Kubernetes has a definite whiff of NoSQL - a massively hyped tool/technique originating from Google with oversold benefits. I tried it about 6 months back with the intent of using it in a corporate prod environment and getting set up was... a massive pain in the ass to say the least - compared to the existing ansible set up. It was supposed to solve headaches, not cause them. I wasn't impressed. I wouldn't be surprised if it ends up being "Angular 1.0" to someone else's react.

i set up a kubernetes cluster 1 year ago at work and a private one last weekend. last year took, i think 2 days. my private one was up and running within ~1h, including writing the ansible role to first install binaries/dependencies and join the cluster as a worker node. either you didn't use kubeadm to set it up or ... i have no idea how you could've possibly failed. its pretty much (all) ${packagemanager} install docker-ce kubectl kubelet kubeadm (master) kubeadm init -> prints token (node) kubeadm join ${token}

  Jeff Geerling even wrote an Ansible role to do all of the heavy lifting for you. I've used it alongside vagrant to spin up a three node cluster in ~15 minutes. https://github.com/geerlingguy/ansible-role-kubernetes https://github.com/geerlingguy/ansible-role-kubernetes

    I've used OpenStack a good bit, but not Kubernetes directly, and I have never set it up. Is there an up-to-date, in-depth tutorial around?

    He's written so many useful and maintained ansible roles.

  I didn't fail, I just couldn't see a strong ROI after doing a spike. I did use kubeadm. It required considerably more than just 3 simple steps required to get a basic working cluster up. Two days was more like it.

    Managing kubernetes yourself is a headache and why I more or less only consider managed services like Google Kubernetes Engine for real use-cases. That's why the original article showing that you could install and run it on a set of 3 micro preemptible instances for ~5 month was so compelling to me.

    how does kubeadm take two days. I had to rebuild my cluster recently and it literally took me 20 minutes.

      I didn't use it last time. It was marketed as beta iirc
