Taking it further... you can also then dynamically name your tasks
(which is slightly crazy, but hey...)
desc "Just spitting out some IPs from the command line"
task (ENV["TASK_NAME"] || :spit_addresses).to_sym do
ENV["ADDRESSES"].split(",").each {|a| puts a }
end
That task will then be named whatever you pass in for TASK_NAME,
defaulting to :spit_addresses, e.g.:
cap funkytown TASK_NAME=funkytown ADDRESSES=10.0.0.1,10.0.0.2
I guess the point (since this doesn't directly answer your question)
is that you can load your arguments from the command line, and set/
change tasks/roles and their deps at runtime according to your needs
with a lil' Ruby.
