PowerShell Script be like,
- #join with azure account
- Join-AzAccount
- #get location
- Get-AzLocation | choose Location
- $location = “eastus”
- #create useful resource group
- $resourceGroup = “myResourceGroup”
- New-AzResourceGroup -Identify $resourceGroup -Location $location
- #create storage account
- $storageAccount = New-AzStorageAccount -ResourceGroupName $resourceGroup `
- -Identify “mystorageaccount” `
- -SkuName Standard_LRS `
- -Location $location `
- $ctx = $storageAccount.Context
- #create container
- $containerName = “quickstartblobs”
- New-AzStorageContainer -Identify $containerName -Context $ctx -Permission blob
- # add a file to the default account (inferred) entry tier
- Set-AzStorageBlobContent -File “D:_TestImagesImage000.jpg” `
- -Container $containerName `
- -Blob “Picture001.jpg” `
- -Context $ctx
- # add a file to the Sizzling entry tier
- Set-AzStorageBlobContent -File “D:_TestImagesImage001.jpg” `
- -Container $containerName `
- -Blob “Picture001.jpg” `
- -Context $ctx
- -StandardBlobTier Sizzling
- # add one other file to the Cool entry tier
- Set-AzStorageBlobContent -File “D:_TestImagesImage002.png” `
- -Container $containerName `
- -Blob “Picture002.png” `
- -Context $ctx
- -StandardBlobTier Cool
- # add a file to a folder to the Archive entry tier
- Set-AzStorageBlobContent -File “D:_TestImagesfoldernameImage003.jpg” `
- -Container $containerName `
- -Blob “Foldername/Picture003.jpg” `
