This is super helpful and looks to be exactly what I am needing and looking for. I was really close on the right path, just realized one of my sources of pain is that I was editing the elasticsearch.yaml file, saving it and it was never actually applying the changes. I am using lens to view the file, I paste my yaml in, hit save, it says it saves successfully but I go back in and it is gone. I am wondering if its because the elasticsearch was installed with CRD and some how that has a definition that keeps overwriting my change?
