---------------------------------
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.
