Autoscaler pod does not start because OOM

[manuelbuil]

Environmental Info:
RKE2 Version: master branch

Node(s) CPU architecture, OS, and Version:

Tested on Ubuntu 20 and opensuse Leap 15-SP3

Cluster Configuration:

1 server

Describe the bug:

The autoscaler crashes because of OOM. If I increase the memory to 20MB instead of 10MB, it works

Steps To Reproduce:

Deploy latest rke2 that has autoscaler enabled

Expected behavior:

I expect RKE2 to deploy correctly and have the autoscaler pod running

Actual behavior:

ausotcaler pod fails to run with OOM

Validated on a machine with 10MB of memory that rke2 installs and all system pods are up and running using master branch commit 80e3f842c31a4f65e3f4cf56e435bb7b751b8fe3
