Timothy Chen commented on MESOS-2364:
-------------------------------------
This seems to warrent a bigger discussion as this changes the behavior for
everyone. I originally made the change so that it's matching the behavior of
the docker cli itself, and have suggestions from the docker team to avoid
pulling each time.
With this change it is no longer an option to even used a cached version of
latest and registry needs to up all the time.
I personally cannot argue for each way, but I'm imagining someone will.
> Docker containerizer should pull every time if image tag is ":latest"

> The "latest" tag for a docker image denominates the newest or most recent
> version of a docker image. So the docker containerizer should pull every time
> from the registry if the "latest" tag is encountered to ensure that the most
> recent version is used.
