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

> docker containerizer should override entrypoint when starting executor.
> -----------------------------------------------------------------------
>
> Key: MESOS-1761
> URL: https://issues.apache.org/jira/browse/MESOS-1761
> Project: Mesos
> Issue Type: Bug
> Components: containerization
> Reporter: Jay Buffington
> Assignee: Timothy Chen
> Labels: docker
> Fix For: 0.20.1
>
>
> When I specify an ExecutorInfo with a ContainerInfo set, the docker
> containerizer will do {{docker run ... /bin/sh -c ./my-executor}}.
> If the docker image the user specifies has an entrypoint configured the
> executor command will be appended to the entrypoint rather than overwriting
> it. The docker docs says:
> {quote}
> Unlike the behavior of the CMD instruction, The ENTRYPOINT instruction adds
> an entry command that will not be overwritten when arguments are passed to
> docker run. This allows arguments to be passed to the entry point, i.e.
> docker run <image> -d will pass the -d argument to the entry point.
> {quote}
> This results in docker running the entrypoint inside the container with the
> executorinfo's command as an argument. If you specified an executor this is
> never what you want.
> I suggest docker run use {{--entrypoint}} when starting an executor inside
> the container.
