Bicep Framework for deploying CBS on Azure

The Bicep framework for CBS deployment comes with Bicep templates and bash scripts, combined from following modules:

• Module #01 (Prerequisites) - this module deploys all the resources required for CBS deployment, including Virtual Network, User-Managed Identity, Custom Role, and others.

• Module #02 (CBS Managed App) - this module deploys the CBS Managed App itself into the environment with all prerequisites met.

• Module #03 (Test VM) - This module provisions a test Virtual Machine (VM) of Windows Server 2019 with pre-installed MS SQL server and configures test volumes in CBS instance to mount them via iSCSI protocol.

• Module #04 (QuickStart Demo Deployment) 🧪 - For hands-on/testing purposes, this module combines all modules #01-#03 (described above) and deploys all required resources, CBS Managed App and a test Virtual Machine in the single deployment script.

Prerequisites

• bash
• Docker or Windows (WSL recommended) / Linux^[1] / MacOS^[2]
• az-cli, bicep-cli, jq (all should get installed with setup-machine script or included in the Dockerfile)

^[1],[2] these OS are not fully tested, please report any issue you find

Installation

You can also run all commands in this repo on your computer or in container using the prepared Dockerfile in the repo.

In Docker container

1. Build the container image with command:

   $ docker build . -t cbs-bicep

2. Run the container:

   $ docker run -v .:/data -it cbs-bicep

3. Follow instructions on screen to authenticate into Azure CLI via device code login method.

or:

On local computer

1. Add permissions to execute scripts:

   $ chmod +x 00-setup-machine.sh 01-deploy-prerequisities.sh 02-deploy-cbs.sh 03-deploy-test-vm.sh deploy-quickstart.sh

2. Run the 00-setup-machine.sh script to install all required tooling and log into Azure.

   ./00-setup-machine.sh

Usage

The repository contains 4 modules for deploying CBS on Azure using infrastructure-as-code Bicep templates.

These modules can be customized and modified, for example, to be incorporated into your landing zone templates.

Module #01 - CBS Prerequisites

The script 01-deploy-prerequisities.sh (Bicep template file prerequisities.bicep) deploys all required resources for CBS.

Deployed resources:

• vNET resource, including all required subnets
• public IP address + NAT gateway for system subnet
• user managed identity
• a custom role definition
• a role assignment

To use this module:

1. rename the file 01-prereq.bicepparam.example to 01-prereq.bicepparam

   $ mv 01-prereq.bicepparam.example 01-prereq.bicepparam

2. enter the necessary values into the 01-prereq.bicepparam file

3. execute the script

   ./01-deploy-prerequisities.sh

Module #02 - CBS Managed App

The script 02-deploy-cbs.sh (Bicep template file cbs-managed-app.bicep) deploys CBS managed application itself.

To use this module:

1. rename the file 02-cbs.bicepparam.example to 02-cbs.bicepparam

   $ mv 02-cbs.bicepparam.example 02-cbs.bicepparam

2. enter the necessary values into the 02-cbs.bicepparam file
   Remember that these Bicep modules are isolated from each other.
   If you want to run them one after the other, you'll need to pass some output values from the 01-deploy-prerequisities.sh script into the 02-cbs.bicepparam parameter file.

3. execute the script

   ./02-deploy-cbs.sh

Note

If you intend to use only a Bicep template for the programmatic deployment of CBS, you must also accept the Azure Marketplace license for the given product/plan. Since Azure does not support accepting licenses via Bicep templates, you must accept the license using PowerShell or Azure CLI before executing the Bicep deployment.

Module #03 - Test VM

The script 03-deploy-test-vm.sh deploys a test Windows Server VM with MS SQL server installed.

It automatically creates 3 volumes in the CBS array, and mount them on the VM via iSCSI to be used by SQL server.

To use this module:

1. rename the file 03-test-vm.bicepparam.example to 03-test-vm.bicepparam

   $ mv 03-test-vm.bicepparam.example 03-test-vm.bicepparam

2. enter the necessary values into the 03-test-vm.bicepparam file
   Remember that these Bicep modules are isolated from each other.
   If you want to run them one after the other, you'll need to pass some output values from the 02-deploy-cbs.sh script into the 03-test-vm.bicepparam parameter file.

3. execute the script

   ./03-deploy-test-vm.sh

Using the Test VM

The Test VM is configured to accept standard RDP connections from your public IP address.

In WSL, the deployment script should automatically open an RDP session to the VM.

If not, use a command:

$ mstsc.exe /v:<<public IP address>>

Inside the VM there is a shortcut on the Desktop called Open CBS Console for CBS management.

Default credentials:

User: pureuser
Password: pureuser

Please change these credentials immediately.

Module #04 - QuickStart DEMO Deployment

This repository contains a script deploy-quickstart.sh that combines all modules in the repository and enables easy testing and hands-on experience of the CBS (Pure Cloud Block Store) on Azure. With just one script, you can quickly set up and run a test environment to explore the features and capabilities of the CBS.

The script includes all required CBS resources and sets up a test Windows SQL Server VM with mounted CBS volumes via iSCSI.

To use this script:

1. rename the file quickstart-params.sh.example to quickstart-params.sh:

   $ mv quickstart-params.sh.example quickstart-params.sh

2. enter the necessary values into the quickstart-params.sh file
3. execute the script:

   $ ./deploy-quickstart.sh

Limitations / Troubleshooting

Common Deployment vNET

The prerequisites (Module #01) only supports a single virtual network scenario where all required subnets are deployed within one common vNET, as this is considered best practice. The use of multiple vNETs that are peered with each other is not supported by this framework.

However, the vNET does not have to be deployed within the same vNET. You can use the optional vnetRGName (for Module #02) parameter to specify the resource group for the vNET.

Test VM - SQL Extension Fails

"code":"Ext_StorageConfigurationSettings_ArgumentError",
"message":"Error: 'Failed to get all physical disks in the same storage pool.'"

The script used for deploying the test VM is intended for demonstration purposes only and is not of production quality. It does not have the ability to detect existing volumes in the CBS and fails on that.

For demonstration purposes, simply delete the volumes in the CBS and redeploy the test VM.
