Claranet Azure pre-configuration script

The purpose of this script is to execute all necessary high privileges actions needed by Claranet for Azure subscriptions management.

This includes:

• Creation of a "claranet-tools" (or any other given name) service principal
• Creation of a "claranet-deploy" (or any other given name) service principal
• Rights assignment of Reader service principal on selected Subscription(s) with following rights:
  • Reader for inventory and monitoring purposes
  • Cost Management Reader for FinOps purposes
  • Log Analytics Reader for monitoring purpose
• Specific right assignment at the tenant level to read Reservations for FinOps purposes
  • Reservation Reader
• Rights assignment of Deployment service principal on selected Subscription(s) with following rights:
  • Contributor for Claranet deployment tools
  • User Access Administrator for Claranet deployment tools
• Optional creation of a "Claranet DevOps" user group and rights assignment on subscriptions

A report is generated at the end of the script and needs to be provided to Claranet in a secure way.

Prerequisites

In order to play this script, you'll need:

• Azure Active Directory privileges for creating Service Principals
• A terminal with the Azure CLI configured (it can be Azure Cloud Shell)
• Azure Subscriptions to configure rights on them

Important notes

If the given service principal name already exists, the script will re-use the existing one.

How to use it

With Azure Cloud Shell (recommended)

You can find Azure Cloud Shell documentation here: https://docs.microsoft.com/en-us/azure/cloud-shell/overview

Open Azure Cloud Shell from the Azure portal in Bash mode and launch the following command:

bash <(curl -s https://raw.githubusercontent.com/claranet/claranet-azure-pre-configuration/master/setup.sh)

From your terminal

Either clone this repository or download the script setup.sh locally and launch it in your terminal or launch the following command locally:

bash <(curl -s https://raw.githubusercontent.com/claranet/claranet-azure-pre-configuration/master/setup.sh)

Troubleshooting

I can't see my subscription in the list

If the subscription has been recently created, be sure to you've logged in with the Azure CLI after the subscription creation. This issue should not occur when using the Azure Cloud Shell method.

You can do this with the following command:

az login
