## Compose sample application

### React application with a NodeJS backend and a MySQL database
|

Project structure:

|

|

# We use a mariadb image which supports both amd64 & arm64 architecture
|
||

# If you really want to use MySQL, uncomment the following line
|

#image: mysql:8.0.27

||
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.
|
||
|
||
> ℹ️ **_INFO_**
|
||
> For compatibility purpose between `AMD64` and `ARM64` architecture, we use a MariaDB as database instead of MySQL.
|
||
> You still can use the MySQL image by uncommenting the following line in the Compose file
|
||
> `#image: mysql:8.0.27`
|
||
|
||
## Deploy with docker-compose
|
||
|
||
```
|
||
$ docker-compose up -d
|
||
Creating network "react-express-mysql_default" with the default driver

## Expected result
|
||
|
||
Listing containers must show containers running and the port mapping as below:
|
||
```
|
||
$ docker ps
|
||
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
||
f3e1183e709e react-express-mysql_frontend "docker-entrypoint.s…" 8 minutes ago Up 8 minutes 0.0.0.0:3000->3000/tcp react-express-mysql_frontend_1
|
||
9422da53da76 react-express-mysql_backend "docker-entrypoint.s…" 8 minutes ago Up 8 minutes (healthy) 0.0.0.0:80->80/tcp, 0.0.0.0:9229-9230->9229-9230/tcp react-express-mysql_backend_1

||

|
||
```
|
||
|
||
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
|
||
```
|
||
$ docker-compose down
