@ZP-AlwaysWin please comment why this PR is needed. The YAML file in the current state is valid.

Yes ,you are right。The YAML file in the current state is valid. The reason I want to change this Yam file is that the official recommended Yam file is written in this way, and other Yaml files in this code repository are also in this style.

containers:
    - name: mysql
      image: mysql:latest
      env:
        - name: "MYSQL_USER"
          value: "mysql"
        - name: "MYSQL_PASSWORD"
          value: "mysql"
        - name: "MYSQL_DATABASE"
          value: "sample"
        - name: "MYSQL_ROOT_PASSWORD"
          value: "supersecret"
      ports:
        - containerPort: 3306

Current format

spec:
  containers:
    -
      name: mysql
      image: mysql:latest
      env:
        -
          name: "MYSQL_USER"
          value: "mysql"
        -
          name: "MYSQL_PASSWORD"
          value: "mysql"
        -
          name: "MYSQL_DATABASE"
          value: "sample"
        -
          name: "MYSQL_ROOT_PASSWORD"
          value: "supersecret"
      ports:
        -
          containerPort: 3306

Although this Yaml file is valid now, it has poor readability and is prone to indentation errors.
