Rails - Capistrano - 为什么deploy.rb中的默认重启配方有“wait：5”

Question

我想知道为什么Capistrano 3 文件:restart中的默认配方有一个参数？deploy.rbwait: 5

每次重新启动之间是否有特殊原因要等待 5 秒？

desc 'Restart application'
   task :restart do
     on roles(:app), in: :sequence, wait: 5 do
       execute :touch, release_path.join('tmp/restart.txt')
     end
   end

Answer 1

这是在capistrano 3 的发行说明中定义的

on :all, in: :sequence, wait: 15 do
  # This takes all servers, in sequence and waits 15 seconds between
  # each server, this might be perfect if you are afraid about
  # overloading a shared resource, or want to defer the asset compilation
  # over your cluster owing to worries about load
end
