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

This template deploys a Datastax 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
region	Region name where the corresponding Azure artifacts will be created
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)
dnsName	DNS subnet name for operations center public IP address
virtualNetworkName	Name of the Virtual Network that is created and that resources will be deployed in to
adminUsername	Admin user name for the Virtual Machines
adminPassword	Admin password for the Virtual Machine
opsCenterAdminPassword	Datastax Operations Center Admin User Password
clusterName	The name of the new cluster that is provisioned with the deployment

Topology

This template deploys a configurable number of cluster nodes of a configurable size. The cluster nodes are internal and only accessable on the internal virtual network. The Datastax operatinos manager is exposed on a public IP address that you can access through a browser on port :8888 as well as SSH on the standard port.

##Known Issues and Limitations

• The template does not currently configure SSL on Datastax Operations Center virtual machine
• The template uses username/password for provisioning cluster nodes in the cluster, and would ideally use an SSH key
• The template deploys cassandra data nodes configured to use ephemeral storage and attaches a data disk that can be used for data backups in the event of a cluster failure resulting in the loss of the data on the ephemeral disks.
