Description

I created and launched a container successfully in chronos, but when mesos ran the docker container, docker did not accept the volumes setting due to the colon in the executor id (-v option). Here is the executor id, which is valid: ct:1411670160000:0:lldocker.

In mesos, there will be a fix to avoid using the host directory by use of a simlink and mapping. However, ideally docker will fix this issue. They should accept executor ids with colons as the format is valid.

Here is the error log:
