Kind of very basic issues IMO. The only one that's hard is logging. We are using K8s on AWS and I haven't found a good solution for logging centralization. Personally I don't like the Kibana interface for that kind of stuff.
My criticism to Kibana is that it runs all the queries for a dashboard in parallel. It overloads the Elasticsearch machine(s) even when there are only few data. A small single ES server would be enough if the queries would be run sequentially. I wonder if Elastic is in the business of selling multicore 32 GB servers that sit idle most of the time.
I use kibana to monitor logs over 60 containers. Sure, the initial dashboard is a pain to setup, but once you get going going its very useful
