External Cloud Provider

To deploy a cluster using external cloud provider, create a cluster configuration with the external cloud provider template or refer to helm chart.

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
