getting capistrano to work

[ruud]

Versions:

• Ruby 1.9.2
• Capistrano3.0.1
  
• (Rake Version: 10.3.2

hello group,
I just wanted to get the basics of capistrano to understand how and if I can use it for my project.

However, I am reading and trying for quite some time and I have not created a single capfile that did anything without stacktraces. Can you please assist me so that I can get started?

Based on a very basic tutorial, my capfile contains right now:

set :username, "ruud"
set :host, "localhost"

desc "simple test"
task :search, :hosts => "#{username}@#{host}" do
      run "ls -x1 /usr/lib | grep -i xml"
end

and cap reports me this:
SZ cap search
cap aborted!
NameError: undefined local variable or method `username' for main:Object
/data/ruby/capistrano/capfile:1:in `<top (required)>'
/export/home/rdgon/.rvm/gems/ruby-1.9.2-p290/gems/capistrano-3.0.1/lib/capistrano/application.rb:22:in `load_rakefile'

Do you know what I am missing?
Maybe I am not using the right tutorial. If someone can recommend me a step by step tutorial for understanding the basics, I would be very grateful.

Use fetch(:username), and then ask yourself why you are using capistrano helpers, for normal variables :-) chef Google for "sshkit examples" probably a better place to start

Hi Haani,
thanks for the tutorial. Very helpful. Still got some things that are somewhat not working as expected, but that is part of the learning process ;)
