Scaleway Kapsule and Rancher-managed Hetzner Kubernetes clusters

I honestly think this is the 3rd time I’m moving things around. First I was on Proxmox managing myself a cluster of bare-metal Hetzner (from the server auction page). Then I was torn between a home server and one on Hetzner. I was using many images from the TurnKey Linux project. Nice, interesting but required immense investments of time.

Then I decided I wanted managed Kubernetes services. Not long ago (half-a-month) did I went over to Digital Ocean’s managed Kubernetes service. For not a small price, got a 3 node cluster with 24GB of RAM and 12 cores. Started installing my stuff and quickly ran out of resources only to be forced to pay more.

Swithing oceans, from Heztner to Digital Ocean

I think I’ve ignored the Kubernetes movement for many years now. I used to maintain Docker-based infrastructures a couple of years ago, over bare-metal, mostly for work purposes. It was an interesting learning experience back then in the details of the containers foundation.

Still, I am still prudent about infrastructure in general and for a long time have favored pure and simple bare-metal or bare-metal + VM solutions in favor of containers for most of the critical data workloads (a.k.a. Big Data). Even in work deployments, we bypassed the usual performance penalties of containers by bind mounting the disk or using IPVLAN for networking when pure performance was needed. My favoritism for bare-metal is based on the fact that you can’t just ignore +50 years of evolution and documentation (if we intent on saying that we consider the “birth” of 1st operating system (UNIX) in 1969). I don’t want to go earlier than that …
