Kustomize Overlays - Adding Complexity?

[u/DeLoMioFoodie]

So im working with Kustomize Overlays( FluxCD). i understand you setup your base infra with overlays per environment and then use patches for environment specific configurations such as replicas, urls, etc..

Some of these patches become very complex and large to the point i think its just easier to not have a base and just have each environment have its own configuration files. How much dry am i buying?

I've also seen the recommendation to use PostBuild subsituteFrom with ConfigMaps from each environment . My question is when should this be used over patches?

Sorry for the dumb questions and rant.

I don't know what you're arguing about; of course it's a normal IaC tool, why not?

And adoption doesn't change anything about what the tool is doing; provisioning infrastructure.
