External Cloud Provider

All cluster templates are meant to be used with the external cloud provider for OpenStack. Refer to the external cloud provider repository or the helm chart for more details.

Steps of using external cloud provider template

• After control plane is up and running, retrieve the workload cluster Kubeconfig:

  clusterctl get kubeconfig ${CLUSTER_NAME} --namespace default > ./${CLUSTER_NAME}.kubeconfig
  

• Deploy a CNI solution (using Calico now)

  Note: choose desired version by replace <v3.23> below

  kubectl --kubeconfig=./${CLUSTER_NAME}.kubeconfig apply -f https://docs.projectcalico.org/archive/v3.23/manifests/calico.yaml
  

• Create a secret containing the cloud configuration

  templates/create_cloud_conf.sh <path/to/clouds.yaml> <cloud> > /tmp/cloud.conf
  

  kubectl --kubeconfig=./${CLUSTER_NAME}.kubeconfig create secret -n kube-system generic cloud-config --from-file=/tmp/cloud.conf
  

  rm /tmp/cloud.conf
  

• Create RBAC resources and openstack-cloud-controller-manager deamonset

  kubectl --kubeconfig=./${CLUSTER_NAME}.kubeconfig apply -f https://raw.githubusercontent.com/kubernetes/cloud-provider-openstack/master/manifests/controller-manager/cloud-controller-manager-roles.yaml
  kubectl --kubeconfig=./${CLUSTER_NAME}.kubeconfig apply -f https://raw.githubusercontent.com/kubernetes/cloud-provider-openstack/master/manifests/controller-manager/cloud-controller-manager-role-bindings.yaml
  kubectl --kubeconfig=./${CLUSTER_NAME}.kubeconfig apply -f https://raw.githubusercontent.com/kubernetes/cloud-provider-openstack/master/manifests/controller-manager/openstack-cloud-controller-manager-ds.yaml
  

• Waiting for all the pods in kube-system namespace up and running

  $ kubectl --kubeconfig=./${CLUSTER_NAME}.kubeconfig get pod -n kube-system
