`docker run` flags. Because the user must be part of the docker group in order
to access `/var/run/docker.sock`, root access is required if {beatname_uc} is
running as non-root inside the container.

If Docker daemon is restarted the mounted socket will become invalid and metadata
will stop working, in these situations there are two options:

- Restart {beatname_uc} every time Docker is restarted
- Mount the entire `/var/run` directory (instead of just the socket)
