Updated US source to: 8b35abf Merge pull request #1398 from akram/4.10-compute-bundle-plugins-in-build

gmontero@redhat.com  We release noted this deprecation as shown above in the "Release Notes Text" section. 

We also release noted the enhancement,  JKNS-132 as follows:

• With this update, you can run Jenkins agents as sidecar containers. You can use this capability to run any container image in a Jenkins pipeline that has a correctly configured pod template and Jenkins file. Now, to compile code, you can run two new pod templates named java-build and nodejs-builder as sidecar containers with Jenkins. These two pod templates use the latest Java and NodeJS versions provided by the java and nodejs image streams in the openshift namespace. The previous non-sidecar maven and nodejs pod templates have been deprecated. (JKNS-132)

Verified manually. Current open sub-task is automating our verification tests.

Updated US source to: 0c80872 Merge pull request #1364 from jitendar-singh/sidecar-smoke-test

rdlugyhe - release note text using the Enhancement guidelines at https://redhat-documentation.github.io/supplementary-style-guide/#release-notes:

With this update, we are both

• providing 2 new PodTemplates for use by the Kubernetes Plug-in in Jenkins, name "java-build" and "nodejs-builder", where the latest available Java version and NodeJS version provided by the "java" and "nodejs" ImageStreams in the "openshift" namespae are utilized when using those PodTemplates to compile code in those respective languages
• deprecating the "maven" and "nodejs" PodTemplates previously provided

OK jitensingh pkumari per adkaplan@redhat.com change to our project profiles in Jira, I've moved this Story to "Review", which is the analogous workflow state to what used to be "QE Review" with our prior settings in Jira.

Hopefully this story is now on your radar for composing and executing test cases so we can complete this work.

Thanks.

For reference, this simplified version of the sample from the code ready container folks worked:

```

def nodeLabel = 'spring-petclinic-pipeline-agent'

pipeline {
  agent {
    kubernetes {
      cloud 'openshift'
      label nodeLabel
      yaml """
apiVersion: v1
kind: Pod
metadata:
  labels:    "k8s.io/apimachinery/pkg/labels"

    worker: ${nodeLabel}
spec:
  containers:
  - name: jnlp
    image: registry.redhat.io/openshift4/ose-jenkins-agent-base:v4.2.15
    args: ['\$(JENKINS_SECRET)', '\$(JENKINS_NAME)']
  - name: java
    image: registry.redhat.io/codeready-workspaces/stacks-java-rhel8:2.0
    command:
    - cat
    tty: true
  imagePullSecrets:
    - name: jenkins-pull-secret
"""
    }
  }
  
  options

  stages {
    stage('Build App') {
      steps {
        container("java")

      }
    }
   
  }

 
}

```

So the hang I reported in my last comment disappeared after launching new clusters (4.6, 4.9, 4.10) the following day.  Have no idea what happened, but am currently unblocked.  We'll see how today's clusters make out

 
So something between 1.29.0 and 1.30.1 of the k8s plugin changed how things work, and broke the form of sidecar noted by the code ready container folks.  I'll start trying to see if I can gleam what changed exactly and if this is expected or a side effect, and if there is a config tweak which allows ^^ to work again.
 
 

a post planning question adkaplan@redhat.com abenaiss - if you all look at the various flavors of multiple container support for the k8s plugin at https://github.com/jenkinsci/kubernetes-plugin#multiple-containers-support, which one(s) of those were you considering "Deprecated Groovy format" ?

I think you all mean

```

podTemplate(containers: [ containerTemplate(name: 'maven', image: 'maven:3.8.1-jdk-8', command: 'sleep', args: '99d'), containerTemplate(name: 'golang', image: 'golang:1.16.5', command: 'sleep', args: '99d') ])

```

but wanted to make sure.

thanks
