Communication between docker container backend and front end

Hello, could you please help me with the following question, what we need to communicate two containers front-end port 80 with angular and nginx and the second container role backend with springboot port 8082, what we will need?

What do you want exactly and what did you try so far? I would not start the whole network configuration process from the beginning. :slight_smile: Short answer: You can use Docker networks and port forwards.
