I maintain a small document in Github outlining the GitOps standards I use in my own repositories. I find with kustomize it’s very important to have a standardized layout in terms of folder structure in an organization or else it becomes challenging for everyone to understand what kustomize is doing. A common frame of reference makes all the difference.
I’ve recently tweaked my standards, feel free to check them out at https://github.com/gnunn-gitops/standards. Comments always welcome as I’m very interested in learning what other folks are doing.
