Hi,
I'd like to run a local task before anything else runs (to populate my
roles). Is there a callback I can use to do that?
eg. I'm doing something like this:
role :partition do end
role :queue_processor do end
role :web do end
# Custom tasks for our local machine.
namespace :local do
desc <<-DESC
Populate all roles
DESC
task :populate_roles do
enum_partition
enum_queue_processor
end
end
task :enum_partition do
desc "Enumerate hosts that are partition servers from puppet DB"
cmd = 'sc_hosts.rb --class profile::partition'
capture(cmd).each do |host|
next unless host.chomp
role(:partition, host)
role(:web, host)
end
end
task :enum_queue_processor do
desc "Enumerate hosts having $HOME/queue_processor"
cmd = 'sc_hosts.rb --class app::tree::queue_processor'
capture(cmd).each do |host|
next unless host.chomp
role(:queue_processor, host)
role(:web, host)
end
end
What I'm looking for is a suitable callback to run populate_hosts before
any other tasks, ie.
before '????????', 'local:populate_roles'
Can anyone suggest what I might use?
R.
