-`clusterctl` contains a list of default providers. Right now, {{product}} is
-not part of that list. To make `clusterctl` aware of the new 
-providers, we need to add a clusterctl configuration file.

-mkdir -p ~/.config/cluster-api

+providers:
+  - name: ck8s

+    url: "https://github.com/canonical/cluster-api-k8s/releases/latest/bootstrap-components.yaml"
