Environment variables in docker agent args (pipeline)

[Antoine Cotten]

Hi Jenkins experts,

My first experiment with the Pipeline plugin was to execute a build step inside a Docker container, configured as agent, but I'm unable to use Jenkins' standard variables in my agent configuration.

With the following code I'm trying to mount the current workspace to a specific destination:



stages {
  stage('Build') {
    agent {
      docker {
        image 'golang:1.9'
        args '-v $WORKSPACE:/go/src/github.com/foo/bar'
    }
  }
}

This simply doesn't work, the target directory is created by Docker but remains empty, although my workspace does contain the code pulled from my SCM.

Any tips?

Thanks!
