Jason Lai created MESOS-8257: -------------------------------- Summary: Unified Containerizer "leaks" a target container mount path to the host FS when the target resolves to an absolute path Key: MESOS-8257 URL: https://issues.apache.org/jira/browse/MESOS-8257 Project: Mesos Issue Type: Bug Components: containerization Reporter: Jason Lai Assignee: Jason Lai
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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
