## Compose sample application
### PHP application with Apache2
Project structure:
```
.
├── docker-compose.yaml
├── app
   ├── Dockerfile
   └── index.php
```
[_docker-compose.yaml_](docker-compose.yaml)
```
services:
web:
build: app
ports:
- '80:80'
volumes:
- ./app:/var/www/html/
```
## Deploy with docker-compose
```
$ docker-compose up -d
Creating network "php-docker_web" with the default driver
Building web
Step 1/6 : FROM php:7.2-apache
...
...
Creating php-docker_web_1 ... done
```
## Expected result
Listing containers must show one container running and the port mapping as below:
```
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
2bc8271fee81 php-docker_web "docker-php-entrypoi…" About a minute ago Up About a minute 0.0.0.0:80->80/tc php-docker_web_1
```
After the application starts, navigate to `http://localhost:80` in your web browser or run:
```
$ curl localhost:80
Hello World!
```
Stop and remove the containers
```
$ docker-compose down
```
