How can I deploy a k3s cluster on vSphere using Rancher and resolve a 'waiting for cluster agent to connect' error?

Answer

To resolve the 'waiting for cluster agent to connect' error when deploying a k3s cluster on vSphere using Rancher, you may need to deploy the vSphere cloud provider. The provider is bundled with RKE1 and RKE2 but not k3s. Check out the documentation on how to deploy Kubernetes on vSphere with Helm at https://github.com/kubernetes/cloud-provider-vsphere/blob/master/docs/book/tutorials/kubernetes-on-vsphere-with-helm.md for more information.

you probably need to deploy the vsphere cloud provider. One is bundled with RKE1 and RKE2 but not K3s.
