Marco Massenzio updated MESOS-3836:
-----------------------------------
Assignee: Jojy Varghese (was: Marco Massenzio)
> `--executor-environment-variables` may not apply to docker containers
> ---------------------------------------------------------------------
>
> Key: MESOS-3836
> URL: https://issues.apache.org/jira/browse/MESOS-3836
> Project: Mesos
> Issue Type: Bug
> Components: containerization, slave
> Affects Versions: 0.25.0
> Environment: Mesos 0.25.0 configured with
> --executor-environment-variables
> Reporter: Cody Maloney
> Assignee: Jojy Varghese
> Priority: Minor
> Labels: mesosphere
>
> In our use case we set {{PATH}} as part of the
> {{\-\-executor_environment_variables}} in order to limit what binaries all
> tasks which are launched via Mesos have readily available to them, making it
> much harder for people launching tasks on mesos to accidentally depend on
> something which isn't part of the "guaranteed" environment / platform.
> Docker containers can be used as executors, and have a fully isolated
> filesystem. For executors which run in docker containers setting {{PATH}} to
> our path on the host filesystem may potentially break the docker container.
> The previous code of only copying across environment variables when
> {{includeOsEnvironment}} is set dealt with this
> (https://github.com/apache/mesos/blob/56510afe149758a69a5a714dfaab16111dd0d9c3/src/slave/containerizer/containerizer.cpp#L267)
> if {{includeOsEnvironment}} is set than we should copy across the current
> {{\-\-executor_environment_variables}}. If it isn't, then
> {{\-\-executor_environment_variables}} shouldn't be used at all.
> Another option which could be useful is to make it so that there are two sets
> of "Executor Environment Variables". One for when {{includeOsEnvironment}} is
> set, and one for when it is not.
