Develop a C# IoT Edge module to move files with Azure Stack Edge

Luis Molina Martinez 6

Hi all,

I´m trying to follow this tutorial https://learn.microsoft.com/en-us/azure/databox-online/azure-stack-edge-create-iot-edge-module#update-the-module-with-custom-code along this other https://learn.microsoft.com/en-us/azure/databox-online/azure-stack-edge-deploy-configure-compute-advanced, the code is working, I put a file in the local share and the trigger jumps, my module installed in the ASE recognizes the event, the issue comes when dealing with the routes, in the second article there is a configuration

{  
   "HostConfig":{  
      "Binds":[  
         "/home/hcsshares/mydbesmbedgelocalshare1:/home/input",  
         "/home/hcsshares/mydbesmbedgeshare1:/home/output"  
      ]  
   }  
}

I´m not able to fill it accordingly, moreover the properties of my local share doesn´t shows /home..., it is just the name of the share, so in my case I had to put this:

"settings":{  
      "image":"${MODULES.FileCopyModule}",  
      "createOptions":{  
         "HostConfig":{  
            "Binds":[  
               "/sharetdunfslocal:/home/input",  
               "/nfslocal2:/home/output"  
            ]  
         }  
      }  
   }

but when the trigger raises, I got an error saying that the file "/home/input/test.txt" doesn´t exist, any tip?

Regards.

Hello @Luis Molina Martinez ,Thanks for reaching out on this forum.

Below is the response from our product team, I hope this helps with your initial query.

There is a step-by-step doc that walks through this exact scenario: reading/writing to files on ASE. The article is here: Tutorial to filter, analyze data on Azure Stack Edge Pro FPGA with compute | Microsoft Learn

Hello @Luis Molina Martinez ,

The binding is bound to certain path rules like:

{
"HostConfig": {
"Binds": [
"/var/iot-edge-filewatcher/exchange:/app/exchange"
]
}
}

Take a look at this blog post.

There you see an example of a C# module accessing a local folder in Linux.

You can test your module with:

sudo docker exec -i -t echo /bin/bash

Hi @Sander van de Velde | MVP , thanks for the info, in your blog post the folder in the host is created with the deployment, but in my case I'm using an Azure Stack Edge device, there is no access to the shell,I want to use a Share created in the Azure Stack Edge. Anyway your post give me and idea on how to debug the issue, thanks.

Hi Dear @Sander van de Velde | MVP ,

sorry for the delay, I had another fire to fight and then I went on leave, at the end what works is to use Mounts instead of Binds, in one of the original posts there was some information about using the ASE PRO (not FGPA), but I didn't noticed it at the beginning.

I'm going to continue the testing, for now I noticed that the trigger is really slow, it takes too many time after uploading the files.

Thanks for your support.
