Kubernetes is dead simple to use, but can be a little daunting to set up.

Thankfully, that is changing with things like minikube, kubeadm, kops, and self hosted Kube.

I think the orchestration wars are essentially over. Kube has insane momentum, and is a well architected solution.

They're not over. Kubernetes might be dominant in the short term, but it's very complex compared to the use cases a lot of people have been using things like fleet for, and I for one will continue evaluating other options for that reason as most cluster deployments I work on by far have needs where the complexity of something like Kubernetes is totally unnecessary - there will be plenty of space for alternatives for that reason.

It looks like k8s is simplifying fast enough that it may eclipse the others. kubeadm is already a huge improvement.

kubeadm is not fixing the underlying complexity - it's putting a veneer on top. It's certainly helpful to simplify the deployment, but kubeadm is only needed in the first place because of how complicatd kubernetes is.

To be clear I'm not saying there aren't deployments where the complexity of something like kubernetes isn't necessary.

But most people only run a small number of servers. I'd argue most clusters people are deploying are going to stay below 10 servers for their entire lifetime, and a dozen or two services that generally tends to need basic high availability and load balancing and 1-3 different data stores with replication/data persistence requirements. For that kind of setup, while you certainly can run kubernetes, the complexity of it simply isn't needed.

That's the boat I'm I'm - we have less than a dozen services and all we need is packing them neatly on worker nodes and some load balancing. Setting up Kubernetes for that looked like an absolute overkill. I need to try Docker Swarm and Nomad again but either of them has to support rolling deploys out of the box - lasy time o checked neither of them did
