Once you configure the kubernetes network layer with whatever hosting platform you’re using, it’s really not difficult to administrate. It’s funny to me how much kubernetes hate there is on hn.
It’s not that hard to debug issues in kubernetes. Check status of pods, memory levels, storage mounts, network configurations, and the stacktrace you’re debugging. Not that difficult.
I’m not saying there aren’t edge cases, but if you set up your system with centralized logging (filebeat) and have some way to scrape metrics (jmx, built in tooling) you’ll be fine.
