I\'m running a react boilerplate app within a docker container, hosted Azure Web App Containers.
Locally, I spin the app up with:
docker run -p 3000:3000 4
User 4c74356b41 is correct.
In APPLICATION SETTINGS you need to set the key / value pair WEBSITES_PORT.
For some reason it's not working on this image, but I went through another example and did it all through the command line, and it worked fine.
