Configuring Azure for Scuba clusters

This document shows you install the Azure NPM module, then use an Azure Subscription to configure an Azure instance for a Scuba cluster. Perform the tasks in the order listed. Click a link to jump to a topic.

Prerequisites must be satisfied before you begin the following tasks.

  1. Request core and storage quota from Azure

  2. Download and install the Azure NPM

  3. Log in to the Azure Subscription and configure ARM

  4. Create an application and a service principle

  5. Create a role and show the account

  6. Submit information to provision a Scuba cluster


To successfully complete this process, you must have the following:

1. Request core and storage quota from Azure

Request a core and storage quota for your cluster from Azure in advance. These quotas should match the requirements for your cluster layout, including some additional for buffer. Make note of this information, as you will need it for step 6, to provision the Scuba cluster.

For information on requesting core and storage quotas, see the Azure solutions documentation, or contact Azure Support.

2. Install the Azure CLI 

After completing step 1, you will need to install the CLI module for Azure using command line instructions with a tool such as Terminal. For more details, see Install the Azure CLI on Linux.

To download and install the Azure CLI, do the following:
  1. On your Ubuntu system, open a Terminal window and use the following command. For Mac and Windows systems, follow the instructions found here: How to install the Azure CLI.

$  curl -sL | sudo bash

3. Log in to Azure and (optionally) set your subscription

After installing the Azure CLI, log into your Azure subscription to complete the remaining steps.

To log in to Azure, do the following:
  1. In the Terminal window, use the following command to initiate logging into your Azure subscription.

$  az login

2. Use a web browser to open the page

3. Enter the displayed code to authenticate. In the following example, the subscription code is hidden.

To sign in, use a web browser to open the page and enter the code ######### to authenticate.
OPTIONAL: If your account manages multiple Azure subscriptions, do the following:

4. After you have logged in, list all Azure subscriptions you have access to. Make a note of the SubscriptionId for the subscription you will be using to set up Scuba.

$  az account list

5. With the SubscriptionId from above, use the following command to set which subscription you will be using for the remainder of this guide.

$  az account set -s <SubscriptionId>

4. Create an application and service principle

Next, you will create an application for Scuba with a client secret (password), and then use the AppID to create a service principle.

To create an application and a service principle, do the following:
  1. To create an application (for Scuba), use the following command. Make a note of the password you input, and the AppID ("id") that is displayed, for use in the next step.

$  az ad app create --display-name "Scuba" --password "<replace_with_random_password>"

2. Create a Service Principle using the AppId from the previous step. Make a note of the ObjectId that is displayed, for when you create a role in the next section.

$  az ad sp create --id <AppId>

5. Create a role and show the account

Finally, you will create a role using the ObjectId generated in the previous section, then show the account information.

To create a role and show the account, do the following:

1. To create a role, enter the following command using the ObjectId generated when you created a Service Principle in the previous section.

$  az role assignment create --role "Owner" --assignee-object-id <ObjectId> --scope /subscriptions/<SubscriptionId>

2. To show the details of your Azure account, enter the following command. Make a note of the TenantId in the output.

$  az account show

6. Submit information to provision a Scuba cluster

Now that you have set up and configured your Azure subscription, you have all of the information you need submit to Scuba to provision a new cluster in Azure. 

Submit the following information to Scuba for your cluster:
  1. The App Id that you generated when you created an application (in step 4).

  2. The Secret that you specified when you created an application (in step 4).

  3. The Tenant Id that you generated when showing the account (in step 5).

  4. The Region in which the cluster is to be deployed.

  5. The Subscription Id, from your Azure Portal.

  6. Cluster sizing defined with your Scuba implementation team, while Planning your Scuba deployment.

  7. Core and Storage quota you requested from Azure, such as:

    1. Quantity of VM Types with respective region:
      [Example: 500 cores,  D3s, East US 2]
      [Example: 100 cores, A7s, Central US]

Also include the following information:

  • Date of core fulfillment:

  • Request is temporary (Yes/No)? If yes, include the details.

  • Bursting usage pattern (Yes/No)? If yes, include the details.

  • Amount of Premium Storage in GB or TB: 

What's Next

The Scuba team will deploy and configure your new cluster once we have the above information. After the cluster is deployed, you are ready to add data.
