How to run a Python function in Azure Function App to run a command in Azure (Windows) Virtual Machine cmd to copy a file stored in Azure blob storage?

Ruhul 1

I am trying to write a Python function in Azure Function App to run a command in Azure (Windows) Virtual Machine command prompt that will copy input.txt file stored in Azure blob storage into output.txt file in blob again. Is there anyone who can help me with this? What should be the steps to solve this problem?

I have managed to write into files in blob directly from my python function. But I need to copy the contents of input.txt into output.txt (both stored in Azure blob storage) by running a command in my Azure virtual machine. At least any link to useful resources would be appreciated.

Hi @RahulK,

Thanks for posting your query in Q&A forum.

Instead of running the commands in the VM, you can directly copy the contents of input.txt into output.txt from the python code and run this code in Azure python function. You can use the input and output blob bindings of Azure functions or use the blob python SDK in the python code and deploy to Azure python function. This might be a simpler approach.

If you would still like to run commands in VM from python functions, please let me know.

@MughundhanRaveendran-MSFT : Thank you for your reply. Actually, my organization already has some .exe apps which processes input.txt into output.txt, currently being used on-premises. However, we are going to transition to cloud soon. So, I need to move those .exe's to Azure cloud to perform the required operations. Initial plan is as I stated in the question above. Would appreciate any solution for this or any better idea. Thanks again. Looking forward.

@RahulK, If you have exisiting .exe apps, it can be run in the Azure webjobs. There is no need to complicate with Functions and python code.

Hi @MughundhanRaveendran-MSFT , The I'd be interested to know whether executing an .exe file on a windows VM or running a command on the Windows VM cmd is possible from my Python Function app in Azure. Is there any information you can share on this? We have a substantial dependency on software which exists on the VM, and we'll not be able to migrate into the cloud, so was looking for a means of kicking off a cmd command from the Azure function app itself. Thanks very much in advance
