GitOps is just like "DevOps" -- you don't really know what it means to a specific org until you talk to them, because people interpret it differently based on their own understanding (or if they have a horse in this race).

To me it always means describing the desired state of your infra in structured data, storing that in git, and run controller to reconcile it against the actual infra.

If your GitOps engine has to compile/run the "code" to uncover the desired state, that defeats the purpose of GitOps and is no better than running your hand crafted release bash script in a CI/CD pipeline.

It should have never been called infra-as-code, but infra-as-data.

This does not change my statement at all though? You fundamentally can't really predict the impact of some changes in a given environment until it's deployed. Just because you can obtain the current state of the environment and reconcile some stuff doesn't change this.

That's why you should call what you store in git the _desired_ state, not anything else. A git repository is not a live database. It's a collection of static text files that change less often than your live system. There will be bugs and misconfiguration, and sometimes the desired state is just technically not reachable, and that's fine. What the actual state is doesn't matter. Leave that to the controller. State drifting is a problem your gitops engine should detect, and should be fixed by the owner of controller code.

Some companies practice infra-as-code, point to their git repo and tell me "this is our single source of truth" of our infrastructure. And I have to tell them that statement is wrong.

This is correct. You need some kind of running check on the environment and when possible code that handle exceptional cases.

Sometimes that's as simple as a service that shoots other services in the head to restart them. Othertimes it's more complicated. But lot's of places can't afford to get more complicated than "alert a human and have them look at it".
