title: Jenkins sh script hangs when run in specific container
body: <p>I'm trying to automate deployments using the official ArgoCD docker image (<a href="https://hub.docker.com/r/argoproj/argocd/dockerfile" rel="nofollow noreferrer">https://hub.docker.com/r/argoproj/argocd/dockerfile</a>)</p>
  
  <p>I've created a declarative jenkins pipeline using the kubernetes plugin for the agents and define the pod using yaml, the container definition looks like this:</p>
  
  <pre><code>pipeline {
      agent {
          kubernetes {
              yaml """
  kind: Pod
  metadata:
    name: agent
  spec:
    containers:
    - name: maven
      image: maven:slim
      command:
      - cat
      tty: true
      volumeMounts:
        - name: jenkins-maven-cache
          mountPath: /root/.m2/repository
    - name: argocd
      image: argoproj/argocd:latest
      command:
      - cat
      tty: true
      ...
  </code></pre>
  
  <p>I'm trying to run commands inside that container, that step in the pipeline looks like this:</p>
  
  <pre><code>stage('Build') {
      steps {
          container('maven') {
              sh 'echo testing' // this works just fine
          }
      }
  }
  stage('Deploy') {
      steps {
          container('argocd') {
              sh "echo testing" // this does not work
              // more deploy scripts here, once sh works
          }
      }
  }
  </code></pre>
  
  <p>So I have two containers, one where the sh script works just fine and another where it doesn't. The sh scripts in the "argocd" container just hangs for 5 minutes and then Jenkins kills it, the exit message is: 
  <code>
  process apparently never started in /home/jenkins/agent/workspace/job-name@tmp/durable-46cefcae (running Jenkins temporarily with -Dorg.jenkinsci.plugins.durabletask.BourneShellScript.LAUNCH_DIAGNOSTICS=true might make the problem clearer)
  </code></p>
  
  <p>I can't do echo a simple string in this particular container.</p>
  
  <p>It works fine in other containers like the official for Maven from Docker, I use to build the spring boot application. I can also run commands directly in the argocd container manually from commandline with docker exec, but jenkins just won't in the pipeline for some reason.
  What could it be?</p>
  
  <p>I am running the latest version (1.33) of the durable task plugin.</p>
  
  <p><strong>Update:</strong>
  Turns out that the image for argo-cd (continuous deployment tool) <em>argoproj/argocd:latest</em> does not include other commands except <code>argocd</code>, so the issue was with the container image I tried to use and not Jenkins itself. My solution was to install the Argo-CD CLI into a custom docker container and use that instead of the official one.</p>
