# Example to use Podman instead of containerd & nerdctl
# $ limactl start ./podman.yaml
# $ limactl shell podman podman run -it -v $HOME:$HOME --rm docker.io/library/alpine
# To run `podman` on the host (assumes podman-remote is installed):
# $ export CONTAINER_HOST=$(limactl list podman --format 'unix://{{.Dir}}/sock/podman.sock')
# $ podman --remote ...
# To run `docker` on the host (assumes docker-cli is installed):
# $ export DOCKER_HOST=$(limactl list podman --format 'unix://{{.Dir}}/sock/podman.sock')
# $ docker ...
# This example requires Lima v0.8.0 or later
