Troubleshooting

This guide (based on Minikube but others should be similar) explains general info on how to debug issues if a cluster creation fails.

Get logs of Cluster API controller containers

kubectl --kubeconfig minikube.kubeconfig -n capo-system logs -l control-plane=capo-controller-manager

Similarly, the logs of the other controllers in the namespaces capi-system and cabpk-system can be retrieved.

Master failed to start with error: node xxxx not found

Sometimes the master machine is created but fails to startup, take Ubuntu as example, open /var/log/messages and if you see something like this:

Jul 10 00:07:58 openstack-master-5wgrw kubelet: E0710 00:07:58.444950 4340 kubelet.go:2248] node "openstack-master-5wgrw" not found
Jul 10 00:07:58 openstack-master-5wgrw kubelet: I0710 00:07:58.526091 4340 kubelet_node_status.go:72] Attempting to register node openstack-master-5wgrw
Jul 10 00:07:58 openstack-master-5wgrw kubelet: E0710 00:07:58.527398 4340 kubelet_node_status.go:94] Unable to register node "openstack-master-5wgrw" with API server: nodes "openstack-master-5wgrw" is forbidden: node "openstack-master-5wgrw.novalocal" is not allowed to modify node "openstack-master-5wgrw"

This might be caused by This issue, try the method proposed there.

providerClient authentication err

If you are using https, you must specify the CA certificate in your clouds.yaml file, and when you encounter issue like:

kubectl --kubeconfig minikube.kubeconfig logs -n capo-system logs -l control-plane=capo-controller-manager
...
E0814 04:32:52.688514       1 machine_controller.go:204] Failed to check if machine "openstack-master-hxk9r" exists: providerClient authentication err: Post https://xxxxxxxxxxxxxxx:5000/v3/auth/tokens: x509: certificate signed by unknown authority
...

you can also add verify: false into clouds.yaml file to solve the problem.

clouds:
  openstack:
    auth:
        ....
    region_name: "RegionOne"
    interface: "public"
    identity_api_version: 3
    cacert: /etc/certs/cacert
    verify: false
You can’t perform that action at this time.
