If you are using Docker-in-Docker, you may want to checkout the new Sysbox runtime (find it on Github). It's a new type of runc that sits below Docker and creates rootless containers capable of running Docker, systemd, K8s, etc. All you have to do is "docker run --runtime=sysbox-runc" <some-image-with-docker> and you'll get a docker daemon that is fully isolated from the host. It's a great way of avoiding privileged containers or mounts to the host docker socket.
