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.

    I run GitLab with docker compose and watchtower, all the updates are automated and have never caused any issues for me.

    That being said my setup uses about 7-8gb of ram.

        The VM is a 6 thread 16gb

        OS is currently Ubuntu 22.04.5 LTS (cloud image which is lightweight) just running a very simple docker engine install using the script (plus a few other options since I script the install)

        The load averages as of this current moment are 0.12, 0.15, 0.10 so not even a full thread is being used.

        I let the container run unmetered on the CPU and memory.

        I can provide both the compose and my install script (which is on the GitLab instance) if you are curious.

          Thanks! Super helpful and I’d love to have the compose and install script. I also looked into the Helm charts but still wondering if I should go down that route or not eventually.
