Dockerfile doesn’t seem to run while debugging in Visual Studio 2019

The past few weeks i’ve been working on a project which is built in C# .NET Core in Visual Studio 2019. I enabled Docker support and am using docker-compose to spin up 2 containers (it starts an identityserver4 and webapi). I’ve created dockerfiles for both projects and created a docker-compose file for starting up the service stack.

The issue i’m running into is that when i run the docker-compose in Visual Studio Debugging mode, it doesnt seem to run my Dockerfile. In the lasts steps in my Dockerfile, I copy some files around and execute a command. These do not get run. However when I use docker build in my commandline, it DOES execute those Dockerfile commands.

Attached my 2 docker files & docker compose.

Web API Dockerfile:
