Find resource groups that contain tags on Azure using az cli

Sometimes you may need to massively search for resource groups or resources on Azure that have tags set. For example you may have some tags like temp resource that you want to delete with cron jobs. I myself wanted such a script and the first thing to do was to ask chatGPT about this. Although the provided answer is a good starting point I wanted a version that will bring all the resources that have a tag, and not a specific tag. I was searching for tags in general and not for a specific tag.

For such case I created my own script using az cli. In order to use it you will need to first login inside azure with your credentials.

az login

and then set your subscription

az account set --subscription "ID"

The script which brings resource-groups with tags can be found below.

$rgroups = az group list | ConvertFrom-Json
Write-Host Total Resource groups: $rgroups.Count  

$tags = @()
foreach ($item in $rgroups)
 if ( -not [string]::IsNullOrEmpty($item.tags)  ) { $tags+= $item } 
Write-Host Resource groups with Tags: $tags.Count  

echo $tags

When you run the script you can get the total number of resource groups and the ones that contain tags. You can then use the tags object to loop through the items with tags.

You can use the same logic to find also resources with tags inside an azure subscription

$resources = az resource list | ConvertFrom-Json
Write-Host Total Resources: $resources.Count  

$tags = @()
foreach ($item in $resources)
 if ( -not [string]::IsNullOrEmpty($item.tags)  ) { $tags+= $item } 
Write-Host Resources with Tags: $tags.Count  

echo $tags

Azure batch run task with container image through az cli and json rest api

Azure Batch can be a great tool for instant batch processing as it creates and manages a pool of compute nodes (virtual machines), installs the applications you want to run, and schedules jobs to run on the nodes. The important thing using this service is that there is no additional charge for using Batch. You only pay for the underlying resources consumed, such as the virtual machines, storage, and networking.

Azure Batch documentation – Azure Batch | Microsoft Learn

In this post I will demonstrate how one can create a new job and task from az cli for batch service. The trick in this implementation will be the json that is provided as input for the task definition as not all available options are provided from az cli.

The available az cli options are shown below.

One important missing configuration will be the container image that can be provided in the task trough Azure portal but not with az cli.

In order to create a task using az cli and bypass this issue, you can use the json-file parameter. This option will trigger the creation using the rest api and provide the parameters for the container image.

When there is a batch service pool available, you will need to create a job.

az batch account login -g RESOURCE_GROUP -n NAME
az batch job create --id JOB_NAME --pool-id POOL_NAME

Then you can create a new task using a json file.

az batch task create --job-id JOB_NAME --json-file

Task – Add – REST API (Azure Batch Service) | Microsoft Learn

The JSON file can be created as shown below.

  "id": "azcli-task",
  "displayName": "azcli-task",
  "commandLine": "azcli-task",
  "containerSettings": {
    "containerRunOptions": "--rm --workdir /app",
    "imageName": ""

When you execute the command you will get an output from the rest API for the created task.

output omitted

Finally you can find the new created task on Azure portal.

##[error]Script failed with error: Error: Unable to locate executable file: ‘pwsh’.

In AzureCLI@2 you may choose from a variety of options when it comes on how this task will be executed on the agent machine. I usually choose powershell for windows machines and powershell core for Unix based machines (pwsh).

Recently I got an error on a Windows machine when using Powershell core. The latest version of powershell which is currently on 7.* version can be used as pscore in the AzureCLI@2 task.

      - task: AzureCLI@2
        displayName: az cli task
          azureSubscription: 'SERVICE-CONNECTION'
          scriptType: 'pscore'
          scriptLocation: 'inlineScript'
          inlineScript: |

Error message:

##[error]Script failed with error: Error: Unable to locate executable file: ‘pwsh’. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also verify the file has a valid extension for an executable file.


In order to bypass this problem you should make sure that the latest version of powershell which is multiplatform should be installed on your system. At the time of this article this version is 7.*

After installing powershell you should make a restart also on the machine in order for the environmental variables to be added on PATH. Then you can execute your pwsh tasks on your agent machines.

Install azure cli using Powershell – silent mode

Az cli is a very important tool that one devops engineer may need to install on systems. You can perform a silent install on a windows machine using the powershell below:

$msiFilePath = "azure-cli.msi"
Invoke-WebRequest -OutFile $msiFilePath
$MSIArguments = @(
    ('"{0}"' -f $msiFilePath)
Start-Process "msiexec.exe" -ArgumentList $MSIArguments -Wait -NoNewWindow
Remove-Item -Path $msiFilePath  -Force

By running the powershell the download procedure will begin.

When the installation finishes you can locate it under installed programs:
