There are definitely a lot of moving parts in Kubernetes just to get it running and it was a big hurdle to get everything set up (I'm running a vanilla cluster in Vagrant).

The documentation definitely covers a lot, but I found myself hunting issues down for trying to get something to work like getting k8s to schedule pods across a flannel overlay network and making sure traffic is being routed properly. Of course, you don't have to worry about any of this if you use GKE or another cloud provider.

Once I got that set up, everything worked beautifully. I can just write a config and apply it to the cluster and services are deployed and scaled and whatnot. Treating your cluster as a pool of resources is pretty powerful. There are a lot of Kubernetes API objects (Deployments, Stateful Sets, Daemon Sets, ConfigMaps, Secrets), but everything has a purpose and Kubernetes makes everything come together nicely.

The Kubernetes Slack channel was really helpful for me as well, there's a lot of nice and friendly people there willing to answer your questions and help you debug your setup.
