Procedure to make the Datadog Agent Supervisor run as dd-agent instead of root. The main issue is file permission. I moved lock, pid and sock to /tmp to ensure it works well. Any other directory with rw permission for the user dd-agent would make it.

• Stop the Agent. service datadog-agent stop
• Be sure that all processes are stopped and the pid/sock got removed
  • Check ps aux | grep -v grep | grep datadog should be empty
  • Remove /var/run/datadog-supervisord.pid, /var/tmp/datadog-supervisor.sock, /var/lock/subsys/datadog-agent.
• Give permission to dd-agent to the supervisor log file.
  • Run chown dd-agent:dd-agent /var/log/datadog/supervisord.log
• Update the init script and the supervisor configuration to put files in tmp.

# Run a Varnish container to test this
# I had to hack TERM=xterm otherwise "varnishstat" would not work

docker run -d -P -h "my_varnish" --name "my_varnish_container" -e TERM=xterm vbatts/fedora-varnish

# "my_varnish_container" is used as container name in docker_varnishstat.
