To use the docker command inside a Docker container, use the docker image and mount the /var/run/docker.sock socket as a volume.

docker run --rm -it -v /var/run/docker.sock:/var/run/docker.sock docker

Alternatively, use the docker:dind image with the --privileged flag. (This method is not recommended)

docker run --privileged -d docker:dind
