Saltstack smtp.send_msg 返回属性错误

Question

我设置了一个信标，用于跟踪 Ubuntu Server 16.04 上所有 Ubuntu Server 16.04 minions 的磁盘使用情况。我们想要一个反应器，当磁盘 space 达到某个点时，它会向我们发送电子邮件。本题侧重于master发送邮件的能力。当我运行在 salt-master 上执行以下命令时：

sudo salt-call smtp.send_msg 'email@email.com' 'Test message 3' subject='Test subject 3' profile='smtp-default'

我得到以下结果：

[ERROR   ] An un-handled exception was caught by salt's global exception handler:
AttributeError: 'str' object has no attribute 'get'
Traceback (most recent call last):
  File "/usr/bin/salt-call", line 11, in <module>

    ret['return'] = func(*args, **kwargs)

这是我的 salt --versions-report master 的输出，returns 错误：

我已经卸载并重新安装了 salt-master 和 salt-minion，并且更新了 Python 和 salt-master。我还创建了另一个 salt-master，它运行遇到了同样的问题。对此有何修复或解决方案？

Answer 1

我发现错误与安装的 Python 库无关，也与我的系统是否更新无关。我发现我没有设置 SMTP 服务器，我需要创建一个 SMTP 邮件服务器或有一个可访问的 SMTP 邮件服务器，以便发送电子邮件作为反应器系统的通知。我发现解决方案是设置一个 SMTP 邮件服务器，然后在 /etc/salt/minion.d 目录中创建一个引用 SMTP 邮件服务器的 .conf 文件，如下所示：

smtp-default:
  smtp.sender: mail@example.com
  smtp.server: 0.0.0.0
  smtp.tls: false

在创建了一个与上述类似的 .conf 文件和引用状态文件的函数声明的 salt-call 命令的配置文件后，我能够将电子邮件发送到所需的地址。
