Compose sample application
React application with a Rust backend and a Postgresql database
Project structure:
.
├── backend
│ ├── Dockerfile
│ ...
├── docker-compose.yaml
├── frontend
│ ├── ...
│ └── Dockerfile
└── README.md
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
30b7d9dc4898 react-rust-postgres_backend "cargo run --offline" 37 seconds ago Up 35 seconds 8000/tcp react-rust-postgres_backend_1
0bca0cb682b8 react-rust-postgres_frontend "docker-entrypoint.s…" 42 seconds ago Up 41 seconds 0.0.0.0:3000->3000/tcp react-rust-postgres_frontend_1

After the application starts, navigate to http://localhost:3000 in your web browser to get a colorful message.
Stop and remove the containers
$ docker-compose down
