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.

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?

Be aware of this bug at scale ... its interesting

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
