Given that Watchtower is potentially unmaintained now, this might be a cool alternative?

Features from their github:
- Extremely fast. Cup takes full advantage of your CPU and is hightly optimized, resulting in lightning fast speed. On my Raspberry Pi 5, it took 3.7 seconds for 58 images!
- Supports most registries, including Docker Hub, ghcr.io, Quay, lscr.io and even Gitea (or derivatives)
- Doesn't exhaust any rate limits. This is the original reason I created Cup. I feel that this feature is especially relevant now with Docker Hub reducing its pull limits for unauthenticated users.
- Beautiful CLI and web interface for checking on your containers any time.
- The binary is tiny! At the time of writing it's just 5.4 MB. No more pulling 100+ MB docker images for a such a simple program.
- JSON output for both the CLI and web interface so you can connect Cup to integrations. It's easy to parse and makes webhooks and pretty dashboards simple to set up!
There's a plugin for compose, but podman itself does have some differences here and there. I'm starting to migrate my own stuff as Docker is getting more money hungry. Womder if they'll try to IPO in a few years. Seems like that's what these kinds of companies do after they start to decline from alienating users. Just wish that portainer and docker hadn't killed all the GUIs for docker and swarm was better supported.
The company i work for has also required us to migrate from Docker as the hub and desktop app are no longer totally free. I expect more and more limitations will show up on the free versions as usually is the case with companies like this.
I hate what I'm reading here... But I have already thought about the possible enshitification of docker and docker-compose...
It really sucks to always have to relearn everything from the beginning... Now that I feel comfortable I have to relearn a new way to keep my homelab up and running.
Kinda understand how Plex people feel when someone tells them to switch over to jellyfin...Can't wait to see Jellyfin or Arr stack going a similar route 😮💨😮💨!
Edit: Similar feeling goes toward Traefik... 😕🫤
Let me stop you right there: the chances of Jellyfin going rogue are much smaller. It's libre software. It's GPL. It's copyleft. We are pretty much safe.
I really hope you're right :/ !!
Yeah I saw that plugin a few years ago and it was not ready for production yet.
I am going a whole different route, but have the same motivation: get rid of docker and improve the security.
I will move from docker compose to Nomad. And I will also not use containers itself anymore. I want/need more security. You can achieve this with MicroVM (Firecracker). However, you would need to build those VM images yourself. But there is a solution to it. Kata-containers. They allow to deploy OCI compliant containers into seperate MicroVM’s. Then you have true isolation from the host kernel, while not losing much of start-up time.
What i read here is concerning. Non that i was getting into the swing of drocker .... :-( Is LXC the future then?
Docker uses LXC. LXC is actually at the core of many container engines.
