# 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 ...

# Specify Intel x86-64 VM
# arch: "x86_64"

# CPUs (Default: 4)
cpus: 4

# Memory size (Default: "4GiB")
memory: "8GiB"

# Disk size (Default: "100GiB")
# disk: "100GiB"

# This example requires Lima v0.8.0 or later
images:
# Hint: run `limactl prune` to invalidate the "current" cache
