		📎 Hey there!  It looks like you're trying to run a Docker daemon.
		   You probably should use the "dind" image variant instead, something like:
		     docker run --privileged --name some-overlay-docker -d docker:stable-dind --storage-driver=overlay
		   See https://hub.docker.com/_/docker/ for more documentation and usage examples.
