SpaceCadet

SpaceCadet is a library written in Ruby for interacting with the Rackspace Cloud Load Balancers. The library itself uses the fog gem, which is a very popular Ruby library for interacting with all of the different cloud providers (including Rackspace).

SpaceCadet is released under the Apache 2.0 license. See the LICENSE file for full the full details of the license.

Because this library is meant to speed up deploys, and it's a little "special"...

It's not meant to be pretty, clean, or re-usable. This library was written with one purpose in mind: being able to change a single backend node from ENABLED to DRAINING within multiple LBs.

Also: (Rack)space.

gem 'dd_spacecadet', git: 'git@ddgit.me:EngOps/spacecadet.git'

Here's an example of using the library while interacting with the DFW region:

require 'dd_spacecadet'

env = 'dfw-prod'
region = 'DFW'

DoubleDutch::SpaceCadet::Config.register(
  env, ENV['RS_CLOUD_USERNAME'], ENV['RS_CLOUD_KEY'], region
)

dfw_prod = DoubleDutch::SpaceCadet::LB.new(env)

# search for an LB by its label, in this example "prod-lb"
# if multiple LBs match it will use *ALL* of them
dfw_prod.find_lb_and_use('prod-lb')

# gets the status of each LB and its nodes
# you can use dfw.print_status to print the info to stdout with formatting
dfw.status

dfw.update_node('node01', :draining)

dfw.update_node('node01', :enabled)
