## Compose sample application
### React application with a Rust backend and a Postgresql database
Project structure:
```
.
├── backend
│   ├── Dockerfile
│   ...
├── docker-compose.yaml
├── frontend
│   ├── ...
│   └── Dockerfile
└── README.md
```
[_docker-compose.yaml_](docker-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
Building backend
...
Successfully tagged react-rust-postgres_frontend:latest
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`.
Creating react-rust-postgres_frontend_1 ... done
Creating react-rust-postgres_db_1 ... done
Creating react-rust-postgres_backend_1 ... done
```
## 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
1611961bf3d1 postgres:12-alpine "docker-entrypoint.s…" 42 seconds ago Up 36 seconds 0.0.0.0:5432->5432/tcp react-rust-postgres_db_1
```
After the application starts, navigate to `http://localhost:3000` in your web browser to get a colorful message.
