Guangya Liu commented on MESOS-5389:
------------------------------------
I think that for docker containerizer, we should keep the behaviour same as
docker, the {{man docker run}} will report the following:
{code}
-v|--volume[=[[HOST-DIR:]CONTAINER-DIR[:OPTIONS]]]
Create a bind mount. If you specify, -v /HOST-DIR:/CONTAINER-DIR,
Docker
bind mounts /HOST-DIR in the host to /CONTAINER-DIR in the Docker
container. If 'HOST-DIR' is omitted, Docker automatically creates
the new
volume on the host. The OPTIONS are a comma delimited list and can
be:
0
item [rw|ro] item [z|Z] item [[r]shared|[r]slave|[r]private] item
[nocopy]
The CONTAINER-DIR must be an absolute path such as /src/docs. The
HOST-DIR can be an absolute path or a name value. A name value must start with
an alphanumeric character, followed by
a-z0-9, _ (underscore), . (period) or - (hyphen). An absolute path
starts with a / (forward slash).
{code}
It highlight that the {{The CONTAINER-DIR must be an absolute path such
as /src/docs. }}.
> docker containerizer should prefix relative volume.container_path values with
> the path to the sandbox

> Project: Mesos
> Issue Type: Bug
> Reporter: James DeFelice
> Labels: docker, mesosphere, storage, volumes
>
> docker containerizer currently requires absolute paths for values of
> volume.container_path. this is inconsistent with the mesos containerizer
> which requires relative container_path. it makes for a confusing API. both at
> the Mesos level as well as at the Marathon level.
> ideally the docker containerizer would allow a framework to specify a
> relative path for volume.container_path and in such cases automatically
> convert it to an absolute path by prepending the sandbox directory to it.
