Powershell - Retrieve values from Azure (az) commands-CodePudding

I'm trying to write a simple script to retrieve a key value from Azure Storage account. Below is the code:

az login
az account set --subscription 1111-222-3333-444-55555555


$azure_blob_login = "teststorage123"
$azure_blob_access_key = az storage account keys list --account-name $azure_blob_login


Write-Output $azure_blob_access_key
Write-Output $azure_blob_access_key[0]

The output from the first write-output is:

[
  {
    "creationTime": "2022-02-23T06:45:00.085500 00:00",
    "keyName": "key1",
    "permissions": "FULL",
    "value": "11111111111111111111111111111111111111111111111"
  },
  {
    "creationTime": "2022-02-23T06:45:00.085500 00:00",
    "keyName": "key2",
    "permissions": "FULL",
    "value": "22222222222222222222222222222222222222222222"
  }
]

However the output from the second write-output where I am trying to index to just get the first value in the array is just: [

Anyone know how I can return the value from this az command and only get the first "value" entry from the first entry in the array?

Thanks,

The default output from Az cli is JSON.

If you want to create an array of properties you would have to convert the az cli output to a psobject

$keys = $azure_blob_access_key | ConvertFrom-Json
$keys[0]
