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.

Selfhosting GitLab? (sh.itjust.works)

I’ve started building a small decentralized, non commercial app with a Rust backend + Node.js frontend running on k8s. I would have my own dedicated server for this. Just mentioning the setup because it might grow and for git there seem to be only GitHub and GitLab around and I prefer GitLab.

I care a lot about security and was wondering if it makes sense to self-host GitLab. I‘m not afraid of doing it, but after setup it shouldn’t take more than 1-2 hours per week for me to maintain it in the long run and I’m wondering if that’s realistic.

Would love to hear about the experience of people who did what I’m planning to do.

EDIT: Thanks for all the answers, trying my best to reply. I want CI/CD, container registry and secrets management that's what I was hoping to get out of GitLab.

Incoming wall of text

Here is my install script to set up Ubuntu since it has a bit of extra steps for privileged ports https://gitlab.meme.beer/-/snippets/1

Docker compose example, note that my config has a shared network with containers in another compose called nginx to keep traffic inside docker.
