OBD 中的配置文件有其固定格式，下面结合示例讲解配置文件中不同模块的含义。

```yaml
# Only need to configure when remote login is required
user:   # ssh 登录配置
  username: your username
  password: your password if need
  key_file: your ssh-key file path if need
  port: your ssh port, default 22
  timeout: ssh connection timeout (second), default 30
