+## Compose sample application
+### Python/Flask with Nginx proxy and MySQL database

+services:
+  backend:
+    build:
+      context: backend
+      target: builder
+    ...
+  db:
+    # We use a mariadb image which supports both amd64 & arm64 architecture
+    image: mariadb:10-focal
+    # If you really want to use MySQL, uncomment the following line
+    #image: mysql:8
+    ...
+  proxy:
+    build: proxy
+    ...
+```
+The compose file defines an application with three services `proxy`, `backend` and `db`.
+When deploying the application, docker compose maps port 80 of the proxy service container to port 80 of the host as specified in the file.
+Make sure port 80 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`
+
+## Deploy with docker compose
+
+```
+$ docker compose up -d
+Creating network "nginx-flask-mysql_default" with the default driver
+Pulling db (mysql:8.0.19)...
+5.7: Pulling from library/mysql
+...
+...
+WARNING: Image for service proxy 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 should show three containers running and the port mapping as below:
+```
+$ docker compose ps
+NAME                          COMMAND                  SERVICE             STATUS              PORTS
+nginx-flask-mysql-backend-1   "flask run"              backend             running             0.0.0.0:8000->8000/tcp
+nginx-flask-mysql-db-1        "docker-entrypoint.s…"   db                  running (healthy)   3306/tcp, 33060/tcp
+nginx-flask-mysql-proxy-1     "nginx -g 'daemon of…"   proxy               running             0.0.0.0:80->80/tcp
+```
+
+After the application starts, navigate to `http://localhost:80` in your web browser or run:
+```
+$ curl localhost:80
+<div>Blog post #1</div><div>Blog post #2</div><div>Blog post #3</div><div>Blog post #4</div>
+```
+
+Stop and remove the containers
+```
+$ docker compose down
+```
