------------------------------------
Summary: Duplicate name-value env-vars in '-e' option of docker run
Key: MESOS-2882
URL: https://issues.apache.org/jira/browse/MESOS-2882
Project: Mesos
Issue Type: Bug
Components: docker
Affects Versions: 0.22.1
Reporter: Anindya Sinha
Priority: Minor
docker run provides the option '-e' to pass environment variables.
In src/docker/docker.cpp->Docker::run(), environment vars are picked up from
passed in 'env' as well as from 'commandInfo.environment().variables()'.
But with git hash 391e72b9 (https://reviews.apache.org/r/31889, MESOS-2463),
'env' is already populated with variables() [see
src/containerizer/containerizer.cpp->executorEnvironment()] as a result of
which env vars are duplicated (the ones in Environment::Variable) in the docker
run command.
