“What is stopping you from” <- this is a loaded question.

We’ve been hosting stuff long before docker existed. Docker isn’t necessary. It is helpful sometimes, and even useful in some cases, but it is not a requirement.

I had no problems with dependencies, config, etc because I am familiar with just running stuff on servers across multiple OSs. I am used to the workflow. I am also used to docker and k8s, mind you - I’ve even worked at a company that made k8s controllers + operators, etc. I believe in the right tool for the right job, where “right” varies on a case-by-case basis.

tl;dr docker is not an absolute necessity and your phrasing makes it seem like it’s the only way of self‐hosting you are comfy with. People are and have been comfy with a ton of other things for a long time.
