Question

我有一个Rails 5和Capistrano 3应用程序。

我能够将代码推送到git存储库并将其从那里拉出来。

但是，当我尝试通过Capistrano将代码部署到（DigitalOcean）服务器时，我收到以下错误消息：

00:02 git:check
      01 git ls-remote git@bitbucket.org:username/reponame.git HEAD
      01 repository access denied.
      01 fatal: Could not read from remote repository.
      01
      01 Please make sure you have the correct access rights
      01 and the repository exists.

** DEPLOY FAILED

我做了什么：我在我的mac上生成了一个新的SSH密钥，输出位于名为project_name和project_name.pub的文件中。然后我运行了这个命令：

cat ~/.ssh/project_name.pub | pbcopy

并将此密钥代码粘贴到Bitbucket存储库的设置部分＆＃34; SSH密钥＆＃34;。

在Capistrano配置文件中，我有以下内容：

set :ssh_options, {
  keys: %w(/Users/my_name/.ssh/project_name),
  forward_agent: true,
  auth_methods: %w(publickey password),
  port: 22
}

当我运行cap production deploy时，系统会要求我输入密码，之后由于上述错误（Please make sure you have the correct access rights and the repository exists.），部署过程失败。

如何设置密钥/修复部署问题？

Answer 1

看起来你的SSH密钥没有被转发。通常这是因为您的SSH密钥不可用于ssh-agent进行转发。 Github有a good writeup on this，但您可能只需要运行：ssh-add project_name。

您可能还需要更改Github文章所涉及的SSH配置，但我只是从ssh-add开始。

请注意，我基于您的forward agent: true的假设是您尝试通过将本地SSH密钥转发到Github来进行部署，而不是使用应用服务器上存在的部署密钥。如果情况并非如此，并且您的部署密钥位于服务器上，则只需将其设置为false。

Answer 2

希望您在存储库中正确添加了ssh密钥。我认为您正在使用git clone https://user@bitbucket.org/appname.git这样的HTTPS克隆存储库，因为bitbucket是私有存储库，请使用git clone https://user@bitbucket.org/appname.git这样的ssh替换https，请不要记住在小滴中创建ssh密钥时添加密码，请将其留空。希望此帮助对将来的rails爱好者有帮助。
