Hi,

I just wanted to leave some notes as I recently invested quite some time to get the new docker 20.10 running. (Ubuntu 22.04 image for example won't build on older docker versions)
The trick is to use gitlab's docker machine here: https://gitlab.com/gitlab-org/ci-cd/docker-machine
(The original docker machine is in maintenance mode and the guys from docker refuse to fix the issue for docker 20.10)

Then you can get rid of this MachineOptions engine-install-url parameter , or upgrade it to:

MachineOptions = [
     "engine-install-url=https://releases.rancher.com/install-docker/20.10.12.sh",
]
