Docker

Dockerfile examples that can be reused for whatever you want.

Script env.sh reads config.yaml, so you don't need to update this script if you want to change something or to add new Docker image. Usage info:

USAGE: ./env.sh option key

Options:
    start
    stop
    restart
    build
    rebuild
    kill
    rm
    rmi

Keys from config.yaml:
    wp
    redis
    mongo
    rails
    ssg
    ghost
    hipache

NOTE: All values in config.yaml except port needs to match directory name where Dockerfile is located.

Tested on Ubuntu 12.04.3

Image layers

Dependencies

Docker 0.6.6 and above:

docker version

Shyaml shell yaml parser:

apt-get -y install python-pip && pip install shyaml

WordPress example

To build WordPress images run:

./env.sh build wp

This command will build all images from config.yaml (wp.images) needed by WordPress.

To start WordPress:

./env.sh start wp

This command will search for dependencies (wp.links) and start them first if they are present. Then it will run new container which will be linked to dependencies. Also it will read port (wp.port) and name (wp.name).

WordPress installation will be available at: http://localhost

Also thanks to Docker VOLUMES you can access to Apache root directory (/var/www) or to MySQL from new container:

docker run -i -t -volumes-from wordpress -link mysql:mysql komljen/wordpress /bin/bash

To access to MySQL database from container:

mysql -h $MYSQL_PORT_3306_TCP_ADDR -u $WP_USER -p$WP_PASS

Hipache example

To build Hipache images run:

./env.sh build hipache

To start Hipache:

./env.sh start hipache

Ghost example

To build Ghost images run:

./env.sh build ghost

To start Ghost:

./env.sh start ghost
