Run docker-rootful on Lima

docker-rootful.yaml

# Example to use Docker instead of containerd & nerdctl
# $ limactl start ./docker.yaml
# $ limactl shell docker docker run -it -v $HOME:$HOME --rm alpine

# To run `docker` on the host (assumes docker-cli is installed):
# $ export DOCKER_HOST=$(limactl list docker --format 'unix://{{.Dir}}/sock/docker.sock')
# $ docker ...

# This example requires Lima v0.8.0 or later
images:
# Try to use release-yyyyMMdd image if available. Note that release-yyyyMMdd will be removed after several months.

  To run `docker` on the host (assumes docker-cli is installed), run the following commands:
  ------
  docker context create lima --docker "host=unix://{{.Dir}}/sock/docker.sock"
  docker context use lima
  docker run hello-world
  ------

Nach der Installation in der lima shell:

sudo usermod -aG docker $USER

Danach lima neustarten und Spaß haben!
