Docker with docker-compose for lima-vm

bash.sh

# now you can do
# alias docker="limactl shell docker docker"
# and run
# docker run --rm ubuntu
# port forwarding and volume mounting would work out out of the box
# docker run --rm -p 8080:80 -v `pwd`:/usr/share/nginx/html nginx

docker.yaml

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

# Hint: To allow `docker` CLI on the host to connect to the Docker daemon running inside the guest,
# add `NoHostAuthenticationForLocalhost yes` in ~/.ssh/config , and then run the following commands:
# $ export DOCKER_HOST=ssh://localhost:60006
# $ docker ...

# If ssh:// ... does not work, try the following commands:
# $ ssh -f -N -p 60006 -i ~/.lima/_config/user -o NoHostAuthenticationForLocalhost=yes -L $HOME/docker.sock:/run/user/$(id -u)/docker.sock 127.0.0.1
# $ export DOCKER_HOST=unix://$HOME/docker.sock
# $ docker ...

  # Hint: run `limactl prune` to invalidate the "current" cache
