Azure File Copy Fails - azure

Question

I have this task in Devops: I want to copy a text file from blobstorage to a VM.
- task: AzureFileCopy#4
inputs:
sourcePath: 'https://storagename.blob.core.windows.net/container/file.txt'
azureSubscription: 'subscription connection'
storage: 'a_storage_in_subscription'
resourceGroup: $(rgName_of_VM)
destination: 'azureVMs'
MachineNames: $(ipofVM)
vmsAdminUserName: $(adminUsername)
vmsAdminPassword: $(adminPassword)
targetPath: 'c:\files'
But it fails with Upload to container: '8e107770-69d8-xxx' in storage account: 'a_storage_in_subscription' with blob prefix: '' failed with error: 'AzCopy.exe exited with non-zero exit code while uploading files to blob storage.' For more info please refer to https://aka.ms/azurefilecopyreadme
My understanding is that the task copies the file and first puts it in a container in the 'storage' field (a guid is used to create it). The task succeeded in it but then error happened. What am I doing wrong?

Answer 1

If you re-run this failed pipeline along with setting system.debug to true, you will see another message which can explain more detailed for why it failed: failed to perform copy command due to error: cannot start job due to error: cannot scan the path \\?\D:\a\1\s\https://storagename.blob.core.windows.net/container/file.txt.
Now, you should know that why you encountered that error message. That's because our Azure File Copy task does not support to use HTTPS url in sourcePath. The value of sourcePath must satisfied on below mentioned:
Since we does not support to use HTTPS url here. As a work around, you can firstly download this file into build working directory firstly by using Azure cli command. Then upload it to AzureVM:
- task: AzureCLI#1
displayName: 'Azure CLI '
inputs:
azureSubscription: {subscription}
scriptLocation: inlineScript
inlineScript: |
mkdir $(Build.SourcesDirectory)/File
az storage blob download --container-name {container name} --file $(Build.SourcesDirectory)/file --name {file name} --account-key $(accountkey) --account-name {blob name}
- task: AzureFileCopy#4
displayName: 'AzureVMs File Copy'
inputs:
SourcePath: '$(Build.SourcesDirectory)/File'
azureSubscription: {subscription}
Destination: AzureVMs
storage: {storage}
resourceGroup: '{resource group}'
vmsAdminUserName: {login name}
vmsAdminPassword: {login password}
TargetPath: 'xxx'
Note: You can get the accesskey from this tab:
Now, you can see that you can succeed to upload file to AzureVM.
