Feeling like a computer God...
I have made a Dockerfile and automated a Docker Linux and #Bitcoin Core installation, and connected sparrow wallet from the host to the container.

Docker requires root. Never run untrusted codr with root permission, especially on your Bitcoin setup. Podman is a dropin replacement for Docker which does not require a daemon and supports rootless containers.
$ sudo apt remove *docker*
$ sudo apt install podman
$ alias docker=podman
Good work, Parman.
