Chef-Solo Capistrano Bootstrap

by Mike Smullin mike@smullindesign.com

Utilize Capistrano to automatically bootstrap any remote server for Chef-Solo via SSH using a single command.

Installation

  • Git clone the blank Opscode Chef Cookbook Repository to your local machine

    git clone http://github.com/opscode/chef-repo

  • Reset the git history

    rm -rf .git && git init .

  • Make a special directory for containing all your dna.json files

    mkdir ./dna/ && touch ./dna/example-node.json

  • Install Capistrano gem on the local machine either as a system gem or using bundler

    gem install capistrano

  • Git clone or wget the Capfile into your cookbook repo root dir

    wget http://github.com/mikesmullin/Chef-Solo-Capistrano-Bootstrap/raw/master/Capfile

  • Write your cookbook recipes and roles

Usage

  • Execute the Capistrano Chef Bootstrap task

    cap chef:bootstrap <dna> <remote_host>

  • Enjoy!

Example

cap chef:bootstrap <dna> <remote_host>

There are other commands you can find by cap -vT.

For eaxmple, during development, it is handy to use:

 cap chef:resolo <dna> <remote_host>

Which will push out your latest cookbook plus the dna.json and execute chef-solo on it.

When you are done, you can remove all traces of Chef with:

 cap chef:clean <dna> <remote_host>

Or if you want to nuke and pave to be sure old recipes are not causing problems:

 cap chef:clean_solo <dna> <remote_host>

If you are like me you enjoy provisioning a new Rackspace VPS and issuing this command to automatically create my users, groups, and copy ssh keys over for a passwordless ssh session going forward:

 cap chef:init_server <new_server_remote_ip>

Future goals

Is it possible that with the power of Ruby Expect, either Capistrano or Chef could be made better so that only one or the other is ultimately necessary?
