Guangya Liu commented on MESOS-4896:
------------------------------------

It would be great to have this merged in 0.29 as this can help improve the usability when end user using docker as image provider with mesos containerizer. cc [~jieyu] , [~gilbert]

> Currently, when using DOCKER as image provider but not enabling docker/runtime, the agent will exit with a message: 
> {code}
> EXIT(1)
>       << "Docker runtime isolator has to be specified if 'DOCKER' is included "
>       << "in 'image_providers'. Please add 'docker/runtime' to '--isolation' "
>       << "flags";
> {code}
> This will bring some trouble to operator cause s/he needs some manual operations, it is better to enable agent to add this isolator dynamically based on image provider.
