You started a thread here explicitly asking for docker compose files that work on podman, but implicitly you want files that don’t have your particular issues. What issue are you having? It could be that it’s a setup/config issue and not a compose problem. Podman is specifically compatible with rocker and its tools, where I’ve seen people just alias docker to podman on their systems and keep working.
I doubt that all of your containers are all having unique problems. So sharing one or two of the common blockers, and how you have tried to work around them, would help a lot in what kinds of compose files you are looking for.
For instance, can you run a compose that is just a single Redis container? Just share it here, help us help you.
Kinda. You can copy your snapshots from @home too, meaning a restore from backup also restores your local file version history. There are also tools to push snapshots around as a large archive instead of dealing with smaller files directly.
The COW can also reduce the chances of running rsync on a large file that is currently being accessed, and getting a partial file in your backup. Or I suck at rsync 🤷♂️
