# Install a Datastax cluster on Ubuntu Virtual Machines using Custom Script Linux Extension

<a href="https://azuredeploy.net/" target="_blank">
<img src="http://azuredeploy.net/deploybutton.png"/>
</a>

This template deploys a Couchbase cluster on the Ubuntu virtual machines. This template also provisions a storage account, virtual network, availability sets, public IP addresses and network interfaces required by the installation.

The example expects the following parameters:

| Name | Description |
|:--- |:---|
| adminUsername | Admin user name for the Virtual Machines |
| adminPassword | Admin password for the Virtual Machines |
| storageAccountPrefix | Unique DNS Name for the Storage Account where the Virtual Machine's disks will be placed (multiple storage accounts are created with this template using this value as a prefix for the storage account name) |
| region | Region name where the corresponding Azure artifacts will be created |
| virtualNetworkName | Name of the Virtual Network that is created and that resources will be deployed in to |
| clusterName | The name of the new cluster that is provisioned with the deployment |
| tshirtSize | Higher level definition of a cluster size. It can take Small, Medium and Large values. This value causes cluster sizes with following characteristics. Small: 3xStandard_A2, Medium: 4xStandard_A6, Large: 5xStandard_D14 |
| vmNamePrefix | The prefix for the names of the VMs that will be provisioned |
| cbPackageDownloadBase | The URL base the Couchbase package is downloaded from |
| cbPackage | The Couchbase package name |
| jumpbox | Deploys two VMs, one Ubuntu, one Windows to access the cluster from the Internet |

Topology
--------

This template deploys a configurable number of cluster nodes of a configurable size. The cluster nodes are internal and only accessible on the internal virtual network. The cluster can be accessed either through a Ubuntu VM accessible through SSH (port 22), or a Windows VM through RDP, each having a separate public IP.

##Known Issues and Limitations
- The deployment scripts are not currently idempotent and this template should only be used for provisioning a new cluster at the moment.
