Azure PowerShell docs style guide

This article focuses on Azure PowerShell conceptual and reference content available in the following GitHub repositories:

• azure-docs-powershell
• azure-powershell

Version

Unlike most Microsoft Learn documentation, the Azure PowerShell content in the azure-docs-powershell repository is maintained for multiple supported versions. For details on supported versions, see Azure PowerShell support lifecycle.

If an article references cmdlets from a preview module, that module must be explicitly installed unless the AzPreview module is already installed. This is because only generally available (GA) modules are included with the Az PowerShell module.

Viktigt

Don't use commands from the AzureRM PowerShell module in articles. AzureRM is deprecated.

Prerequisites

Always place Azure service prerequisites first, followed by Azure PowerShell and Azure Cloud Shell instructions. For example, "You must have Microsoft.Authorization/roleAssignments/write permissions to complete the instructions in this tutorial" should come first.

If all commands aren't compatible with Cloud Shell, instruct the user to install the Az PowerShell module locally. Include the following text in an H2 Prerequisites section.

markdown

- This tutorial requires that you run Azure PowerShell locally:
  - [Install the latest version of the Az PowerShell module](/powershell/azure/install-azure-powershell).
  - Connect to your Azure account using the
    [Connect-AzAccount](/powershell/module/az.accounts/connect-azaccount) cmdlet.

Formatting syntax elements in a paragraph

Follow the PowerShell-Docs style guide and Editor's checklist for formatting command syntax elements in Azure PowerShell documentation.

Don't link to cmdlet documentation when mentioning cmdlet names in a paragraph. Instead, surround the cmdlet name with backticks, which is styling for inline code (``). Add a references section towards the bottom of the page. List the cmdlet names in the references section and link to their associated reference article. For example:

markdown

This is an example of using the `Connect-AzAccount` and `Get-AzVM` cmdlets within a
paragraph.

## References

- [Connect-AzAccount](/powershell/module/az.accounts/connect-azaccount)
- [Get-AzVM](/powershell/module/az.compute/get-azvm)

Anteckning

Don't format text inside the brackets of a hyperlink. For more information about linking to Azure PowerShell content, see Linking to other documents.

Parameter order

Parameters for an Azure PowerShell cmdlet should appear in the order defined by the cmdlet help. A cmdlet can have multiple ways to provide the required parameters. When it does, follow the parameter set for the usage you're demonstrating. Connect-AzAccount is an example of a cmdlet with multiple ways to invoke it.

Variables

Avoid reusing variables across multiple code blocks.

The reader might complete the article steps in different sessions. Using variables across code blocks might cause errors if they're not set correctly. If you must use the variables across steps, make it clear that variables are reused in later steps.

Randomize passwords for new resources

If you're creating a resource that has a password associated with it, don't use a hardcoded password. Checking passwords into source control, even examples, is a security risk.

If the Azure resources in your article require a plain text password, use Read-Host to allow users to define their password. The MaskInput parameter prevents the password from being recorded in PowerShell's history.

PowerShell

$password = Read-Host 'Enter a Password' -MaskInput

Avoid naming conflicts

Some Azure resources, like Azure Container Registry and Key Vault, have resources tied to domain names. Those resources must have a globally unique name. For that reason, use a random value as part of names when uniqueness is required. If you don't, scripts fail to create required resources when multiple people run them. Randomness doesn't prevent conflict but can mitigate it.

Use Get-Random to add a random number to a name, for example:

PowerShell

$newAcrName = "myacr-$(Get-Random)"

Interactive code snippets

When to use interactive code snippets

If Cloud Shell supports every Azure PowerShell command in your article, tag your code blocks with azurepowershell-interactive to add the Open Cloud Shell button to the snippets:

```azurepowershell-interactive
Get-AzResourceGroup | Select-Object -Property ResourceGroupName, Location
```

When NOT to use interactive code snippets

Don't use azurepowershell-interactive if your article includes any Azure PowerShell commands that don't work in Cloud Shell. Use azurepowershell only. For example, the Install-AzAksCliTool cmdlet is unsupported in Cloud Shell:

Azure PowerShell

Install-AzAksCliTool

If you mix Cloud Shell functional commands with commands that don't work in Cloud Shell, you risk frustrating customers when only some commands work. Instead, stick with the azurepowershell language tag for all code blocks to help avoid confusion.

Because users are already authenticated when logging into Cloud Shell, don't use the azurepowershell-interactive tag for code blocks containing only Connect-AzAccount. Use the azurepowershell language tag instead.

Update AzureRM to the Az PowerShell module

See Migrate Azure PowerShell from AzureRM to Az for information on how to update commands that use the AzureRM PowerShell module to the Az PowerShell module.
