Lima/Podman configuration allowing connections to ports 80, 443 through non-loopback interfaces
# Based on https://github.com/lima-vm/lima/blob/943c90b13e38be32777b8f25be17c2491bb1421f/examples/podman.yaml
#
# Allows connections to ports 80, 443 through non-loopback interfaces.
# 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')
