Is there a way to upgrade a cluster without changing the Pods CIDR, or to somehow reset it afterward?
My cluster only has one node, and it had the pod CIDR 10.244.0.0/24. I did an upgrade to change the Kubernetes version, and now it's 10.244.1.0/24. Is there a way to go back to 10.244.0.0/24?
It's important to me because I am using the subnet and the cluster IP as configurations for an external site 2 site VPN and I can't change the remote configurations anytime I need to perform an upgrade.
I read the instructions from here, but I couldn't find a way to solve it.
