Hi,

I have a declarative pipeline, where the pod contains a few containers, during the execution I want to specify where to run a particular step, so I use the container() step. When I declare an environment variable that contains '$' as value and try to use it in the container step the '$' is doubled.

I originally noticed this with the credential-binding plugin, but I figured that it can be reproduced with simply using environment variables.

I've created a simple pipeline to demonstrate:

pipeline {
    agent any
    environment {
        FRUIT = '$apple'
    }
    stages {
        stage("Test") {
            steps{
                sh 'echo "${FRUIT}"'
                container('jnlp') {
                    sh 'echo "${FRUIT}"'
                }
            }
        }
    }
}

Result:

[Pipeline] stage
[Pipeline] { (Test)
[Pipeline] sh
+ echo $apple
$apple
[Pipeline] container
[Pipeline] {
[Pipeline] sh
+ echo $$apple
$$apple
