As I've been fiddling with some various clusters that I am trying to get going, I've run into some areas where my understanding of Kubernetes needs some sharpening. I understand nodes and pods, I have ideas about services and deployments, and I get the basics of NodePort and ClusterIP. I've spun up a container and even done a 2 replica version. But I'm a bit weaker on images and troubleshooting. I can deploy a template, but I should be able to tweak it, but not so far. There is a way (attach?) to talk to containers, but that never seems to work for me. I can fetch container logs and sometimes execute commands, but I can't grok k8s container launch issues, like CrashLoopBackoff and ImageFetch. I'm able to get specific containers to work, but haven't exactly figured out how to connect through from outside places. Things like ExternalIP, LoadBalancer and Ingress should help, but I'm not sure what to use or why. The big thing is that I'm now starting to get into spots where I can see where I need to figure out more. And its clear where I need better understanding. This hands-on stuff actually helps a lot.
