One thing I've found about k8s is running a cluster can be very costly, and using a managed cluster on one of the big three clouds is even more so. Also, when rolling your own cluster it requires a lot of elbow grease to get things in a working state, and even more to keep things working. It feels awesome from a developer standpoint once you work out all the kinks. It's very natural describing your service with a bit…

That's the exact same feeling I get too. If I'm a mom/pop shop online, why can't I get a k8s cluster w/just 1 machine for $5/month? I mean the big three (4 w DO) can all get you a bare machine for $5/mo that can run Docker. Why not give the k8s management side for free for those people?

If you're mom/pop online shop and just need 1 machine you don't need k8s. KISS principle applies.

Because that's more the realm of:

https://www.digitalocean.com/products/kubernetes/

https://www.scaleway.com/en/kubernetes-kapsule/

IaaS model is more 'everything is chargeable in small units', a free control plane doesn't really gel with that IMO, and also they have some huge users that it'd cost a lot to run the control plane for, pushing up the price of what you connect to it (or something must give) and making more PaaS-style like DO & Scaleway anyway.

Well, in this case the pop is me, and I know k8s but I don't want to invest 15-35 / month on a side project but would still rather have a decently managed site rather. I don't want to go back to FTP crap at this point.

A car is a hugely complicated machine and I'm sure in the 1910s people said only some people will ever need them. Bad analogy considering cars kill lots of people but take that part out :)

You can get a small cluster from Digital Ocean pretty cheaply. It's more than $5 (I forget the exact price) but they'll provide a free master node and then you just pay for one additional kubelet (and you can add more as you need them). I have used it for one hobby project and have been pretty happy with it.

A ton of the value from k8s is in the programmatic and replicable configuration. 1 computer pets are still bad in a mom and pop shop. 1 computer livestock is still better.

Hi everyone! Article author here!

My friend and colleague, Paul Stack: https://twitter.com/stack72 are at very opposite ends of the spectrum when it comes to Kubernetes. We put our heads together and tried to create a balanced take on Kubernetes where our opinions didn't cloud the article. It's obviously very polarizing, but I think we managed to ask some good questions before you started the adoption process.

Would love to hear more via twitter too! https://twitter.com/briggsl

I kind of don't understand why people don't use managed K8's and avoid needing to pay ops people to manage their setup. One can learn the developer side of K8's in a week or so enough to be deploying apps and setting up services and pods without the overhead of managing etcd and distributed clusters.

I use managed k8s, but have sympathy for the bare metal folks. Wiring servers together using kubeadm is so simple and powerful that the missing pieces of the puzzle (networking and storage, for example) feel frustratingly close.

In an ideal world, you could purchase or rent commoditized resources (compute, storage, bandwidth) and have those resources deploy your application in a standardized way. K8s is so close to that out of the gate, that having to use cloud provider's expensive and proprietary offerings feels sub-optimal.

I agree that cloud offerings are the way to go for anyone without good reasons not to (eg compliance, lack of connectivity, or full control over upgrades). But a lot of the "I prefer on prem" attitude comes from realizing that having a black box of an ingress controller on my cluster isn't the end state of how apps get deployed

Haha.

I forgot to tear down a small EKS cluster last month. 4 days, 60€.

You can run a single-core preemptible instance on GKE for $7/month. As long as you keep the one instance alive that persists the cluster.
