Azure Blob Storage is a service for storing large amounts of unstructured data, such as text or binary data. It is commonly used for serving documents, images, and other files directly to browsers. If you're working in a Windows environment and need to upload files to Azure Blob Storage, you can use the Set-AzStorageBlobContent cmdlet in PowerShell. This article will guide you through the process of using this cmdlet to upload files to Azure Blob Storage.

Prerequisites

Before you begin, ensure that you have the following:

1. Azure Subscription: You need an active Azure subscription.

2. Azure Storage Account: A storage account in Azure where you will upload your blobs.

3. Azure PowerShell Module: Ensure that you have the Azure PowerShell module installed. You can install it using the following command in PowerShell:

   Install-Module -Name Az -AllowClobber -Scope CurrentUser

4. Authentication: You need to authenticate to your Azure account. You can do this by running:

   Connect-AzAccount

Examples

Below are examples of how to use the Set-AzStorageBlobContent cmdlet to upload files to Azure Blob Storage.

Example 1: Upload a Single File

# Variables
$resourceGroupName = "myResourceGroup"
$storageAccountName = "mystorageaccount"
$containerName = "mycontainer"
$filePath = "C:\path\to\your\file.txt"

# Get the storage account context
$storageAccountContext = (Get-AzStorageAccount -ResourceGroupName $resourceGroupName -Name $storageAccountName).Context

# Upload the file
Set-AzStorageBlobContent -File $filePath -Container $containerName -Context $storageAccountContext

Example 2: Upload Multiple Files from a Directory

# Variables
$resourceGroupName = "myResourceGroup"
$storageAccountName = "mystorageaccount"
$containerName = "mycontainer"
$directoryPath = "C:\path\to\your\directory"

# Get the storage account context
$storageAccountContext = (Get-AzStorageAccount -ResourceGroupName $resourceGroupName -Name $storageAccountName).Context

# Upload all files in the directory
Get-ChildItem -Path $directoryPath | ForEach-Object {
    Set-AzStorageBlobContent -File $_.FullName -Container $containerName -Context $storageAccountContext
}

Explanation

• Set-AzStorageBlobContent: This cmdlet is used to upload a file to a blob in a specified container within your Azure Storage Account.
• Get-AzStorageAccount: Retrieves the specified storage account, which is needed to obtain the storage context.
• Get-ChildItem: Retrieves the files from the specified directory.

Considerations

• Ensure that the storage account and container names are correct and that you have the necessary permissions to upload files.
• The file path must be accessible from your local machine.
