Selfhosting GitLab?

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.
