> Unified Containerizer "leaks" a target container mount path to the host FS

> Key: MESOS-8257
> URL: https://issues.apache.org/jira/browse/MESOS-8257
> Project: Mesos
> Issue Type: Bug
> Components: containerization
> Affects Versions: 1.3.1, 1.4.1, 1.5.0
> Reporter: Jason Lai
> Assignee: Jason Lai
> Priority: Critical
> Labels: bug, containerizer, mountpath
>
> If a target path under the root FS provisioned from an image resolves to an
> absolute path, it will not appear in the container root FS after
> {{pivot_root(2)}} is called.
> A typical example is that when the target path is under {{/var/run}} (e.g.
> {{/var/run/some-dir}}), which is usually a symlink to an absolute path of
> {{/run}} in Debian images, the target path will get resolved as and created
> at {{/run/some-dir}} in the host root FS, after the container root FS gets
> provisioned. The target path will get unmounted after {{pivot_root(2)}} as it
> is part of the old root (host FS).
> A workaround is to use {{/run}} instead of {{/var/run}}, but absolute
> symlinks need to be resolved within the scope of the container root FS path.
