Compose sample application

React application with a Rust backend and a Postgresql database

Project structure:

compose.yaml

services:
  backend:
    build: backend
    ...
  db:
    image: postgres:12-alpine
    ...
  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
Creating network "react-rust-postgres_default" with the default driver

WARNING: Image for service frontend was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`.

Expected result

Listing containers must show three 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 to get a colorful message.

Stop and remove the containers
