That's probably because they are practically most used for the underlying OS of a Kubernetes host (seeing as how it is difficult by definition to configure an immutable install).
If you really think about it, what's the difference between spinning up a VM with a preconfigured image and spinning up a VM with an _immutable_ preconfigured image?
- ilbeeper 2y agoThe difference is that one is immutable and the other is not. One can be rolled back to earlier version while retaining user data and the other doesn't offer that ability.
- SR2Z 2y agoSure, but the GKE autoscaler will happily erase and recreate machines whenever it wants. Divergences from the base image are inherently limited because of that.
- ilbeeper 2y agoDespite the name, that's not what immutable distros are for. GKE won't let yet restore previous generation of configured and component versioned base image.
