How the rke2-coredns-autoscaler pod enters CrashLoopBackOff after a node restart and how to resolve it in Automation Suite.
Description
After node restart, rke2-coredns-rke2-coredns-autoscaler can go in CrashLoopBackOff. This does not have any impact on Automation Suite.
Solution
Delete the rke2-coredns-rke2-coredns-autoscaler pod that is in CrashLoopBackOff using the following command: kubectl delete pod <pod name> -n kube-system.
