Normally, I have different mongrel_cluster.yml files but never use
script/spin.
I rewrite deploy:%w(start stop restart) and make tasks for config files.
For example:
== config/deploy.rb
# Common variables
# ...
# Tasks for mongrel
desc "Modified restart task for work ONLY with mongrel cluster"
task :restart do
stop
start
end
desc "Modified start task for work ONLY with mongrel cluster"
task :start do
run "cd #{deploy_to}/current && mongrel_rails cluster::start"
end
desc "Modified stop task for work ONLY with mongrel cluster"
task :stop do
run "cd #{deploy_to}/current && mongrel_rails cluster::stop"
end
# Tasks for config files
namespace :config_files do
require 'erb'
desc "Create config files:database.yml, mongrel_cluster.yml and mailer.rb"
task :default do
database_yml
mongrel_cluster_yml
mailer_rb
local_config_rb
end
desc "Make symlink for config files"
task :symlink do
symlink_database_yml
symlink_mongrel_cluster_yml
symlink_mailer_rb
symlink_local_config_rb
end
desc "Create mongrel_cluster yaml in shared path"
task :mongrel_cluster_yml do
template = File.read(File.join(File.dirname(__FILE__),
"deploy/templates", "mongrel_cluster.erb"))
result = ERB.new(template).result(binding)
run "mkdir -p #{shared_path}/config"
put result, "#{shared_path}/config/mongrel_cluster.yml"
end
desc "Make symlink for mongrel_cluster yaml"
task :symlink_mongrel_cluster_yml do
run "ln -nfs #{shared_path}/config/mongrel_cluster.yml
#{release_path}/config/mongrel_cluster.yml"
end
# More config_files tasks
# ...
# More common tasks
# ...
== config/deploy/templates/mongrel_cluster.erb

More or less :)
