Create a reusable Volume in Azure IOT Edge Module via Container Create Options about iotedge HOT 2 CLOSED

Hey @tchochunk, here are some good documentations that we have that covers how to configure container create options for IoT Edge modules and modules access to a device's local storage. Let us know if this helps.

@david-emakenemi thank you for the response. I read both those articles and if I copy the HostConfig section from modules access to a device's local storage and use that with my information, it does work. But I dont know what it does. After reading several sites, it seems that Volumes are better than binds but i cant find any documentation on implementing Volumes. While I have a working example, I dont have an understanding of what is happening and the 2 articles are focused on a very small subset of the options available.

I guess I am looking for additional documentation so I will keep searching.
Sincerely, Thank You.

UPDATE: so i made some progress and my conclusion is to carefully read and study the documentation on the docker website https://docs.docker.com/engine/api/v1.30/#tag/Container/operation/ContainerCreate. After this post and following my own advice i came up with the following couple of solutions:

The following config will work (as @david-emakenemi referenced) and the data stored will survive container restarts and deploys:
{
"HostConfig": {
"Mounts": [
{
"Type": "bind",
"Source": "/srv/db/data",
"Target": "/data",
"ReadOnly": false
}
]
}
}

The following also works but creates a volume that maps to the docker managed location (/var/lib/docker/volumes). while i can specify the volume name i did not see a way to specify the source location. maybe i could make the volume separately and specify the location there and just reference that volume here???
{
"HostConfig": {
"Mounts": [
{
"Type": "volume",
"Source": "desiredVolumeName",
"Target": "/data",
"ReadOnly": false
}
]
}
}
