Subject [jira] [Commented] (AURORA-633) Support running Docker containers
Date Fri, 01 Aug 2014 22:25:38 GMT

    [ https://issues.apache.org/jira/browse/AURORA-633?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14083067#comment-14083067
] 

Jay Buffington commented on AURORA-633:
---------------------------------------

[~tarnfeld], yes, absolutely.  That's why I called the field {{container}} rather than {{docker}}.

> Mesos 0.20 will be released soon, and it will likely include support for a docker containerizer.
 See MESOS-1524.
> To make use of this feature, I propose modifying aurora's DSL to support running docker
containers both with and without the aurora executor.
> Task would be changed to introduce a container field and make processes optional when
a container is specified.  A Task to launch a Docker container using the entry point (aka
command) specified in the container would look like this:
> {noformat}
> Task(
>     name="my-task",
>     container=Docker(
>         image="docker:///centos:6u5',
>     ),
>     resources=Resources(cpu=1, disk=10*GB, ram=1*GB)
> )
> {noformat}
> If you specify processes in your Task then the docker containerizer will fetch and launch
the aurora executor for you.  This would run {{process_a}} then {{process_b}} inside the same
docker container using the aurora executor:
> {noformat}
> Task(
>     name="my-task",
>     container=Docker(
>         image="docker:///centos:6u5',
>     ),
>     processes=[process_a, process_b],
>     constraints=order(process_a, process_b),
>     resources=Resources(cpu=1, disk=10*GB, ram=1*GB)
> )
> {noformat}
> The Docker() struct would closely model the fields that will be in the DockerInfo protobuf
