jsonnull / LEMH

PHP applications running on docker using the fast, performant LEMH stack—Linux, nginx, MySQL, HHVM.

Linux + nginx + MySQL + HHVM

jsonnull/LEMH is a docker image that makes it easy to spin up a modern LEMH stack for PHP applications. A 512mb DigitalOcean droplet easily handles minimal deployments of applications like Wordpress and esoTalk—LEMH serves pages scary fast and has a low memory footprint.

This repository is home to the docker image as well as several supported configurations for PHP applications running on LEMH.

App	Purpose	Version
Wordpress	blogging platform	4.1.2
esoTalk	forum software	b2a1884

To deploy one of these apps just clone this repo, navigate to the corresponding directory in examples, and run docker-compose up.

For info on how to install and use docker-compose see https://docs.docker.com/compose/install/.

Running an app with docker-compose

Use docker-compose to declare the environment variables and start the containers.

First, edit docker-compose.yml. Here's a good starting point:

data:
  image: cogniteev/echo
  volumes:
   - /var/www
   - /var/lib/mysql

db:
  image: mariadb:latest
  ports:
   - "3306:3306"
  volumes_from:
   - data
  environment:
   - MYSQL_ROOT_PASSWORD=test
   - MYSQL_USER=app
   - MYSQL_PASSWORD=test
   - MYSQL_DATABASE=myapp

web:
  image: jsonnull/lemhpress
  links:
   - db
  ports:
   - "80:80"
  volumes_from:
   - data
  environment:
   - DB_USER=app
   - DB_PASSWORD=test
   - DB_NAME=myapp

Then run docker-compose up -d to start the daemonized containers. The server will attempt to serve PHP files from /var/wordpress.

Alternate Usage

Just run two containers with docker.

docker run -d --name db_1 -e "MYSQL_DATABASE=wordpress" -e "MYSQL_ROOT_PASSWORD=test" -p 3306:3306 mariadb:latest
docker run -d --name web_1 --link db_1:db_1 -e "DB_USER=root" -e "DB_PASSWORD=test" -p 80:80 -v "/var/www" jsonnull/lemhpress

Roadmap

Want to know what to help on? Here are some things I have in mind for this project:

• Maintain configurations for a number of PHP applications. Configurations are pinned to a specific tag of the LEMH image, so the base image can progress without breaking existing applications, and the applications can migrate to newer images at their own pace.
• Better configuration management—right now nginx and hhvm configurations are baked into the base image with no support for configuration of basic options via environment variables. Also, examples could show application-specific customization for nginx and HHVM if necessary.
