Docker Web Base

A base image for containerized web servers. Work in progress.

Quick overview...

• Built with Packer
• Arch Linux
• Chef Solo
• SSH
• nginx
• Github users

Building the image

Prerequisites

• Arch Linux (host)
• Ruby
• Bundler
• Packer ~v0.7.1

In the root directory...

1. Run bundle install to install the gems
2. Rename variables.example.json to variables.json
3. Set the github_organization variable to the name of your Github organization.
4. Run bundle exec thor packer:build packer.json

The resulting build image will appear at pkg/latest.tar.

Debugging

If the build process fails, try stepping through it with bundle exec thor packer:debug packer.json. While the container is running, you can use nsenter to poke around and see what's wrong.

Launching the image

Import the file to Docker with the docker import subcommand. Tag it however you like.

Launch it wth docker run -it -P -d [-name <NAME>] <IMAGE> /usr/sbin/supervisord -c /etc/supervisord.conf -n.

Root and password authentication are disabled over SSH.

Each public member of your Github organization has a shell account authorized with the public keys they've shared with Github.

Login in with $ ssh [github_username]@[host] -p [port] (Whichever port is mapped to 22)

Or simply use nsenter/docker-enter/etc.

sudo is allowed for Github users. Take advantage of this now to change the default passwords.

Enjoy!
