### Azure

* Set node external IP for azure node when disabling UseInstanceMetadata. ([#60959](https://github.com/kubernetes/kubernetes/pull/60959), [@feiskyer](https://github.com/feiskyer))

* Changed default azure file/dir mode to 0755. ([#56551](https://github.com/kubernetes/kubernetes/pull/56551), [@andyzhangx](https://github.com/andyzhangx))

> To create a transition tier for transitioning objects to a prefix `testprefix` in `azurebucket` on Azure blob using `mc`:

```
 mc admin tier add azure source AZURETIER --endpoint https://blob.core.windows.net --access-key AZURE_ACCOUNT_NAME --secret-key AZURE_ACCOUNT_KEY  --bucket azurebucket --prefix testprefix1/
```

- The cloud config for Azure cloud provider can now be initialized from Kubernetes secret azure-cloud-provider in kube-system namespace
    - the secret is a serialized version of `azure.json` file with key cloud-config. And the secret name is azure-cloud-provider.
