> Allow isolators to inject task-specific environment variables.
> --------------------------------------------------------------
>
> Key: MESOS-7429
> URL: https://issues.apache.org/jira/browse/MESOS-7429
> Project: Mesos
> Issue Type: Improvement
> Affects Versions: 1.2.0
> Reporter: Till Toenshoff
> Assignee: Till Toenshoff
> Labels: containerizer, isolator, mesosphere
> Fix For: 1.4.0
>
>
> For command tasks, we currently have no way for isolators to inject task specific environments into data path.
> Isolators in their {{prepare}} implementation can return a {{ContainerLaunchInfo}} which currently supports setting the member {{environment}} - but that is effective for the executor already and will get inherited by the task environment.
> Given that the command-executor is active in the host-fs context but the task may be running in a container-fs context ({{has_rootfs=true}}), using the above will possibly cause failures, depending on the nature of the variables set -- consider e.g. {{LD_LIBRARY_PATH}} as a fatal one.
> The command-executor does support the flag {{task_environment}} to receive environment variables which are meant exclusively for the task itself but not the executor.
> Runtime isolators (docker/runtime, appc/runtime) already make use of this flag. However, they do it in a way that is a bit unfortunate as it does not allow for other isolators to make use of it - there is no merging taking place in the containerizer.
