I’ve been looking at K3s deployed on FCOS, but I have no clue how I’m supposed to use Terraform to deploy FCOS.
My understanding is that FCOS is supposed to be ephemeral and re-deployed every so often, which would imply the use of a hypervisor like Proxmox on the host, but Proxmox does not play well with Terraform.
I also considered OpenStack, but it’s way over my head. I have a very simple single-node Kubernetes setup to deploy using GitOps, and nothing seems to fit the bill.
Keep in mind that this post is by a company that offers one of the options they compare. So there is an obvious conflict of interest, and I wouldn’t trust the conclusions that were reached
And obviously their option is the “best”. From the conclusion:
Talos Linux is unique. It’s the only option that includes OS management in a purpose-built distribution for running Kubernetes. There’s no compromise for scaling up or down. In terms of small-scale numbers, it “wins” in several of the examined categories, including memory usage, disk r/w, and installation size. But all of these metrics are side effects of Talos Linux’s defining characteristic: It’s simple.
Playing with Talos Linux is one of the reasons I switched to NixOS on my main computer, I loved the concept
You could try mine, SimpleK8s (kubeadm, containerd, systemd, buildroot), ~50Mb single file (kernel+initramfs). https://simplek8s.org/
The current footprint is lower than every alternatives commented on this article.
