Docker in Docker is not a waste of resources, they just make the same container runtime the container is running on available to it. Really a better solution than a control plane like Kubernetes.
Aren't you describing docker-out-of-docker rather than docker-in-docker?
No, you're running docker inside a docker container. The container provides a docker daemon that just forwards the connection to the same runtime. It's not running two dockers, but you are still running docker inside docker.

Docker is not emulation so there's no waste of resources.
Doesn't podman get around a lot of those issues?
Aw hell, more band-aids because people don't want to get software distribution done right.
Can we please go back to the days of sudo dpkg -i foo.deb and then just /usr/bin/foo ?
I am still using "ar x" and "tar xvf" for .deb files on Void Linux, because some projects only release .deb files!
I normally hate things shipped as containers because I often want to use it inside a docker container and docker-in-docker just seems like a messy waste of resources.
