      Attempting to execute sh command within container step fails when the image user is not root.

      Replicate by running pipeline:

      podTemplate(name: 'my-pod', label: 'my-pod',
  containers: [
    containerTemplate(name: 'kubectl-cmd', 
                      image: 'wernight/kubectl:1.6.4',
                      ttyEnabled: true, 
                      command: 'cat', args:null)]) {
      node('my-pod') {
        stage('Test command') {
          container('kubectl-cmd') {
            sh 'whoami'
          }
        }
      }
} 

      `sh 'whoami'` does not successfully run, and the job fails with message: "ERROR: script returned exit code -2 "

      The image being run is here.

      I created a modified version of the image where simply "User kubectl" is removed. The job then runs as expected.
