## Compose sample application
|
||
|
|
### PHP server with an Nginx proxy and a MySQL database
|
||
|
|
|
||
|
|
Project structure:
|
||
|
|
```
|
||
|
|
.
|

|
|
[_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
|
||
|
|

|
||
|
|
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
|
||
|
|
```
|
