Example host special configuration

Custome host config and merge by common configuration

yaml

hosts:
  - 10.110.110.12
  - 10.110.110.78
spec:
  - addr: 10.110.110.92
    user: <special user name>
  - addr: 192.168.1.134
    password: <special password>
  - addr: 10.110.110.123:<special port>
    cmd: <special command>
port: <common port>
user: <common user>
password: <common password>

example.yaml

hosts:
  - 10.110.110.12
  - 10.110.110.78
spec:
  - addr: 10.110.110.78
    user: bar
