Mike Babineau updated MESOS-2374:
---------------------------------
Description:
There is no convenient way to mount sandbox subdirectories (such as unpacked
archives from fetched URIs) as container volumes.
While it is possible to access sandbox subdirectories via $MESOS_SANDBOX, this
presumes the container is expecting $MESOS_SANDBOX to be passed in.
Furthermore, it also expects 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.
One potential solution:
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).
was:
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:
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).
