Docker Links Environment Parser
===============================
[](#docker-links-environment-parser)
[](https://travis-ci.org/texthtml/docker-links)[](https://scrutinizer-ci.com/g/texthtml/docker-links/build-status/master)[](https://packagist.org/packages/texthtml/docker-links)[](https://packagist.org/packages/texthtml/docker-links)
[Docker](http://www.docker.io/) has a feature where you can [link containers together by name](http://docs.docker.io/en/latest/use/working_with_links_names/). For example, you start a redis-server in a docker container and expose the default redis port 6379:
```
$ docker run -p 6379 -d -name redis vagrant/redis-server
```
You then start another containiner running a php-fpm web service that needs to access this redis server:
```
$ docker run --link redis:db -d php:fpm
```
Docker will internally hook up these the two containers and pass host and port information to the php-fpm web service via environment variables:
```
DB_NAME=/romantic_lumiere/db
DB_PORT=tcp://172.17.0.5:6379
DB_PORT_6379_TCP=tcp://172.17.0.5:6379
DB_PORT_6379_TCP_ADDR=172.17.0.5
DB_PORT_6379_TCP_PORT=6379
DB_PORT_6379_TCP_PROTO=tcp
```
This library provides a helper `parseLinks` that will parse these environment variables into easily navigable PHP objects.
### Install
[](#install)
Install `docker-links` via [composer](https://getcomposer.org/)
```
$ composer require texthtml/docker-links
```
### Example Usage
[](#example-usage)
Consider a container that accesses three external services on two other containers. The first container exposes redis on port 6379 and postgres on 6500. The second container exposes redis on port 6379.
```
DB_NAME=/romantic_lumiere/db
DB_PORT=tcp://172.17.0.5:6379
DB_PORT_6379_TCP=tcp://172.17.0.5:6379
DB_PORT_6379_TCP_ADDR=172.17.0.5
DB_PORT_6379_TCP_PORT=6379
DB_PORT_6379_TCP_PROTO=tcp
DB_PORT_6500_TCP=tcp://172.17.0.5:6500
DB_PORT_6500_TCP_ADDR=172.17.0.5
DB_PORT_6500_TCP_PORT=6500
DB_PORT_6500_TCP_PROTO=tcp
DB_REDIS_NAME=/romantic_lumiere/db_redis
DB_REDIS_PORT=tcp://172.17.0.2:6379
DB_REDIS_PORT_6379_TCP=tcp://172.17.0.2:6379
DB_REDIS_PORT_6379_TCP_ADDR=172.17.0.2
DB_REDIS_PORT_6379_TCP_PORT=6379
DB_REDIS_PORT_6379_TCP_PROTO=tcp
```
Parse with `docker-links`:
```
$links = \TH\Docker\Links::buildFrom($_ENV);
// $links can be used as an array
echo count($links), PHP_EOL; // 2
foreach ($links as $name => $link) {
echo $name, PHP_EOL; // /romantic_lumiere/db, /romantic_lumiere/db
}
// each link is an instanceof [Link](test)
$link = $links['/romantic_lumiere/db'];
echo $link->mainPort()->address(), PHP_EOL; // 172.17.0.5
echo $link->mainPort()->protocol(), PHP_EOL; // TCP
echo $link->mainPort()->number(), PHP_EOL; // 6379
echo $link->env()['USERNAME'], PHP_EOL; // username
echo $link->env('PASSWORD'), PHP_EOL; // password
echo $link->env('SOMETHING_ELSE'), PHP_EOL; // NULL
echo $link->env('SOMETHING', 'default value'), PHP_EOL; // default value
```
