# Docker runnable PHP Application with HAProxy

Usable with docker-machine. Based on the Heroku PHP Docker image.

Load balanced by HAProxy.

**Note:**


Due to the changes to links and networks in Docker 1.6 and docker-compose,

the haproxy currently needs to be removed and recreated for link-changes

(f.e. scale events) to be picked up.

## Deployment

1. Create a docker machine with your preferred driver

2. Connect your local Docker client to the machine `eval $(docker-machine env $name)`

3. Check the connectivity (`docker ps` should be usable and `docker-machine ls`

   should mark the machine active)

4. Deploy the app with `docker-compose up -d lb web`

5. Check the IP of the docker machine on port 80. It should show a nice `phpinfo` page

6. Check the IP of the docker machine on port 1936. Authenticate with `auth`/`auth`,

   you should see the haproxy stats page with one backend

7. Scale your app `docker-compose scale web=3`

8. Reload HAProxy by stopping, removing and restarting the container

   ```

   # Stop the balancer

   docker-compose stop lb

   # Remove the old balancer

   docker-compose rm lb

   # Bring the balancer back up

   docker-compose up --no-deps -d lb web

   ```

9. Reload the haproxy stats page. You can see 3 backends now.
