Docker workflow plugin and env vars

[Sascha Schwarz]

Hi all.

Env vars being set to the same value in global Jenkins config and

docker host are being removed from the environment of started containers.

This just struck me with proxy settings.

E.g. set

http_proxy=http://foo.example.com

in global Jenkins config and on a node running docker (envvartesthost below).

Now with following pipeline assert that http_proxy is not showing up.

pipeline {
    agent {
        docker {
            image "busybox"
            label "envvartesthost"
        }
    }
    stages {
       stage ("envvartest") {
           steps {
               sh "env"
           }
       }
    }
}  

Does anyone know the ratio behind this?

TIA

Sascha
