How to get container details from a storage account stored in an azure resource group

example.ps1

Import-Module AzureRM.Storage

$rgname="group"
$StorageAccountName="storage"
$container="container"

# getting Azure storage account key 
$fullkeys = Get-AzureRMStorageAccountKey -StorageAccountName $StorageAccountName  -ResourceGroupName $rgname

# the script will be using primary key
$key = $fullkeys[0].Value
## OLD (pre v1.4.0)
## $key = $fullkeys.Key1 # this differs to the Get-AzureStorageAccountKey cmdlet's output!

# getting storage account content 
$context = New-AzureStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $key 

# find my container
Get-AzureStorageContainer -Context $context -Name $container
