Tortoise: Shell-Shockingly-Good Kubernetes Autoscaling

I'm pretty sure cluster-autoscaler evicts pods if he decides that this particular node could be removed. I saw that in my cluster and had to apply annotation to some pods to prevent that. So it does packing to some extent.

I'm using managed kubernetes, but from a relatively small provider and I doubt they did any custom coding for their autoscaler.

I agree that it could do more. Sometimes I have to manually juggle pods around to remove one node, if scheduler did bad job.

I'm pretty sure your provider uses some autoscaler from one of the projects.

It has to know how to schedule new nodes which is provider dependend.

But thats my critisism: I believe that the autoscaler should be a k8s core component and not a 'select whatever opensource project you like based on no evidence OR if you are lucky based on experience someone else made over the years with all the choices out there'.

But as you write it yourself: You still need to do something manually and i bet you don't have that much control over telling the autoscaler to act differently depending on the pods.
