This is an unsupported scenario, see rancher/rancher#14731 when there is an official solution.
When cattle-cluster-agent and/or cattle-node-agent are accidentally deleted, or when server-url/cacerts are changed.
c-xxxxx), its in the address bar when the cluster is selected
This is not official documentation/tooling, use with caution
This generate the Kubernetes definitions of the cattle-cluster-agent Deployment and cattle-node-agent DaemonSet, in case it's accidentally removed/server-url was changed/certficates were changed. It is supposed to run on every cluster Rancher manages. If you have custom clusters created in Rancher, see Kubeconfig for Custom clusters created in Rancher how to obtain the kubeconfig to directly talk to the Kubernetes API (as usually it doesn't work via Rancher anymore). For other clusters, use the tools provided by the provider to get the kubeconfig.
IMPORTANT: You get the cluster/node agents definitions from Rancher, and you apply them to the cluster that is created/managed so you need to switch kubeconfig to point to that cluster before applying them.
