-----------------------------------
Summary: Docker with command shell=true should override entrypoint
Key: MESOS-1770
URL: https://issues.apache.org/jira/browse/MESOS-1770
Project: Mesos
Issue Type: Improvement
Reporter: Timothy Chen
Assignee: Timothy Chen
Currently with the new CommandInfo there is a shell flag that if it's enabled,
will wrap the command with /bin/sh -c with docker run.
However we don't override the entrypoint, therefore when a user specified a
image with a entrypoint and also have shell=true then /bin/sh -c will become
part of the argument to the entrypoint.
I don't think there is any example where users expect /bin/sh -c to be a
argument in the entrypoint, and to make sure cases where shell is needed for
expanding environment variables we also override the entrypoint.
