Mesos-slave not picking up attributes I am running a x-mesos-slave container with these attributes:

"Cmd": [
    "--attributes=farm:app,region:eu-west-1,zone:eu-west-1b"
],


When I run an application in Marathon with farm:UNIQUE, this works fine.

However when I try to use zone:UNIQUE, the application gets stuck in waiting.

This makes it seem there is no region/zone configured.
As per https://mesos.readthedocs.io/en/0.22.2/attributes-resources/ states, attributes are separated by ';' not by ','.
