             Summary: Add support for tmpfs mounts with the Docker runtime
                 Key: YARN-8642
                 URL: https://issues.apache.org/jira/browse/YARN-8642
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Shane Kumpf


Add support to the existing Docker runtime to allow the user to request tmpfs mounts for their containers. For example:
{code}/usr/bin/docker run --name=container_name --tmpfs /run image /bootstrap/start-systemd
{code}

One use case is to allow systemd to run as PID 1 in a non-privileged container, /run is expected to be a tmpfs mount in the container for that to work.
