Mike Babineau updated MESOS-2374:
---------------------------------
Summary: Support relative host paths for container volumes (was: Support
relative hostPaths for container volumes)
> Support relative host paths for container volumes
> -------------------------------------------------
>
> Key: MESOS-2374
> URL: https://issues.apache.org/jira/browse/MESOS-2374
> Project: Mesos
> Issue Type: Improvement
> Components: containerization, docker
> Affects Versions: 0.21.1
> Reporter: Mike Babineau
>
> There is no convenient way to mount directories within the sandbox as
> container volumes.
> A common use case is injecting the contents of one or more fetched-URI
> archives, each of which needs to be extracted and mounted inside the
> container.
> While it is possible to access sandbox subdirectories via $MESOS_SANDBOX,
> this presumes the container already knows the resulting subdirectory paths.
> Unfortunately, since the archives are extracted by the fetcher, operators can
> not control these paths. Path changes to the extracted archive must be
> accompanied by a container image change. Furthermore, the container must be
> aware of $MESOS_SANDBOX to be able to use the access these files at all.
> One potential solution is to add support for relative paths to the
> containerizer: if the containerizer is given a relative host path, it simply
> prepends the sandbox path before passing it to Docker (or similar).
