Subject [jira] [Created] (MESOS-8895) Document known differences between Docker and Mesos containerizers
Date Tue, 08 May 2018 15:21:00 GMT
Greg Mann created MESOS-8895:
--------------------------------

             Summary: Document known differences between Docker and Mesos containerizers
                 Key: MESOS-8895
                 URL: https://issues.apache.org/jira/browse/MESOS-8895
             Project: Mesos
          Issue Type: Bug
          Components: containerization, documentation
            Reporter: Greg Mann


To help developers who create applications which may be run using both the Docker and Mesos
containerizers, we should document all known differences from a developer's perspective.

For example:
* By default, Docker starts the task process in {{/}} while Mesos containerizer starts the
task process in the Mesos task sandbox.
* When {{command.shell}} is {{false}}, Mesos containerizer launches the command via {{execvp}}
while Docker passes the command as arguments to the Docker CLI. One difference this causes
is that {{$@}} will be empty when the Mesos containerizer is used and the executable is a
bash script.
