Chef & git ssh 身份验证问题。比特桶

Question

编辑：我的工作解决方案基于以下答案。

    include_recipe 'chef-vault'
include_recipe 'build-essential'

#installation of git
package 'git' do
  action :install
end

repo = 'emrwebapp'

application "/root/#{repo}" do
  owner 'root'
  group 'root'
  git "/root/#{repo}" do
    repository "git@bitbucket.org:sgreen22/#{repo}.git"
    deploy_key chef_vault_item(:credentials, 'git')['bitbucketKey']
  end
end

'-1 guy' - 粉丝！现在祝你有美好的一天。

我是 Chef 的新手，我正在尝试克隆一个 repo 以完成我自己设定的一个简单的学习任务。

我已经学习了很多教程并尝试了很多建议，但由于公钥错误仍然无法克隆 repo。

我正在本地终端上复制步骤，以确保我没有弄乱 url 或任何东西。

我已经：

创建了一个新密钥，确保没有设置密码，将公钥上传到 bitbucket 并使用 ssh -T hg@bitbucket.org 从本地机器测试密钥。

然后，我将此密钥添加到厨师保险库，并验证它存在且可见。

然后使用 chef 我将密钥复制到客户端节点上的某个位置，然后尝试克隆 repo。

有趣的是，当我在客户端节点上运行 hg@bit... 命令时，系统会提示我输入密码，然后按回车键失败。

我已经对本地和客户端的文件进行了分类，并且可以确认它们是正确的。
我在客户端节点上以 root 身份运行，并将密钥放在 /root/.ssh 中，再次通过 pwd 验证。

在客户端上运行详细的 hg@bit... 命令再次要求输入密码，输入权限被拒绝。

非常感谢任何帮助。以下是日志和厨师食谱，谢谢。

Answer 1

作为对上述问题的一种更简单的解决方案，application_git cookbook 有一个资源可以为您处理所有这些，只需提供 deploy_key 值，它会处理其余的事情。

Answer 2

这是一个如何使用 ssh 包装器从 GitHub 更新 Chef 存储库的示例。

repo = 'emrwebapp'
wrapper = "git_wrapper_#{repo}.sh"

file wrapper do
    owner 'ec2-user'
    group 'ec2-user'
    mode 00755
    content "#!/bin/sh\nexec /usr/bin/ssh -o UserKnownHostsFile=/dev/null "\
    '-o StrictHostKeyChecking=no '\
    "-i /home/ec2-user/.ssh/id_rsa \"$@\""
end

git repo do
    repository "git@bitbucket.org:sgreen22/#{repo}.git"
    reference 'master'
    ssh_wrapper wrapper
    user 'ec2-user'
    group 'ec2-user'
end

最后，您将获得 git_wrapper_emrwebapp.sh 由厨师生成的文件，该文件将用于 ssh_wrapper 和 git resource。

SSH 包装文件如下所示：

#!/bin/sh 
exec /usr/bin/ssh -o UserKnownHostsFile=/dev/null
StrictHostKeyChecking=no -i /home/ec2-user/.ssh/id_rsa "$@"
