# Azure
|
|
|
|
> **Removed**: Since v1.31 (the Kubespray counterpart is v2.27), Kubernetes no longer supports `cloud_provider`. (except external cloud provider)
|
|
|
|
To deploy Kubernetes on [Azure](https://azure.microsoft.com) uncomment the `cloud_provider` option in `group_vars/all/all.yml` and set it to `'azure'`.
|
|
|
|
All your instances are required to run in a resource group and a routing table has to be attached to the subnet your instances are in.
|
|
|
|
Not all features are supported yet though, for a list of the current status have a look [here](https://github.com/Azure/AKS)
|
|
|
|
## Parameters
|
|
|
|
Before creating the instances you must first set the `azure_` variables in the `group_vars/all/all.yml` file.
|
|
|
|
All values can be retrieved using the Azure CLI tool which can be downloaded here: <https://docs.microsoft.com/en-gb/cli/azure/install-azure-cli>
|
|
After installation you have to run `az login` to get access to your account.
|
|
|
|
### azure_cloud
|
|
|
|
Azure Stack has different API endpoints, depending on the Azure Stack deployment. These need to be provided to the Azure SDK.
|
|
Possible values are: `AzureChinaCloud`, `AzureGermanCloud`, `AzurePublicCloud` and `AzureUSGovernmentCloud`.
|
|
The full list of existing settings for the AzureChinaCloud, AzureGermanCloud, AzurePublicCloud and AzureUSGovernmentCloud
|
|
is available in the source code [here](https://github.com/kubernetes-sigs/cloud-provider-azure/blob/master/docs/cloud-provider-config.md)
|
|
|
|
### azure\_tenant\_id + azure\_subscription\_id
|

`azure_subscription_id` -> ID field
|
|
|
|
### azure\_location
|

|
|
|
The name of the resource group your instances are in, can be retrieved via `az group list`
|

|
|
|
|
### azure\_security\_group\_name

|
|
|

### azure\_aad\_client\_id + azure\_aad\_client\_secret
|
|
|
|
These will have to be generated first:
|
|
|
|
- Create an Azure AD Application with:
|
|
|
|
```ShellSession
|
|
az ad app create --display-name kubernetes --identifier-uris http://kubernetes --homepage http://example.com --password CLIENT_SECRET
|
|
```
|
|
|
|
display name, identifier-uri, homepage and the password can be chosen
|
|
Note the AppId in the output.
|
|
|
|
- Create Service principal for the application with:
|
|
|
|
```ShellSession
|
|
az ad sp create --id AppId
|
|
```
|
|
|
|
This is the AppId from the last command
|
|
|
|
- Create the role assignment with:
|
|
|
|
```ShellSession
|
|
az role assignment create --role "Owner" --assignee http://kubernetes --subscription SUBSCRIPTION_ID
|
|
```
|
|
|
|
azure\_aad\_client\_id must be set to the AppId, azure\_aad\_client\_secret is your chosen secret.
|
|
|
|
### azure\_loadbalancer\_sku

|
|
|
|
### azure\_disable\_outbound\_snat

### azure\_primary\_availability\_set\_name
|
|
|
|
(Optional) The name of the availability set that should be used as the load balancer backend .If this is set, the Azure
|
|
cloudprovider will only add nodes from that availability set to the load balancer backend pool. If this is not set, and
|
|
multiple agent pools (availability sets) are used, then the cloudprovider will try to add all nodes to a single backend
|
|
pool which is forbidden. In other words, if you use multiple agent pools (availability sets), you MUST set this field.
|
|
|
|
### azure\_use\_instance\_metadata
|
|
|
|
Use instance metadata service where possible
|
|

## Provisioning Azure with Resource Group Templates
|
|
|
|
You'll find Resource Group Templates and scripts to provision the required infrastructure to Azure in [*contrib/azurerm*](../contrib/azurerm/README.md)
