      I found a bug that doesn't let me set the company proxy inside a docker container because it is defined on the host as well.

      environment variable on the host:

      https_proxy=mycompany.de:8080

       

      pipeline {
    agent {
        label 'master'
    }
    stages {
        stage('Azure Docker Image Build') {
            steps {
                withDockerContainer('microsoft/azure-cli') {
                    withEnv(['HTTPS_PROXY=mycompany.de:8080']) {
                        sh 'env'
                    }
                }
            }
        }
    }
}

      I think the origin of this bug is this line: https://github.com/jenkinsci/docker-workflow-plugin/blob/648f335899c5229fb8a6e889739db9cfb15de890/src/main/java/org/jenkinsci/plugins/docker/workflow/WithContainerStep.java#L130

      Where every enivronment variable that matches the host variables is removed.

      Currently the workaround is to explicitly set the environment variable:

      withDockerContainer(args: '-e HTTPS_PROXY=mycompany.de:8080', image: 'microsoft/azure-cli') {
    // some block
}
