Migrate from microk8s to rke2 for more HA is great but rke2 required more resources

We apologize for the inconvenience. We are migrating our infrastructure from microk8s to RKE2 for greater stability.

As we expanded our infrastructure, microk8s began to malfunction. After rebooting each node, our microk8s no longer functioned properly. Therefore, we are taking this opportunity to migrate to a more stable, production-grade infrastructure than microk8s.
