I wish GitLab could be a bit lighter weight as well. I'd love to spin up the cheapest VM instance I can find on a cloud provider, pull a Docker container, and have a working GitLab instance up and running, but they "strongly advise against" running GitLab at the amount of memory those cheap VMs usually come with (usually around 512MB) [1].
