Yeah, I feel you. I found kubernetes very hard to learn as well. I wanted was to find a good tool to run a SaaS (to handle 10k users). Only after reading up a lot did I even realize that this was not for me. I had fallen into the Hackernews hype trap and thought kubernetes is the right tool for me. I am back to my simple docker based deploys in 5 EC2 instances. It's very much by hand but works with some simple instru…

> I found kubernetes very hard to learn as well. This is why we went down the OpenShift root, but there are not shortage of people wrapping Kube in other things, which seems sensible for a lot of use cases.

I have deployed and I use OpenShift since more that one year but I think that Ansible Playbook is crappy. What is you feeling about that?

Those who have used kubernetes so far, what is your opinion on the kubernetes ecosystem? Is this the holy grail? Is there anything missing that you would like to have? I have found kubernetes hard to learn. There are a lot of concepts. That in itself isn't bad, but I have found that the quality of the documentation is variable.

I think it's the holy grail for stateless services. For stateful systems though, (that need to persist data) things can be tricky. Maybe the improved node affinity features in this release will improve things but I still feel limited because I can't seem to find a way to permanently bind a Pod to a specific host's file system. They keep pushing for NFS or other complex network file systems that add huge network I/O o…

FYI: Local Storage for stateful services will be tackled in the upcoming releases - https://github.com/kubernetes/community/pull/306

ACK. We recognize this aspect of the docs (engineers writing docs == encyclopedia articles). We have real, honest to goodness tech writers now, and they are working on it. One piece at a time.

I don't know if it's the holy grail but it's surely one of the nicest and most impressive piece of tech I've seen since I tried Asterisk 10 years ago and had a long OMG moment myself. The ecosystem is growing by the day and Kubernetes itself changes a lot very quickly. The pace of its development is sometimes crazy. You might find yourself trying to stay on top of the latest release just to notice there's a new one o…

> come back to Kubernetes once its release cycle is a bit saner for production environments

Out of curiosity, what sort of cadence would you like to see?

One feature release every six months.

Yes, it is the holy grail. Yes, the documentation is a bit spotty in some cases. We've been using kubernetes in GCE for about 1 year. We run both interactive services and batch jobs in 2 clusters: dev and production. The production cluster runs fully with declarative configs (we have a jenkins instance that performs the deployments of committed k8s configs). There are a couple of features that we are missing: (pod an…

Is your jenkins code public?
