I need a Debian container that can run containers itself (and has access to systemd). Following this post, I have tried to run
docker run -v /var/run/docker.sock:/var/run/docker.sock --name debian-buster-slim -h 10-slim -e LANG=C.UTF-8 -it debian:10-slim /bin/bash -l
but the container cannot run docker containers. What am I doing wrong?
