Rails和数字海洋Ubuntu Docker的问题

我一直在关注这个教程： https : //www.digitalocean.com/community/tutorials/deploying-a-rails-app-on-ubuntu-14-04-with- capistrano-nginx-and-puma

但是我得到这个错误：root @ demo：〜/ app＃cap demo deploy：initial [弃用通知]默认情况下，未来版本的Capistrano不会加载Git SCM插件。 为了消除这个弃用警告，在require "capistrano/deploy"后将以下内容添加到您的Capfile中：

需要“capistrano / scm / git”install_plugin Capistrano :: SCM :: Git

（回溯限制为导入的任务）cap中止！ SSHKit :: Runner :: ExecuteError：在主机xxxx上执行时发生exception：拒绝连接 – 连接（2）为“xxxx”端口5000

Errno :: ECONNREFUSED：拒绝连接 – 连接（2）“xxxx”端口5000

我一直在研究几个小时，不知道如何解决这个问题，因为我找不到公式化的答案。

下面是deploy.rb
