# Cluster Autoscaler on Azure # Cluster Autoscaler on Azure
The cluster autoscaler on Azure scales worker nodes within any specified autoscaling group. It will run as a `Deployment` in your cluster. This README will go over some of the necessary steps required to get the cluster autoscaler up and running. The cluster autoscaler on Azure scales worker nodes within any specified autoscaling group. It will run as a Kubernetes deployment in your cluster. This README will go over some of the necessary steps required to get the cluster autoscaler up and running.
## Kubernetes Version ## Kubernetes Version
Cluster autoscaler must run on Kubernetes with Azure VMSS support ([kubernetes#43287](https://github.com/kubernetes/kubernetes/issues/43287)). It is planed in Kubernetes v1.10. Cluster autoscaler support two VM types with Azure cloud provider:
- vmss: For kubernetes cluster running on VMSS instances. Azure cloud provider's `vmType` parameter must be configured as 'vmss'. It requires Kubernetes with Azure VMSS support ([kubernetes#43287](https://github.com/kubernetes/kubernetes/issues/43287)), which is planed in Kubernetes v1.10.
- standard: For kubernetes cluster running on VMAS instances. Azure cloud provider's `vmType` parameter must be configured as 'standard'. It only supports Kubernetes cluster deployed via [acs-engine](https://github.com/Azure/acs-engine).
## Permissions ## Permissions

az ad sp create-for-rbac --role="Contributor" --scopes="/subscriptions/<subscription-id>" --output json az ad sp create-for-rbac --role="Contributor" --scopes="/subscriptions/<subscription-id>" --output json

And fill the values with the result you got into the configmap ## Deployment manifests
```yaml ### VMSS deployment
apiVersion: v1

TenantID: <tenand-id>
ScaleSetName: <scale-set-name>
kind: ConfigMap
metadata:

```
Create the configmap by running Pre-requirements:
- Get credentials from above `permissions` step.
- Get the scale set name which is used for nodes scaling.
- Encode each data with base64.
Fill the values of cluster-autoscaler-azure secret in [cluster-autoscaler-vmss.yaml](cluster-autoscaler-vmss.yaml), including
- ClientID: `<base64-encoded-client-id>`
- ClientSecret: `<base64-encoded-client-secret>`

- TenantID: `<base64-encoded-tenant-id>`

Note that all data should be encoded with base64.

### Standard deployment
Pre-requirements:
- Get credentials from above `permissions` step.
- Get the required paramters from acs-engine deployments (usually under directory `_output/<master-dns-prefix>` after running `acs-engine deploy` command)
- Get `APIServerPrivateKey`, `CAPrivateKey`, `ClientPrivateKey` and `KubeConfigPrivateKey` from `azuredeploy.parameters.json`
- If windows nodes are included, also get `WindowsAdminPassword` from acs-engine deployment manifests
- Get the initial Azure deployment name from azure portal. If you have multiple deployments (e.g. have run `acs-engine scale` command), make sure to get the first one
- Get a node pool name for nodes scaling from acs-engine deployment manifests
- Encode each data with base64.
Fill the values of cluster-autoscaler-azure secret in [cluster-autoscaler-standard.yaml](cluster-autoscaler-standard.yaml), including
- ClientID: `<base64-encoded-client-id>`
- ClientSecret: `<base64-encoded-client-secret>`
- ResourceGroup: `<base64-encoded-resource-group>`
- SubscriptionID: `<base64-encode-subscription-id>`
- TenantID: `<base64-encoded-tenant-id>`
- NodeGroup: `<base64-encoded-node-pool-name>`
- Deployment: `<base64-encoded-azure-initial-deploy-name>`
- APIServerPrivateKey: `<base64-encoded-apiserver-private-key>`
- CAPrivateKey: `<base64-encoded-ca-private-key>`
- ClientPrivateKey: `<base64-encoded-client-private-key>`
- KubeConfigPrivateKey: `<base64-encoded-kubeconfig-private-key>`
- WindowsAdminPassword: `<base64-encoded-windows-admin-password>`
Note that all data should be encoded with base64.
Then deploy cluster-autoscaler by running
```sh
kubectl create -f cluster-autoscaler-standard.yaml
```
To run a CA pod in master node - CA deployment should tolerate the master `taint` and `nodeSelector` should be used to schedule the pods in master node.
```sh
kubectl create -f cluster-autoscaler-standard-master.yaml
