It's not possible to invoke the docker containerizer from outside of Mesos, as far as I know.
If you persue this route, you can run into issues with orphaned containers as your executor may die for some unknown reason, and the container is still running. Recovering from this can be tricky business, so it's better if you can adapt your framework design to fit within the Mesos Task/Executor pattern. -- Tom Arnfeld Developer // DueDil (+44) 7525940046 25 Christopher Street, London, EC2A 2BS On Mon, Apr 6, 2015 at 7:00 PM, Vinod Kone <vinodk...@apache.org> wrote: > Tim, do you want answer this? > On Wed, Apr 1, 2015 at 7:27 AM, Tom Fordon <tom.for...@gmail.com> wrote: >> Hi.
