| 22 📎 Hey there! It looks like you're trying to run a Docker daemon. | |
| 23 You probably should use the "dind" image variant instead, something like: | |
| 24 docker run --privileged --name some-overlay-docker -d docker:stable-dind --storage-driver=overlay | |
| 25 See https://hub.docker.com/_/docker/ for more documentation and usage examples. | |
