Question

I have seen the docs which gave the volume mount option but I didn't understand how to specify the exact directory and what is the target and source container

Hello @Anurag Shelar ,

Microsoft supports a Blob storage module on Azure IoT edge.

This module has two main capabilities:

1. providing an Azure-Blob-storage-account-like API for other modules so files can be stored locally on the edge
2. files/blobs which are stored locally by the Blob module can be synced with a storage account in the cloud

An example of using this module is seen here.

It seems you are looking for a way to send images from a folder to the cloud.

The Microsoft Blob storage container is not checking folders itself. you need to provide it with the files you want to sync to Azure using that API.

For this to happen, you should implement a custom 'file system watcher' module.

In your deployment manifest use add below in your create Options in edge Hub
"HostConfig": {
"Binds": [
"/etc/aziot/storage/:/storage/"
]
}

In above example ,your linux machine have a folder "/etc/aziot/storage/ is binded with :/storage/ in docker container.
