It is because capistrano cannot tell when a script is just waiting for
soemthing to finish, or when it is waiting for input. If you have a
script that needs interaction, you need to capture it's output and
look for the prompt(s) you expect, and then reprompt on the local box,
and send the output back to the server:
run "something that prompts" do |channel, stream, data|
if data =~ /Are you really sure/
puts "Are you really sure?"
response = gets
channel.send_data(response)
else
Capistrano::Configuration.default_io_proc[channel, stream, data]
end
end
If it is the standard deploy:migrate task that you need this kind of
response-handling in, you'll need to reimplement the deploy:migrate
task in your config/deploy.rb (e.g., copy, paste, and tweak).
