How to publish custom machine configuration package artifacts

Before you begin, it's a good idea to read the overview page for machine configuration.

Machine configuration custom .zip packages must be stored in a location that's accessible via HTTPS by the managed machines. Examples include GitHub repositories, an Azure Repo, Azure storage, or a web server within your private datacenter.

Configuration packages that support Audit and AuditandSet are published the same way. There isn't a need to do anything special during publishing based on the package mode.

Publish a configuration package

The preferred location to store a configuration package is Azure Blob Storage. There are no special requirements for the storage account, but it's a good idea to host the file in a region near your machines. If you prefer to not make the package public, you can include a SAS token in the URL or implement a service endpoint for machines in a private network.

To publish your configuration package to Azure blob storage, you can follow these steps, which use the Az.Storage module.

If you don't have a storage account, use the following example to create one.

# Creates a new resource group, storage account, and container
$ResourceGroup = '<resource-group-name>'
$Location      = '<location-id>'
New-AzResourceGroup -Name $ResourceGroup -Location $Location

$newAccountParams = @{
    ResourceGroupname = $ResourceGroup
    Location          = $Location
    Name              = '<storage-account-name>'
    SkuName           = 'Standard_LRS'
}
$container = New-AzStorageAccount @newAccountParams |
    New-AzStorageContainer -Name machine-configuration -Permission Blob

Next, get the context of the storage account you want to store the package in. If you created the storage account in the earlier example, you can get the context from the storage container object saved in the $container variable:

$context = $container.Context

If you're using an existing storage container, you can use the container's connection string with the New-AzStorageContext cmdlet:

$connectionString = @(
    'DefaultEndPointsProtocol=https'
    'AccountName=<storage-account-name>'
    'AccountKey=<storage-key-for-the-account>' # ends with '=='
) -join ';'
$context = New-AzStorageContext -ConnectionString $connectionString

Next, add the configuration package to the storage account. This example uploads the zip file ./MyConfig.zip to the blob container machine-configuration.

$setParams = @{
    Container = 'machine-configuration'
    File      = './MyConfig.zip'
    Context   = $context
}
$blob = Set-AzStorageBlobContent @setParams
$contentUri = $blob.ICloudBlob.Uri.AbsoluteUri

Note

If you're running these examples in Cloudshell but created your zip file locally, you can upload the file to Cloudshell.

While this next step is optional, you should add a shared access signature (SAS) token in the URL to ensure secure access to the package. The below example generates a blob SAS token with read access and returns the full blob URI with the shared access signature token. In this example, the token has a time limit of three years.

$startTime = Get-Date
$endTime   = $startTime.AddYears(3)

$tokenParams = @{
    StartTime  = $startTime
    ExpiryTime = $endTime
    Container  = 'machine-configuration'
    Blob       = 'MyConfig.zip'
    Permission = 'r'
    Context    = $context
    FullUri    = $true
}
$contentUri = New-AzStorageBlobSASToken @tokenParams

Important

After you create the SAS token, note the returned URI. You can't retrieve the token after you create it. You can only create new tokens. For more information about SAS tokens, see Grant limited access to Azure Storage resources using shared access signatures (SAS).
