Wrap podman up to make it work a little more like docker

To install:

pip install -e .

This will install a script called docker. You want to ensure that it's first on your path, ahead of the docker executable.

To use:

Enabling sshd

First, you need to ensure you've got sshd enabled on your Mac:

• open the "System Preferences" panel

• select the "Sharing" group:

  

• activate "Remote Login":

  

• select "only these users":

  

• Hit the "+" button and add yourself.

Installing and configuring podman

This uses the installation that is supplied by brew:

brew install podman
podman machine init --cpus 4 --disk-size 50 --memory 8192
podman machine start

Setting up the sshfs reverse tunnel

Use the supplied script:

podman-mount-shim

This script will not exit; you can ^C out of it when you're done. It sets up an ssh connection to the podman machine, over which an sshfs connection is tunneled back to the Mac. Fair warning: your entire home directory is then mounted using this into the podman VM.

Tell the docker shim script to prefer to use podman

docker use podman

Try it

docker run -ti --rm -v $HOME/src:/src oraclelinux:7-slim

The script intercepts -v flags and (crudely) rewrites them to point at the sshfs-mounted directory.

... and that's it. Be warned: this is decidedly alpha quality.

What you don't get

There's no docker-compose support (because I don't use it) - or anything else, for that matter. Seriously; it's just a ten-minute drive-by.
