Supports dotnet watch inside container? about docker-watch

[vandycknick]

Yes this tool is made specifically to fix the issue you just described. I tried to explain the reason for this in my README (it's a bit tough to explain so sr if it didn't make much sense, I'll see if I can revise that).

Most tools work around the issue by falling back to polling for file changes which is also what the dotnet watch command will do when you set the following environment variable DOTNET_USE_POLLING_FILE_WATCHER : https://github.com/aspnet/AspNetCore/tree/master/src/Tools/dotnet-watch#environment-variables . When you use one of the official microsoft aspnet images this will automatically be set for you: https://github.com/dotnet/dotnet-docker/blob/041ee92829af883ff14377c95d4b6773ff483220/2.1/sdk/alpine3.7/amd64/Dockerfile#L26 and thus you will never notice that dotnet watch is falling back to polling.

So you actually have a few options here:

1. Set the DOTNET_USE_POLLING_FILE_WATCHER to true and fall back to polling
2. Use on of the official microsoft aspnet core docker images and not worry about how changes are detected.
3. Use this tool (docker-watch) and it will fix this issue for every mounted volume without changing your docker images. 😄

Hope this helps 👍
