams need a mechanism to extend the OCP console that is decoupled enough so they can deliver at the cadence of their projects and not be forced in to the OCP Console release timelines.

The OCP Console Dynamic Plugin Framework will enable all our plugin teams to do the following:

  • Extend the Console
  • Deliver UI code with their Operator
  • Work in their own git Repo
  • Deliver at their own cadence

Goals

    • Operators can deliver console plugins separate from the console image and update plugins when the operator updates.
    • The dynamic plugin API is similar to the static plugin API to ease migration.
    • Plugins can use shared console components such as list and details page components.
    • Shared components from core will be part of a well-defined plugin API.
    • Plugins can use Patternfly 4 components.
    • Cluster admins control what plugins are enabled.
    • Misbehaving plugins should not break console.
    • Existing static plugins are not affected and will continue to work as expected.

Out of Scope

    • Initially we don't plan to make this a public API. The target use is for Red Hat operators. We might reevaluate later when dynamic plugins are more mature.
    • We can't avoid breaking changes in console dependencies such as Patternfly even if we don't break the console plugin API itself. We'll need a way for plugins to declare compatibility.
    • Plugins won't be sandboxed. They will have full JavaScript access to the DOM and network. Plugins won't be enabled by default, however. A cluster admin will need to enable the plugin.
    • This proposal does not cover allowing plugins to contribute backend console endpoints.

Related to CONSOLE-2380

We need a way for cluster admins to disable a console plugin when uninstalling an operator if it's enabled in the console operator config. Otherwise, the config will reference a plugin that no longer exists. This won't prevent console from loading, but it's something that we can clean up during uninstall.

The UI will always remove the console plugin when an operator is uninstalled. There will not be an option to keep the operator. We should have a sentence in the dialog letting the user know that the plugin will disabled when the operator is uninstalled (but only if the CSV has the plugin annotation).

If the user doesn't have authority to patch the operator config, we should warn them that the operator config can't be updated to remove the plugin.

When moving to OCP 4 we didn't port the metrics charts for Deployments, Deployment Configs, StatefulSets, DaemonSets, ReplicaSets, and ReplicationControllers. These should be the same charts that we show on the Pods page: Memory, CPU, Filesystem, Network In and Out.

This was only done for pods.

We need to decide if we want use a multiline chart or some other representation.

This would let us import YAML with multiple resources and add YAML templates that create related resources like image streams and build configs together.

See CONSOLE-580

Acceptance criteria:

  • Users should be able to drag multiple files into the import yaml.
    • the yaml files should be displayed in the editor separated by "- - -"
  • After clicking create
    • a dry run will be initiated and will report back any errors
    • upon receiving no errors from the dry run, the resources will be created
    • the results page will appear showing links for each resource

Story:
As a user viewing the pod logs tab with a selected container, I want the ability to view past logs if they are available for the container.

Acceptance Criteria:

  • Provide a mechanism to expose past logs, if they are available.

 

Design doc: https://docs.google.com/document/d/1PB8_D5LTWhFPFp3Ovf85jJTc-zAxwgFR-sAOcjQCSBQ/edit#

The work on this story is dependent on following changes:

 

The console already supports custom routes on the operator config. With the new proposed CustomDomains API introduces a unified way how to stock install custom domains for routes, which both names and serving cert/keys, customers want to customise. From the console perspective those are:

  • openshift-console / console
  • openshift-console / downloads (CLI downloads)

 

The setup should be done on the Ingress config. There two new fields are introduced:

  • ComponentRouteSpec - contains configuration of the for the custom domain(name, namespace, custom hostname, TLS secret reference)
  • ComponentRouteStatus - contains status of the custom domain(condition, previous hostname, rbac needed to read the TLS secret, ...)

 

Console-operator will be only consuming the API and check for any changes. If a custom domain is set for either `console` or `downloads` route in the `openshift-console` namespace, console-operator will read the setup set a custom route accordingly. When a custom route will be setup for any of console's route, the default route wont be deleted, but instead it will updated so it redirects to the custom one. This is done because of two reasons:

  1. we want to prevent somebody from stealing the default hostname of both routes (console, downloads)
  2. we want to prevent users from having unusable bookmarks that are pointing to the default hostname

 

Console-operator will still need to support the CustomDomain API that is available on it's config.

Acceptance criteria:

  • Console supports the new CustomDomains API for configuring a custom domain for both `console` and `downloads` routes
  • Console falls back to the deprecated API in the console operator config if present
  • Console supports the original default domains and redirects to the new ones

 

Questions:

  • Which CustomDomain API takes precedens? Ingress config vs. Console-operator config. Can upgrade cause any issues?

 Feature Overview

This will be phase 1 of Internationalization of the OpenShift Console.

 Phase 1 will include the following:

  1. UI based language Selector instead of using browser detection
  2. Externalize all hard coded strings in the client code including all OpenShift static plugins
    1. Admin Console
    2. Dev Console
    3. Serverless
    4. Pipelines
    5. CNV
    6. OCS
    7. CSO
  3. Localized Date\Time
  4. Setup all processes, infrastructure, and testing required
  5. We will start with support for Chinese and Japanese lang

Phase 1 will not include:

  1. Dynamically generated UI (Operator, OpenAPIV3Schema)
    1. Operators that surface informational messages may not have translations available
  2. Strings from non client code
    1. This may include items such as events surfaced from Kuberenetes, alerts, and error messages displayed to the user or in logs
  3. Localization of logging messages at any level is not in scope
  4. Any CLI
  5. Language support for left to right languages ie Arabic

POC

 Initial POC PR

Goals

Internationalization has become table stakes. OpenShift Console needs to support different languages in each of the major markets. This is key functionality that will help unlock sales in different regions.

 

Requirements

 

Requirement Notes isMvp?
Language Selector   YES
Localized Date. + Time   YES
Externalization and translation of all client side strings   YES
Translation for Chinese and Japanese   YES
Process, infra, and testing capabilities put into place   YES
CI - MUST be running successfully with test automation This is a requirement for ALL features. YES
     

  

Out of Scope

  1. Dynamically generated UI (Operator, OpenAPIV3Schema)
    1. Operators that surface informational messages may not have translations available
  2. Strings from non client code
    1. This may include items such as events surfaced from Kuberenetes, alerts, and error messages displayed to the user or in logs
  3. Localization of logging messages at any level is not in scope
  4. Any CLI support
  5. Language support for left to right languages ie. Arabic

 

Assumptions

  • Each static plugin team will be responsible for externalizing all their client code strings.
  • Quick Starts will need to be translated.

Customer Considerations

We are rolling this feature in phases, based on customer feedback, there may be no phase 2.

Documentation Considerations

I believe documentation already supports a large language set.

Epic Goal

  • This is the continuation of the Internationalization work... the following items remain:
    • All existing QuickStarts get Translated
    • Automation Completed
    • Any remaining items cleaned up

Why is this important?

  • Automating as much as possible with the detecting duplicate strings, building, translation drops will ensure we will be successful for all future releases
  • Quick Start are important part of the product that enable our users to maximize usage of the Console
  • Best to clean up anything left over to reduce future Tech Debt

Acceptance Criteria

  • Quick Starts are translated 
  • Everything is automated for building, and pushing translation drops to the globalization team
  • Source code should be up to quality standards

Previous Work (Optional):

  1. https://issues.redhat.com/browse/CONSOLE-2325

We need to automate how we send and receive updated translations using Memsource for the Red Hat Globalization team. The Ansible Tower team already has automation in place that we might be able to reuse.

Acceptance Criteria:

  • We have a script that takes the current messages from the console repos and pushes them to Memsource
  • We have a script that pulls the updated translations from Memsource and creates a PR against openshift/console
  • We work with the DPTP team to determine if this process can be automated such that it runs periodically (e.g. once a sprint)

Complete Epics

This section includes Jira cards that are linked to an Epic, but the Epic itself is not linked to any Feature. These epics were completed when this image was assembled

Goal:

Record the lastImageChangeTriggeredID field in the BuildConfig status, instead of spec.

Problem:

BuildConfigs use the lastImageChangeTriggeredID field to record the SHA of the last image used to trigger a build. This information should only be managed by the Build controllers and be placed in the BuildConfig status. By keeping the data in spec, cluster admins and developers can easily alter or remove this information.

Why is this important?

Moving this information to status is a prerequisite for using GitOps to manage BuildConfigs with ImageChange triggers.

Dependencies

None

Stories and Deliverables

  • BUILD-186: Record LastImageChangeTriggeredID in status

Estimate: (XS, S, M, L, XL, XXL) S

Previous Work:

https://bugzilla.redhat.com/show_bug.cgi?id=1876500

User Stories:

As an OpenShift engineer
I want to image change triggers to record their information BuildConfig status
So that eventually changes to ImageChange triggers in the BuildConfig spec do not cause builds to launch

As a developer using OpenShift to build images
I want to trigger a build when the base image of my application changes
So that bug fixes and security patches are applied to my application.

As an OpenShift cluster admin
I want to be alerted if something cleared the LastImageTriggeredID in a BuildConfig
So that I am aware that cluster users are relying on deprecated behavior.

Success Criteria:

1. Image change triggers record lastImageTriggeredID in the BuildConfig's status
2. Customers are notified that lastImageTriggeredID is deprecated in BuildConfig's spec
3. Customers are alerted if their users are relying on deprecated behavior

Open Questions:


See https://docs.google.com/document/d/1thcVR31TElJBXBGmyaYXZ9jRejp5W4-ppNYn4g3_mgk/edit# for a fuller explanation on how to use this template.

User Story

As a developer using OpenShift to build images
I want to trigger a build when the base image of my application changes
So that bug fixes and security patches are applied to my application.

Acceptance Criteria

Docs Impact

Release note should inform customers that the lastImageChangeTriggeredID field in the BuildConfig spec is deprecated, and will be ignored in OCP 4.9. Users relying on this information should update their scripts and jobs to read the triggered image ID from BuildConfig status. 

Please see https://issues.redhat.com/browse/RHDEVDOCS-2738 for more details.

Launch Checklist

Dependencies identified
Blockers noted and expected delivery timelines set
Design is implementable
Acceptance criteria agreed upon
Story estimated

Notes

If lastImageTriggeredID is set to the empty string or nil, today this will trigger a build. By moving the data to status, we can ignore the lastImageTriggeredID field in spec in a future release. To give users proper notice, we are not going to remove the current behavior until a later release.

A deprecation notice will need to be added to the release notes upon completion.

Changes will be needed in the following:

1. API
2. openshift-apiserver
3. openshift-controller-manager (build controller)

See https://bugzilla.redhat.com/show_bug.cgi?id=1876500.

Epic Goal

  • Port all remaining Protractor tests to Cypress

Why is this important?

  • Protractor is very hard to debug when tests fail/flake
  • Once all protractor tests are ported we can remove all Protractor dependencies, scripts, and configuration files.
  • Cypress has better debugging, plug-ins, and reporting tools

Acceptance Criteria

  • CI - MUST be running successfully with tests automated

This task adds support for setting socket options SO_REUSEADDR and SO_REUSEPORT to etcd listeners via ListenConfig. These options give the flexibility to cluster admins who wish to more explicit control of these features. What we have found is during etcd process restart there can be a considerable time waiting for the port to release as it is held open by TIME_WAIT which on many systems is 60s.

Description of problem:

In one of our customer's clusters we see that new network policies are not created or updated by OVN-Kubernetes.
For one application this means it cannot reach the DNS service because the network policy that allows that is not being implemented.

In our own test on this cluster, pods in a namespace CAN reach each other despite this network policy:
~~~
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
creationTimestamp: "2022-01-27T14:41:05Z"
generation: 2
name: default-deny
namespace: customer-debug
resourceVersion: "311846645"
uid: 87646222-c86d-4000-8997-7f0557ac34cf
spec:
podSelector: {}
policyTypes:

  • Ingress
  • Egress
    ~~~

In one of our dev clusters this network policy is enforced.

— Additional comment from Tim Rozet on 2022-02-03 16:04:01 UTC —

Upon finishing my analysis of the logs there are several bugs/errors happening here. All of which compound to either make network policies fail to be enforced properly or may cause them to stay enforcing when they shouldn't be:

1.policy.go:818] Failed to set ports in PortGroup for network policy ie-st-montun-filebeat/default-deny: Reconnecting...Transaction Failed due to an error: syntax error details: expected ["set", <array>] in

{update Port_Group map[name:a11253394058733577533 ports:0xc001f1a1b0] [] [] [] 0 [[name == a11253394058733577533]] }

This is due to a bug in the go-ovn library that was fixed in 4.9. I'm going to backport the same fix to 4.8z.

2. policy.go:1166] no pod IPs found on pod redhat-marketplace-brhvf: could not find OVN pod annotation in map[openshift.io/scc:anyuid operatorframework.io/managed-by:marketplace-operator]

This error is spammed throughout the log, but is benign. On pod add we could fail to get the OVN annotation due to racing with pod handler. However, once the pod handler annotates the pod an update event will happen and this code will be executed again. I'm going to ignore printing this error on pod add.

3. policy.go:733] logical port cd-argocd-cdteam_testssl2 not found in cache

This is the same as https://bugzilla.redhat.com/show_bug.cgi?id=2037884. The bug references stateful sets, but this was really true about any pod being added. When the network policy is created or pods are added that belong to the network policy's namespace, we attempt to get the pod's information from an internal cache. This races with the pod being added to the cache by the pod handler. The fix makes the network policy handler wait until the pod is added to the cache. Otherwise the network policy is created and potentially skips being applied to some pods in the namespace. This is already fixed in 4.8.29

4. policy.go:1166] failed to add IPs ... set contains duplicate value

The duplicate value here being added is a VIP for a load balancer. In 4.9 and later there is a lower probability of this happening (because we no longer store an internal cache, so there shouldn't be duplicates), however I'm still going to add checks to ensure we filter out any duplicate values before adding to them to the cache or sending the RPC to OVN. I'm going to ensure a proper fix going in master and then backport to 4.8z.

5. E0125 18:40:32.759129 1 policy.go:955] Failed to create port_group for network policy allow-prometheus in namespace ie-st-montun-filebeat

This is the most egregious bug. First of all the log is is not printing the actual error. Second, this failure causes the network policy to fail creation, and then it is not retried again (unless the policy is updated). We need a retry mechanism to attempt to recreate the policy just like we do with pods. This will require a heavier fix in master and then backport down to 4.8z.

@trozet@redhat.com Do you have a link for the BZ / PR for:

1.policy.go:818] Failed to set ports in PortGroup for network policy ie-st-montun-filebeat/default-deny: Reconnecting...Transaction Failed due to an error: syntax error details: expected ["set", <array>] in

This is due to a bug in the go-ovn library that was fixed in 4.9. I'm going to backport the same fix to 4.8z.

Many thanks,

Setting a telemeter proxy in the cluster-monitoring-config config map does not work as expected

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
the following KCS details steps to add a proxy.
The steps have been verified at 4.7 but do not work at 4.8, 4.9 or 4.10

https://access.redhat.com/solutions/6172402

When testing at 4.8, 4.9 and 4.10 the proxy setting where also nested under `telemeterClient`

which triggered a telemeter restart but the proxy setting do not get set in the deployment as they do in 4.7

Actual results:

4.8, 4.9 and 4.10 without the nested `telemeterClient`
does not trigger a restart of the telemeter pod

Expected results:

I think the proxy setting should be nested under telemeterClient
but should set the environment variables in the deployment

Various CI steps use the upi-installer container for it's access to the

curl yq directly from GitHub. We can save ourselves some headaches
when GitHub is down by just embedding the binary in the image already.

Whenever GitHub has issues or throttles us, YQ hash mismatch error out. The hash mismatch error is because github is probably returning an error page, although our scripts hide it.

Bug #2070318
+++

Description of problem:
In OCP VRRP deployment (using OCP cluster networking), we have an additional data interface which is configured along with the regular management interface in each control node. In some deployments, the kubernetes address 172.30.0.1:443 is nat’ed to the data management interface instead of the mgmt interface (10.40.1.4:6443 vs 10.30.1.4:6443 as we configure the boostrap node) even though the default route is set to 10.30.1.0 network. Because of that, all requests to 172.30.0.1:443 were failed. After 10-15 minutes, OCP magically fixes it and nat’ing correctly to 10.30.1.4:6443.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:

1.Provision OCP cluster using cluster networking for DNS & Load Balancer instead of external DNS & Load Balancer. Provision the host with 1 management interface and an additional interface for data network. Along with OCP manifest, add manifest to create a pod which will trigger communication with kube-apiserver.

2.Start cluster installation.

3.Check on the custom pod log in the cluster when the first 2 master nodes were installing to see GET operation to kube-apiserver timed out. Check nft table and chase the ip chains to see the that the data IP address was nat'ed to kubernetes service IP address instead of the management IP. This is not happening all the time, we have seen 50:50 chance.

Actual results:
After 10-15 minutes OCP will correct that by itself.

Expected results:
Wrong natting should not happen.

Hi Ben,

We were deploying Contrail CNI with OCP. However, this issue happens at very early deployment time, right after the bootstrap node is started
and there's no SDN/CNI there yet.

Can you please provide the iptables rules causing the DNAT as well as the routes on the host? Might be easiest to get a sosreport during initial bring up during that 10-15 min when the problem occurs.

All nodes have two interfaces:

eth0: 10.30.1.0/24
eth1: 10.40.1.0/24

machineNetwork is 10.30.1.0/24
default route points to 10.30.1.1

The kubeapi service ip is 172.30.0.1:443

all Kubernetes services are supposed to be reachable via machineNetwork (10.30.1.0/24)

To make the kubeapi service ip reachable in hostnetwork, something (openshift installer?) creates a set of nat rules which translates the service ip to the real ip of the nodes which have kubeapi active.

Initially kubeapi is only active on the bootstrap node so there should be a nat rule like

172.30.0.1:443 -> 10.30.1.10:6443 (assuming that 10.30.1.10 is the bootstrap nodes' ip address in the machine network)

However, what we see is
172.30.0.1:443 -> 10.40.1.10:6443 (which is the bootstrap nodes' eth1 ip address)

The rule is configured on the controller nodes and lead to asymmetrical routing as the controller sends a packet FROM machineNetwork (10.30.1.x) to 172.30.0.1 which is then translated and forwarded to 10.40.1.10 which then tries to reply back on the 10.40.1.0 network which fails as the request came from 10.30.1.0 network.

So, we want to understand why openshift installer picks the 10.40.1.x ip address rather than the 10.30.1.x ip for the nat rule. What's the mechanism for getting the ip in case the system has multiple interfaces with ips configured.

Note: after a while (10-20 minutes) the bootstrap process resets itself and then it picks the correct ip address from the machineNetwork and things start to work.

on 2022-04-21 20:57:24 UTC —

Looking at the must-gather I think your iptables rules are most likely coming from the fact that kube-proxy is installed:

[trozet@fedora must-gather.local.288458111102725709]$ omg get pods -n openshift-kube-proxy
NAME READY STATUS RESTARTS AGE
openshift-kube-proxy-kmm2p 2/2 Running 0 19h
openshift-kube-proxy-m2dz7 2/2 Running 0 16h
openshift-kube-proxy-s9p9g 2/2 Running 1 19h
openshift-kube-proxy-skrcv 2/2 Running 0 19h
openshift-kube-proxy-z4kjj 2/2 Running 0 19h

I'm not sure why this is installed. Is it intentional? I don't see the configuration in CNO to enable kube-proxy. Anyway the node IP detection is done via:
https://github.com/kubernetes/kubernetes/blob/f173d01c011c3574dea73a6fa3e20b0ab94531bb/cmd/kube-proxy/app/server.go#L844
Which just looks at the IP of the node. During bare metal install a VIP is chosen and used with keepalived for kubelet to have kapi access. I don't think there is any NAT rule for services until CNO comes up. So I suspect what really is happening is your node IP is changing during install, and kube-proxy is getting deployed (either intentionally or unintentionally) and that is causing the behavior you see. The node IP is chosen via the node ip configuration service:
https://github.com/openshift/machine-config-operator/blob/da6494c26c643826f44fbc005f26e0dfd10513ae/templates/common/_base/units/nodeip-configuration.service.yaml
This service will determine the node ip via which interfaces have a default route and which one has the lowest metric. With your 2 interfaces, do they both have default routes? If so, are they using dhcp and perhaps its random which route gets installed with a lower metric?

— Additional comment from
trozet@redhat.com
on 2022-04-21 21:13:15 UTC —

Correction: looks like standalone kube-proxy is installed by default when the provider is not SDN, OVN, or kuryr so this looks like the correct default behavior for kube-proxy to be deployed.

— Additional comment from
lpbinh@gmail.com
on 2022-04-25 04:05:14 UTC —

Hi Tim,

You are right, kube-proxy is deployed by default and we don't change that behavior.

There is only 1 default route configured for the management interface (10.30.1.x) , we used to have a default route for the data/vrrp interface (10.40.1.x) with higher metric before. As said, we don't have the default route for the second interface any more but still encounter the issue pretty often.

— Additional comment from
trozet@redhat.com
on 2022-04-25 14:24:05 UTC —

Binh, can you please provide a sosreport for one of the nodes that shows this behavior? Then we can try to figure out what is going on with the interfaces and the node ip service. Thanks.

— Additional comment from
trozet@redhat.com
on 2022-04-25 16:12:04 UTC —

Actually Ben reminded me that the invalid endpoint is actually the boostrap node itself:
172.30.0.1:443 -> 10.30.1.10:6443 (assuming that 10.30.1.10 is the bootstrap nodes' ip address in the machine network)

vs
172.30.0.1:443 -> 10.40.1.10:6443 (which is the bootstrap nodes' eth1 ip address)

So maybe a sosreport off that node is necessary? I'm not as familiar with the bare metal install process, moving back to Ben.

Created attachment 1875024 [details]sosreport-part2

Hi Tim,

We observe this issue when deploying clusters using OpenStack instances as our infrastructure is based on OpenStack.

I followed the steps here to collect the sosreport:
https://docs.openshift.com/container-platform/4.8/support/gathering-cluster-data.html
Got the sosreport which is 22MB which exceeds the size permitted (19MB), so I split it to 2 files (xaa and xab), if you can't join them then we will need to put the collected sosreport on a share drive like we did with the must-gather data.

Here are some notes about the cluster:

First two control nodes are below, ocp-binhle-8dvald-ctrl-3 is the bootstrap node.

[core@ocp-binhle-8dvald-ctrl-2 ~]$ oc get node
NAME STATUS ROLES AGE VERSION
ocp-binhle-8dvald-ctrl-1 Ready master 14m v1.21.8+ed4d8fd
ocp-binhle-8dvald-ctrl-2 Ready master 22m v1.21.8+ed4d8fd

We see the behavior that wrong nat'ing was done at the beginning, then corrected later:

This issue is causing delays in Juniper's CI/CD pipeline and makes for a less than ideal user experience for deployments.

I'm getting a lot of pressure from the partner on this for an update and progress. I've had them open a case [1] to help progress.

Please let us know if there is any other data needed by Juniper or if there is anything I can do to help move this forward.

I'm currently discussing this with some other internal teams because I'm unfamiliar with this type of bootstrap setup. I need to understand what the intended behavior is before we decide on a path forward.

Okay, I see now that this is an assisted installer deployment. Can we get the cluster ID assigned by AI so we can take a look at the logs on our side? Thanks.

Here is the cluster ID, copied from the bug description:
ClusterID: 24bbde0b-79b3-4ae6-afc5-cb694fa48895

In regard to your earlier question about OpenStack & baremetal (2022-06-03 18:15:17 UTC):

We had an issue with platform validation in OpenStack earlier. Host validation was failing with the error message “Platform network settings: Platform OpenStack Compute is allowed only for Single Node OpenShift or user-managed networking.”

It's found out that there is no platform type "OpenStack" available in [
https://github.com/openshift/assisted-service/blob/master/models/platform_type.go#L29
] so we set "baremetal" as the platform type on our computes. That's the reason why you are seeing baremetal as the platform type.

Thank you

Hey, first you are currect, When you set 10.30.1.0/24 as the machine network, the bootstrap process should use the IP on that subnet in the bootstrap node.

I'm trying to understand how exactly this cluster was installed.
You are using on-prem deployment of assisted-installer (podman/ACM)?
You are trying to form a cluster from OpenStack Vms?
You set the platform to Baremetal where?
Did you set user-managed-netwroking?

Some more info, when using OpenStack platform you should install the cluster with user-managed-netwroking.
And that's what the failing validation is for.

@Eran Cohen:

Please see my response inline.

You are using on-prem deployment of assisted-installer (podman/ACM)?
--> Yes, we are using on-prem deployment of assisted-installer.

You are trying to form a cluster from OpenStack Vms?
--> Yes.

You set the platform to Baremetal where?
--> It was set in the Cluster object, Platform field when we model the cluster.

Did you set user-managed-netwroking?
--> Yes, we set it to false for VRRP.

OK, as noted before when using OpenStack platform you should install the cluster with user-managed-netwroking (set to true).
Can you explain how you workaround this failing validation? “Platform network settings: Platform OpenStack Compute is allowed only for Single Node OpenShift or user-managed networking.”
What does this mean exactly? 'we set "baremetal" as the platform type on our computes'

To be honest I'm surprised that the installation was completed successfully.

@
oamizur@redhat.com
I thought installing on OpenStack VMs with baremetal platform (user-managed-networking=false) will always fail?

@
itsoiref@redhat.com
: I will reproduce and collect the logs. Is that supposed to be included in the provided must-gather?
@
ercohen@redhat.com
:

  • user-managed-networking set to true when we use external Load Balancer and DNS server. For VRRP we use OpenShift's internal LB and DNS server hence it's set to false, following the doc.
  • As explained OpenShift returns platform type as 'none' for OpenStack:
    https://github.com/openshift/assisted-service/blob/master/models/platform_type.go#L29
    , therefore we set the platformtype as 'baremetal' in the cluster object for provisioning the cluster using OpenStack VMs.

@
itsoiref@redhat.com
as explained it's just a workaround on our side to make OCP work in our lab, and from my understanding on OCP perspective it will see that deployment is on baremetal only, not related to OpenStack (please correct me if I am wrong).

We have been doing thousands of OCP cluster deployments in our automation so far, if it's why validation is failing then it should be failing every time. However it only occurs occasionally when nodes have 2 interfaces, using OCP internal DNS and Load balancer, and sometime resolved by itself and sometime not.

The issue is that kube-api service advertise wrong ip but it does it cause kubelet chooses the one arbitrary and we currently have no mechanism to set kubelet ip, especially in bootstrap flow.

@
itsoiref@redhat.com
how do you perform OCP deployment in setups that have multiple interfaces if letting kubelet chooses an interface arbitrary instead of configuring a specific IP address for it to listen on? With what you describe above chance of deployment failure in system with multiple interfaces would be high.

When logged in as a non-admin user, I can't silence alerts from the Dev Console.

Version-Release number of selected component (if applicable):

4.10 but the same issue may exist for previous versions.

How reproducible:

 

Steps to Reproduce:

1. Login to the dev console as a non-admin user. 
2. Follow the OCP documentation to deploy the example application including the service monitor and the rule (the user needs to be granted the monitoring-edit role). See https://docs.openshift.com/container-platform/4.9/monitoring/enabling-monitoring-for-user-defined-projects.html for details. 
3. Go to the Observe > Alerts page and disable notifications during 30 minutes for the VersionAlert alert. 

Actual results:

The alert notification seems to be disabled but on refresh, the notification is still enabled.

Expected results:

The notification is permanently disabled.

Additional info:

The console backend hits the wrong service which results in a 403 response code, it should use the tenancy-aware service.

User Story

Pull in the latest openshift/library content into the samples operator
If image eco e2e's fail, work with upstream SCL to address

Acceptance Criteria

  • Samples operator installs current official content in openshift/library
  • List of removed/EOL images is prepared for docs update

Docs Impact

List of EOL images needs to be sent to the Docs team and added to the release notes.

console-operator codebase contains a lot of inline manifests. Instead we should put those manifests into a `/bindata` folder, from which they will be read and then updated per purpose.

discover-etcd-initial-cluster was written very early on in the cluster-etcd-operator life cycle. We have observed at least one bug in this code and in order to validate logical correctness it needs to be rewritten with unit tests.

PR: https://github.com/openshift/etcd/pull/73

1) We want to fix the order of Imports in the files.

2) We want to have vendor import, followed by console/package import and then relative imports should come at last.

Can be done manually or introduce some linter rules for this.

+++ This bug was initially created as a clone of Bug #2060329 +++

Description of problem:
As a user, I was stopped from using the developer perspective when switching into a namespace with a lot of workloads (Deployments, Pods, etc.)

This is a follow up on https://bugzilla.redhat.com/show_bug.cgi?id=2006395

We recommend the following safety precautions against a lazy or crashing topology, also if we continue to work on performance improvements to allow more workloads rendered.

At the moment we expect that a topology with around about 100 nodes could be displayed. This could also depend on the node types, the used browser, the computer power of the PC, and how often the workload conditions changes.

Recommended safety guard:
The topology graph (maybe the list as well) should check how many nodes are fetched and will be rendered.

1. We need to evaluate if we could make this decision based on the shown graph nodes and edges or the number of underlying resources.

For example, is it required to count each Pod in a Deployment or not?

2. Based on a threshold (~ 100?) the topology graph should skip the rendering.

3. We should show a 'warning page' instead, which explains that the topology could not handle this amount of X nodes at the moment.

4. This page could have an option to "Show topology anyway" so that users who don't have issues here can still use the topology.

What is the business impact? Please also provide timeframe information.
We failed to recover from a major outage due to this bug.

Where are you experiencing the behavior? What environment?
Production and all envs.

When does the behavior occur? Frequency? Repeatedly? At certain times?
It appeared only once so far, but can appear in larger scaling scenarios.

Version-Release number of selected component (if applicable):
4.8.39

Actual results:

With the panicing machine-controller, no new instances could be provisioned, resulting in an unscalable cluster. The solution/workaround to the problem was to delete the offending Machines.
Expected results:
Make the cluster scaleable again without deleting manually.

Description of problem:

Over time the kubelet slowly consumes memory until, at some point, pods are no longer able to start on the node; coinciding with this are container runtime errors. It appears that even rebooting the node does not resolve the issue once it occurs - the node has to be completely rebuilt.

How reproducible: Consistently

Actual results: Pods are eventually unable to start on the node; rebuilding the node is the only workaround

Expected results: kubelet/crio would continue working as expected

OVERVIEW
========

  • Ford is having an ongoing issue where they seeing node memory using slowly increasing over time until pods are unable to start, and errors like the following start to show up:

"Error: relabel failed /var/lib/kubelet/pods/47eb3e14-a631-412b-b07a-b19499faddbb/volumes/kubernetes.io~csi/pvc-05a55ed9-d63b-4c68-b3af-644a4353d9be/mount: lsetxattr /var/lib/kubelet/pods/47eb3e14-a631-412b-b07a-b19499faddbb/volumes/kubernetes.io~csi/pvc-05a55ed9-d63b-4c68-b3af-644a4353d9be/mount: operation not permitted"

  • Once this happens the node is unusable and has to be rebuilt, as rebooting apparently does not solve the problem.
  • We originally thought that this was going to get resolved in BZ 2042175 which was eventually closed as a duplicate of BZ 2060494. Since BZ 2044438 represented the 4.9 fix (in 4.9.21, errata RHBA-2022:0488), we told customer to go ahead and upgrade to 4.9.21, but unfortunately this did not resolve the issue for them, hence the reason we are opening this BZ.
  • Ford has a very specific use case for OC -. they are mostly using the cluster to run large numbers of Tekton pipelines and are using some custom SCC's to get around current limitations in OCP filesystem support.

There is a lot of data available on case 2065749, though this is before they upgraded from 4.8 to 4.9. If there's any specific data that we haven't captured yet but would be helpful please let me know.

— Additional comment from lstanton@redhat.com on 2022-03-18 19:08:44 UTC —

The latest data from an occurrence before the customer upgraded to 4.9.21 can be found here (so this is from 4.8):

Would it possible to get your opinion on the above node data? Does anything look obviously out of line in terms of kubelet or crio behavior that might explain pods failing to start? I've requested newer data in the case.

    1. Kubelet

I noticed that pods are failing to be fully cleaned up and created within the kubelet: Failed to remove cgroup (will retry)

This means the pods are staying within Kubelet's memory and the kubelet is retrying the cleanup operation. (Effectively leaking memory).

Additionally, pods are failing to be started from Comment #1, after during the start phase with the selinux rename. The failure in the start phase leads me to believe we are hitting (1) (not backported yet into 4.9). PR 107845 fixes an issue where pods on CRI error are arbitrarily marked as terminated when they should be marked as waiting.

— Additional comment from dahernan@redhat.com on 2022-06-02 14:35:33 UTC —

Once this is verified, is it viable to also backport it to 4.8, 4.9 or 4.10(at least)? I do not observe any cherry pick or backport related to other versions (yet) but we have a customer (Swisscom) pushing for that, as this is impacting them.

Ford brought this up in my TAM meeting as a hot issue.

I need an ETA of when this will be in 4.10. This just needs to be a rough date. I know normally we don't share exact dates because timeframes could change.
