You'd still be able to compose a bunch of containers together, but it would result in a new, single container due to nesting.

It could even be compatible with docker-compose and it's yaml.

I enjoyed docker compose as well (enough to use it for PhotoStructure), but was bit by breaking changes even when I had specified a version in my docker-compose.yml.

It meant that a bunch of my beta users suddenly had broken PhotoStructure configurations because their docker-compose implementation had received a minor update. Why require a version to your configuration file and not increment it on breaking changes?

I ended up tearing out the script that helped people create their own docker-compose.yml file, and replaced the installation instructions with an annotated call to `docker run`.

And don't get me started on how janky it is to update existing containers to new images without docker-compose: there seems to only be one third-party tool to assist with this automatically (lighthouse), but is essentially abandoned. I'd love to be wrong about this, please point me to other solutions if they exist!

I use watchtower with docker compose and the update is seamless.

Haven’t used Podman in production but at home it’s a huge improvement over Docker and enjoyable to use
