ruby-on-rails - Capistrano 失败，因为它无法连接到远程 git 存储库

Question

我正在尝试使用 Capistrano 3.x 进行部署。

我在 ~/.ssh/config 文件中配置了代理转发:

Host git-codecommit.*.amazonaws.com
  Hostname xxxx
  ForwardAgent yes
  IdentityFile /path/to/codecommit_rsa

我为我的服务器连接做了同样的事情 ForwardAgent yes还。

我验证了我的服务器还允许在/etc/ssh/sshd_config 文件中进行代理转发:

AllowAgentForwarding yes

Please make sure you have the correct access rights
and the repository exists.

我在这里想念什么？

您需要让 Capistrano 知道您希望它转发您的本地 key 。这可以通过进入您项目的 config/deploy.rb 来完成。并添加这一行:

ssh_options[:forward_agent] = true

IIRC，Capistrano 通过 SSHKit 远程执行命令, 所以即使你调用 ssh-agent并在本地添加一个 key ，我不能说它是否会持续到下一个命令。
