ssh - 使用 ansible 执行 ssh-add 会引发错误

Question

我正在尝试使用 Ansible 为 ssh 连接创建基础设施。

- name: Copy ssh key to each server
  copy: src=static_folder_key dest=/home/ec2-user/.ssh/ mode=0600

- name: Enable ssh Agent
  shell: eval $(ssh-agent -s)

- name: Adding ssh key for static forlder project
  shell: ssh-add /home/ec2-user/.ssh/static_folder_key
  sudo: True

我创建了一个新的 ssh key 并复制到我的服务器。然后我执行代理，稍后我添加新 key 以允许连接。但是当我执行 ansible 时，我收到了这个错误。

TASK: [git | Adding ssh key for static forlder project] *********************** 
failed: [admin_vehicles] => {"changed": true, "cmd": "ssh-add /home/ec2-user/.ssh/static_folder_key", "delta": "0:00:00.004346", "end": "2015-08-12 15:05:00.878208", "rc": 2, "start": "2015-08-12 15:05:00.873862", "warnings": []}

FATAL: all hosts have already failed -- aborting

如果我手动执行此操作，则一切正常。

ssh-add /home/ec2-user/.ssh/static_folder_key 
Identity added: /home/ec2-user/.ssh/static_folder_key (/home/ec2-user/.ssh/static_folder_key)

那么有什么提示吗？也许我在我的剧本任务中遗漏了一些东西？

对此的解决方案是调用 eval "$(ssh-agent)"之前ssh-add .最初我尝试了两个 Ansible 任务，但它以同样的方式失败，因为它们是原子的，无法保持状态。我最终得到的最终解决方案是在单个任务中调用这两个命令，如下所示:

  - name: Evaluating the authentication agent & adding the key...
    shell: |
      eval "$(ssh-agent)"
      ssh-add ~/.ssh/id_rsa_svn_ssh
