A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

GitHub - sergi0g/cup: 🥤Docker container updates made easy (github.com)

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

Screenshot:

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!

Gitea (or derivatives)

So also codeberg/forgejo?

I'm currently on WUD (what's up docker) which has some great functionality like custom templates to link to the actual release note.

Does cup allow similar thing? How does it compare to WUD if you have tested both ?

Edit:

Thanks to What's up Docker? for inspiring this project.

Ohhh yeah okay... So I will stay on WUD and keep an eye on cup in case WUD goes unmaintained !
