Yep. This will cruise along longer than the parent's solution, but when it breaks, you'll be starting over all of the original services from scratch plus the management system you had built once to manage them.
But it only breaks when all systems fail together; if your router fails, you can rebuild it from the gitlab job. If the VM host fails, you have time to replace it because the rest of your network still functions. If your git host fails, same thing, but where did you put those backups?
