What Operating System are you using (both controller, and any agents involved in the problem)?

Jenkins is hosted in AKS
Windows based VM agents

Reproduction steps

  1. Create Azure File Share in storage account and upload some files
  2. Create a Virtual Machine with Windows 10
  3. Connect the File share in VM as a mounted drive (using storage account)
  4. Create an image out of the Virtual Machine
  5. Create dynamic slave from the above image using Azure VM Agents plugin
  6. Login to the VM check if the mapped drive is available with contents
  7. Create a Pipeline Job to dir the contents of mapped drive

Expected Results

The contents of the mapped network drive should be displayed.

Actual Results

File Not found - error message

Anything else?

How are you mounting the drive? Can you give a bit more details please. The steps above aren't enough given I'm not too familiar with that area

Dear @timja,
Sure, please find further details.

Azure File Shares can be connected to VMs as mapped network drive.
https://docs.microsoft.com/en-us/azure/storage/files/storage-how-to-use-files-windows#mount-the-azure-file-share
New-PSDrive -Name -PSProvider FileSystem -Root -Persist

The drive is created and accessible when we login to the VM. But it is not accessible (from Jenkins Pipeline) in the way how the slaves are connected to Jenkins. I was using SSH lunching method for connection of slaves to Jenkins.

When I manually create node (slave agent in Jenkins) and connect the VM via JNLP in command prompt, I am able to access the mapped drive from Jenkins Pipeline. (Note: I have the enable the use WebSocket) option in Jenkins slave agent configuration to establish the connection via JNLP)
image

But I am not able to use JNLP lunch option for agents created via Azure VM Agents plugin as it does not have a provision to enable usage of WebSocket.

I have enabled fixed port (5000) for JNLP connection, but this port is not reachable from Jenkins slaves.

Dear @timja,
I am able to connect the dynamic VM agents via JNLP (using websocket) with the following command in the initialization script:
$java -cp C:\agent.jar hudson.remoting.jnlp.Main -url "$jenkinsserverurl" -webSocket -workDir "C:\workspace" $secret "$vmname"

But still the mapped drive is not visible from the Jenkins Pipeline.
Any hints on how to access the file share from Jenkins VM agents would be greatly helpful.

Thanks,
Ram

is there a bat or powershell script you can run to mount the drive?

Yes, there is a powershell script to mount the drive. I tried doing it directly from Jenkins Pipeline job, the drive is getting created but it is not accessible.

Pipeline script:
// The following powershell script successfully creates a mount drive (T:) for the Azure file share (test-fs):
powershell '''
$pass="$env:storage_key"|ConvertTo-SecureString -AsPlainText -Force
$Cred = New-Object System.Management.Automation.PsCredential('localhost\labXXXst',$pass)
New-PSDrive -Name T -PSProvider FileSystem -Root "\\labXXXst.file.core.windows.net\test-fs" -Credential $cred -Persist
'''
// Linking happens successfully -> mapped drive and contents exists
bat 'mklink /d C:\tb_pub_point T:\tbpubpoint1\data'
// but they are not accessible via Jenkins
bat 'dir C:\tb_pub_point'

Output:
[Pipeline] powershell
