Build Environment Variables not available within Container Step

      Currently, inside the build container steps, shell executions cannot access build-level parameters, such as SCM properties or Build information like BUILD_NUMBER.

      A workaround to allow this is to redeclare it:

       

      environment{

      BUILD_NUMBER = "${BUILD_NUMBER}

      }

       

      But this should be fixed to allow smoother use of the Kubernetes Plugin

          Matthew Ludlum added a comment -

          An example build would be this:

           

          pipeline {
    agent {

        kubernetes{
                label 'openjdk'
                containerTemplate{
                        name 'openjdk'
                        image 'openjdk'
                        workingDir '/home/jenkins'
                        ttyEnabled true
                        command 'cat'
                        args ''
                }
        }
}


    stages{
        stage('Build') {
            steps {

                sh 'echo DEFAULT_BUILD_NUMBER: ${BUILD_NUMBER}'
                container('jnlp')
                {
                    sh 'echo JNLP_BUILD_NUMBER: ${BUILD_NUMBER}'
                }
                container('openjdk'){
                    sh 'echo OPENJDK_BUILD_NUMBER: ${BUILD_NUMBER}'
                }
            }
        }
    }
}

           Where the container steps do not show the BUILD NUMBER.
