Run K6 tests in jenkins using docker image

Grafana k6
1

I’m working on a Jenkins pipeline using the grafana/k6:0.57.0 Docker image, but I’m encountering an issue where commands within the container (e.g., ls, k6 version, etc.) are not executing when using the sh step. This setup used to work with the older loadimpact/k6 Docker image, where multiple tests could be triggered in the same container

podTemplate(label: LABEL, idleMinutes: 30,
  containers: [
      containerTemplate(name: 'k6-container', image: 'grafana/k6:0.57.0', command: 'cat', args: '', ttyEnabled: true ,alwaysPullImage: true)
    ]) {
      node(LABEL) {
        stage('Run Load Tests') {
          container('k6-container') {
            sh 'ls -al'
            sh 'k6 version'
            sh 'k6 cloud login --token TOKEN'
            sh 'k6 cloud script.js'
          }
        }
      }
    }

Has anyone else encountered this issue with the grafana/k6 image? How can I modify the pipeline to allow the execution of shell commands within the container? I would appreciate any insights or suggestions.
