Gitlab Self Hosted + Tailscale

Explored how to deploy a self-hosted GitLab Omnibus instance on a Debian VM using UTM, then securely expose it beyond my local network with Tailscale instead of a public IP or domain. This guide walks through VM provisioning, OS hardening, and GitLab installation, showing how a private overlay network can replace traditional firewall port-forwarding for remote access.
