Yesterday I stumbled upon a provider of managed k3s.
If you did not hear about k3s: it is a tiny Kubernetes distribution created by Rancher, which does some peculiar design approaches for minimal size and runtime overhead:
This makes k3s the ideal choice for small-scale systems, e.g. Raspberry Pi or small VMs from cloud providers.
Now CIVO - which originally focussed on an PAAS platform - is offereing a beta on its upcoming Kubernetes service based on k3s:
They will give you 70 EUR per month while in beta, and the prices are very reasonable, on par with e.g. DigitalOcean.
