--------------------------------------

             Summary: docker isolator does not overwrite Dockerfile ENV
                 Key: MESOS-6057
                 URL: https://issues.apache.org/jira/browse/MESOS-6057
             Project: Mesos
          Issue Type: Bug
          Components: containerization
    Affects Versions: 1.0.0, 1.0.1, 1.1.0
            Reporter: Stéphane Cottin


The docker/runtime isolator does not overwrite env values when a default value is present in the Dockerfile.

Steps to reproduce : 

{code}
mesos-execute --master=leader.mesos:5050 --name=test --docker_image=bashell/alpine-bash --env="{\"LC_ALL\": \fr_FR.UTF-8\",\"LC_TEST\": \"fr_FR.UTF-8\"}" --command="env"
{code}

outputs in stdout :

{code}
[...]
LC_ALL=en_US.UTF-8
LC_TEST=fr_FR.UTF-8
[...]
{code}
 
{{en_US.UTF-8}} is the default value from the dockerfile, see https://hub.docker.com/r/bashell/alpine-bash/~/dockerfile/
