Subject Re: Problem getting docker container running
Date Fri, 13 Mar 2015 16:54:58 GMT
When the task launches, a sandbox directory is created, in the above e-mail
it
was /tmp/mesos/slaves/20150313-131712-1143806393-5050-6-S0/frameworks/20150306-112428-1177360825-5050-6-0000/executors/thermos-1426253925515-docker-test-devel-hello_docker-0-a9011a74-c2a2-4cb7-b402-d383fde58c41/runs/e53d1267-e341-46f5-9759-0361c7440781.
Is there anything else in that directory?  Please post anything logs you
find in there as they may provide useful clues.

Possibly unrelated, your slave work directory is /tmp.  I have observed
that some environments a temp cleaner process runs that automatically
deletes things under here.  This may not fix the issue at hand here, but i
suggest you move this outside /tmp as it is critical state for the slave.
