Execute powershell command without username password on Azure virtual machine

You can use az cli task on Azure devops in order to execute a powershell command inside a virtual machine without having to connect on it with username and password. In order to do that you have to use AzureCLI task and invoke a RunPowerShellScript. 

    - task: AzureCLI@2
      displayName: execute command inside vm
      inputs:
        azureSubscription: 'subscription'
        scriptType: 'ps'
        scriptLocation: 'inlineScript'
        inlineScript: 'az vm run-command invoke --command-id RunPowerShellScript --name $(vm_name) -g $(vnet_rg_name) --scripts "hostname"'

You should use your own variables regarding the vm_name and rg_name. This task will execute on a windows-latest machine and will output the hostname of the machine that is given as input with the variables.

Enable debug logs on Azure DevOps pipelines

In some cases you may need to troubleshoot your azure devops tasks inside a job and get a more detailed output than the default. You can enable a detailed log output using predefined variables. In more detail you can use System.Debug and set it to true.

variables:
  - name: System.Debug
    value: true

By doing so you will get more debug messages as shown in the below screenshot.

remote: TF401019: The Git repository with name or identifier does not exist or you do not have permissions for the operation you are attempting.

Recently from a new devops project I tried to checkout an external repository from another devops project and I got a failure. In more detail I was working on a new pipeline on devops project B and I was trying to fetch a repository from azure devops project A.

remote: TF401019: The Git repository with name or identifier does not exist or you do not have permissions for the operation you are attempting.

Searching it further I realized that the error was the job scope. In order to resolve I disabled the job scope for the current project (the one from which I run the pipeline – project B).

After disabling “Limit job authorization scope to current project for non release pipelines” then I was able to get a successful checkout for the external repository.

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 https://aka.ms/installazurecliwindows -OutFile $msiFilePath
             
$MSIArguments = @(
    "/i"
    ('"{0}"' -f $msiFilePath)
    "/qn"
    "/norestart"
)               
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:
