Running on an Existing Kubernetes Cluster on Huawei Cloud

Prerequisites

  • Kubernetes cluster on Huawei Cloud, version range v1.20 ~ v1.23.

Update cluster configurations

  • Add --cloud-provider=external to kube-controller-manager and kube-apiserver config

kube-apiserver and kube-controller-manager MUST NOT specify the --cloud-provider flag (or specify --cloud-provider=external). This ensures that it does not run any cloud specific loops that would be run by cloud controller manager.

  • Add --cloud-provider=external to kubelet on each node

kubelet MUST run with --cloud-provider=external. This is to ensure that the kubelet is aware that it must be initialized by the cloud controller manager before it is scheduled any work.

Install Cloud Provider for Huawei Cloud

  • Create the cloud-config secret in Kubernetes cluster

Create the cloud-config file according to cloud-config in master node or control-plane, see Huawei Cloud Controller Manager Configurations for configurations description.

Use the following command create cloud-config secret:

kubectl create secret -n kube-system generic cloud-config --from-file=./cloud-config
  • Create RBAC resources
kubectl apply -f  https://raw.githubusercontent.com/kubernetes-sigs/cloud-provider-huaweicloud/master/manifests/rbac-huawei-cloud-controller-manager.yaml
  • Install the Huawei Cloud Provider Manager
kubectl apply -f  https://raw.githubusercontent.com/kubernetes-sigs/cloud-provider-huaweicloud/master/manifests/huawei-cloud-controller-manager.yaml
  • Check the running status
# kubectl get pod -n kube-system | grep huawei-cloud-controller-manager
huawei-cloud-controller-manager-5f4b7995fc-s6b7p   1/1     Running   0          2m36s

When the status of Pod huawei-cloud-controller-manager is running, the installation is successful.
