I might be biased here, as I started as a side project and wanted to learn k8s in the process. It turned out quite funny to set up and I am happy with the result, except for the struggle I had to add SSL. I have 1 frontend, 4 micro-services and 2 postgres. One cluster for test, one for production.

I use Gitlab for CI, commits to master create a new docker image in the Gitlab registry. I manually trigger deployment on k8s with `kubectl rollout restart XXX`
