Knife OpenStack Launcher

A knife-openstack wrapper with support for YAML profiles

Installation

Add this line to your Chef repository's Gemfile:

gem 'knife-openstack_launcher',
    :git => '[email protected]:greenalto/knife-openstack_launcher.git'

And then execute:

$ bundle

Usage

Create a config/openstack.yml file in your Chef repository. Here's an example:

profiles:
  instance:
    security_groups:
      - "default"
    run_list:
      - "role[base]"
    flavor: "t1.micro"
    image: "ami-f5998981"
    distro: "chef-full"

To bootstrap an "instance" server with the right security group, flavor and image, launch from your Chef repository:

knife openstack server from profile instance.example.com --profile=instance

You can specify the path to a YAML config file:

knife openstack server from profile instance.example.com --profile=instance \
  --yaml-config=/path/to/config.yml

You can override anything that can be set when bootstrapping a node using knife-openstack using the YAML profiles. See ec2_base and ec2_server_create for a complete reference.

You can also add any command-line switch from knife ec2 server create --help. For example, if you want to create a more powerful SVN server in another region as a one-time action:

knife openstack server from profile svn_us.example.com --profile=svn \
  --region=us-west-1 --flavor=m1.small

If you don't specify something in the profile, it is going to be taken from your .chef/knife.rb or the defaults from the knife-ec2 plugin. For example:

knife[:flavor]   = 'm1.small'
knife[:ssh_user] = 'ubuntu'
