So it sounds as if you've sort of outgrown the command line but aren't sure you want to jump in on self-managed Kubernetes. You'd have to look at the costs but maybe some sort of managed offering would work for you. It could scale up for larger sites but would be fairly simple for smaller ones--especially with standardized configurations.

You could look at the big cloud providers directly. OpenShift [I work at Red Hat] also has a few different types of managed offerings.
