How are you using vanilla Kubernetes? I've tried provisioning vanilla K8s on bare metal clusters and I found it to be pure PITA, even with Kubespray.

Rancher's RKE is the first installer I've come across that "just works". Run rke up against a cluster.yml and within minutes you have a HA cluster with ingress ready to rock. K3S is also looking quite good.

In contrast I've spent days staring down the abyss of vanilla K8s. If you have good alternatives for launching K8S on bare metal/on-prem clusters, would be game to try.

I stood up a vanilla baremetal cluster (on the latest Ubuntu) a few days back using Kubeadm ... it was fairly trivial to do. I used the NGINX Ingress and it was also generally straightforward (maybe took an hour or two to understand what was going on). Curious what we did different?

I saw Rancher's offering afterwards and it does look really slick .. the UI is bloody awesome. Wish I could get it for regular kubernetes.

Kubeadm is the "official" and certified tool, not Kubespray. It is easily scripted as well. If you're used to graphical installers though and don't like automation then by all means continue to use Rancher.
