docker-compose.yaml

services:
  backend:
    build: backend
    ports:
      - 80:80
      - 9229:9229
      - 9230:9230

    image: mysql:8.0.19
    ...
  frontend:
    build: frontend
    ports:
    - 3000:3000
    ...

The compose file defines an application with three services frontend, backend and db. When deploying the application, docker-compose maps port 3000 of the frontend service container to port 3000 of the host as specified in the file. Make sure port 3000 on the host is not already being in use.

Deploy with docker-compose

$ docker-compose up -d

Expected result

Listing containers must show containers running and the port mapping as below:

$ docker ps
CONTAINER ID        IMAGE                          COMMAND                  CREATED             STATUS                   PORTS                                                  NAMES

After the application starts, navigate to http://localhost:3000 in your web browser.

The backend service container has the port 80 mapped to 80 on the host.

$ curl localhost:80
{"message":"Hello from MySQL 8.0.19"}

Stop and remove the containers
