+## Compose sample application
+### PHP server with an Nginx proxy and a MySQL database
+
+Project structure:
+```
+.
+├── backend
+│   ├── Dockerfile
+├── db
+│   └── password.txt
+├── docker-compose.yaml
+├── proxy
+│   ├── conf
+│   └── Dockerfile
+├── src
+│   ├── index.php
+└── README.md
+```
+
+[_docker-compose.yaml_](docker-compose.yaml)
+```
+services:
+  backend:
+    build: backend
+    ...
+  db:
+    image: mysql:8.0.19
+    ...
+  proxy:
+    build: proxy
+    ports:
+    - 80:80
+    ...
+```
+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 in use.
+
+## Deploy with docker-compose
+
+```
+$ docker-compose up -d
+Creating nginx-php-mysql_db_1 ... done
+Creating nginx-php-mysql_backend_1 ... done
+Creating nginx-php-mysql_proxy_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
+2244050972fc   nginx-php-mysql_proxy     "/docker-entrypoint.…"   51 seconds ago   Up 49 seconds   0.0.0.0:80->80/tcp    nginx-php-mysql_proxy_1
+75353040cb38   nginx-php-mysql_backend   "docker-php-entrypoi…"   51 seconds ago   Up 50 seconds   9000/tcp              nginx-php-mysql_backend_1

+```
+
+After the application starts, navigate to `http://localhost:80` in your web browser or run:
+```
+$ curl localhost:80
+<h1>hello world in php!</h1>
+```
+
+Stop and remove the containers
+```
+$ docker-compose down
+```
