You've inspired me Jamis. How about the following...
task :group1 do
$group = 1
end
task :group2 do
$group = 2
end
task :group3 do
$group = 3
end
# Note, I have to use a global variable because the tasks can't see
local scope
task :deploy_war_group, :roles => :biz, :only => { :group => $group }
do
...
end
task :deploy_war, :roles => :biz do
end
# then i can control what group through command line
cap prod group1 deploy_war_group
cap prod group2 deploy_war_group
cap prod group3 deploy_war_group
cap prod deploy_war
I can then reuse these groupings for my view tier and cache servers,
etc.
Thanks,
Owen
