将 Apollo 客户端和 Apollo 服务器与 Docker 一起使用

Question

Here's a riddle.

I have two containers running in Docker. One holds a create-react-app client using Apollo Client. The other container is a Node.js Apollo Server. The client is able to connect to the server without issue when I use the external IP and the Apollo server's port. However, when I try to use the Docker network, I get ERR_NAME_NOT_RESOLVED on the client side when connecting to the server.

What could be wrong?

Here's the docker-compose.yml

version: "3"
services:
        mornai:
                image: mornai
                container_name: mornai
                ports:
                        - 5000:5000
                volumes:
                        - mornaidata1:/usr/mornai/data
        mornai-web:
                image: mornai-client
                ports:
                        - 3000:3000
                depends_on:
                        - mornai
                environment:
                        REACT_APP_APOLLO_URL: "mornai"
                volumes:
                        - mornaiwebdata1:/usr/mornai-web/data
volumes:
        mornaidata1:
                driver: local
        mornaiwebdata1:
                driver: local

The Apollo client is using the following uri: http://mornai:5000/

The Apollo server (mornai) is definitely listening on port 5000

Docker-compose is definitely creating a default network with two containers, and when I inspect the network I see the 'mornai' service listed

Answer: The browser can't access internal Docker networks. - @DavidMaze

Well that's obvious in hindsight and I'm feeling pretty silly.
