Apologies for this slightly off -topic post, but I know many of you are dipping into into more of the cloud platform, including Kubernetes, so I though this might be of interest to some, Especially since Elasticsearch makes a great companion for Apps Script - I'll post about this later so if you are interested in following that, this is a godd start and pre-req.
This is an example of getting a complex stateful app up and running (in this case ElasticSearch) using a Kubernetes Operator which is a way of managing change in a kubernetes cluster.
