             Summary: Provide user namespaces for privileged access inside containers
                 Key: MESOS-2952
                 URL: https://issues.apache.org/jira/browse/MESOS-2952
             Project: Mesos
          Issue Type: Bug
            Reporter: Paul Brett
            Assignee: Paul Brett


User namespaces allow per-namespace mappings of user and group IDs. This means that a process's user and group IDs inside a user namespace can be different from its IDs outside of the namespace. Most notably, a process can have a nonzero user ID outside a namespace while at the same time having a user ID of zero inside the namespace; in other words, the process is unprivileged for operations outside the user namespace but has root privileges inside the namespace.
