Introduction

This repository provides the Azure implementation of the Kubernetes cloud provider interface.

This is the "external" or "out-of-tree" cloud provider for Azure. The "in-tree" cloud provider has been deprecated since v1.20 and only bug fixes are allowed in its Kubernetes repository directory.

Current status

cloud-provider-azure has been GA since v1.0.0. Releases are available from the Microsoft Container Registry (MCR).

The latest release of azure-cloud-controller-manager and azure-cloud-node-manager can be found at

  • mcr.microsoft.com/oss/kubernetes/azure-cloud-controller-manager:v1.27.7
  • mcr.microsoft.com/oss/kubernetes/azure-cloud-node-manager:v1.27.7

Run

To run azure-cloud-controller-manager locally:

azure-cloud-controller-manager \
    --cloud-provider=azure \
    --cluster-name=kubernetes \
    --controllers=*,-cloud-node \
    --cloud-config=/etc/kubernetes/cloud-config/azure.json \
    --kubeconfig=/etc/kubernetes/kubeconfig \
    --allocate-node-cidrs=true \
    --configure-cloud-routes=true \
    --cluster-cidr=10.240.0.0/16 \
    --route-reconciliation-period=10s \
    --leader-elect=true \
    --secure-port=10267 \
    --v=2

To run azure-cloud-node-manager locally:

azure-cloud-node-manager \
    --node-name=$(hostname) \
    --wait-routes=true

It is recommended to run azure-cloud-controller-manager as a Deployment with multiple replicas, or directly with kubelet as static Pods on each control plane Node. See here for an example.
