Azure Functions Mounting Azure Storage File Shares

Description:

Follow this post to mount storage to your Function Apps. Following this post what I did was:

To Resolve:

1. Inside Azure Portal, open up Bash and type in:

   az webapp config storage-account add -g my_RG -n my-cool-function-app \
   --custom-id my-cool-function-app \
   --storage-type AzureFiles \
   --account-name my-cool-storage-account \
   --share-name my-share-name-in-storage-account \
   --access-key 1soD6tfrxdLD/8MMEzANYEgA== \
   --mount-path /data
   
   # It responds with:
   # This command is in preview. It may be changed/removed in a future release.
   {
   "my-cool-function-app": {
      "accessKey": "1soD6tfrxdLD/8MMEzANYEgA==",
      "accountName": "my-cool-storage-account",
      "mountPath": "/data",
      "shareName": "my-share-name-in-storage-account",
      "state": "Ok",
      "type": "AzureFiles"
      }
   }
   

2. Now, in my Function Apps, I listed the files in some directories:

   import os
   
   files_in_share = os.listdir("/my-share/data")
   logging.info("files: {}".format(files_in_share))
   
   files_in_share2 = os.listdir("/my-share/data/myuser/shared/install")
   logging.info("files in shared/install dir: {}".format(files_in_share2))
   

3. Sure enough, in Application Insights I was able to see the output I was expecting!
