kubernetes YAML文件的使用

key：{key1: value1,key2: value1}

或者

key：
    key1：value1
    key2：value2

websites:
  YAML: yaml.org 
  Ruby: ruby-lang.org 
  Python: python.org 
  Perl: use.perl.org

表示成json格式就是：
  websites: {
    YAML: 'yaml.org',
    Ruby: 'ruby-lang.org',
    Python: 'python.org',
    Perl: 'use.perl.org' 
  } 

- A
- B
- C

表示成数组是：[A,B,C]

students:
    -
        id: 1
        name: zhangsan
        age: 12
    -
        id: 2
        name: lisi
        age: 15

表示成数组是：
students:[{id: 1,name: zhangsan,age: 12},{id: 2,name: lisi,age: 15}]

数组中的元素又是一个key-value结构的dict

yaml格式的文件
nodes:
  - name: jobE
    type: command
    config:
      command: echo "This is job E"
    dependsOn: 
      - jobD

  - name: jobD
    type: command
    config:
      command: echo "This is job D"
    dependsOn:
      - jobA
      - jobB
      - jobC


表示成json格式就是：
{
    "nodes":[
        {
            "name":"jobE",
            "type":"command",
            "config":{
                "command":"echo \"This is job E\""
            },
            "dependsOn":[
                "jobD"
            ]
        },
        {
            "name":"jobD",
            "type":"command",
            "config":{
                "command":"echo \"This is job D\""
            },
            "dependsOn":[
                "jobA",
                "jobB",
                "jobC"
            ]
        }
    ]
}
