Pre-requisities

In Azure subscription:

Build Docker Image

In VS 2019, build the solution and publish it to folder: bin\app.publish

Using Windows Terminal, from Frbar.Azure.WinContainerFileShare.Api folder:

docker build . -t aci-fileshare-poc
docker images
docker run -d -p 8080:80 aci-fileshare-poc

Check that the app is up and running by browsing http://localhost:80.

Run the Container

• From the Azure portal, create an Azure App Service with Windows Container using the pushed image. It has to be Premium Tier, V3.

• Mount the File Share with mount path '/mount' (will be c:/mount from the application perspective).

Accessing the File Share

Using the standard .net API, files/directories can be accessed like from any local directory.
