Yaml Kubernetes:验证数据时出错：发现v1.PodSpec的无效字段env；

我使用下面的yaml文件创建pod，kubectl命令给出以下错误

如何更正此错误消息

apiVersion: v1
kind: Pod
metadata:
  name: command-demo
  labels:
    purpose: demonstrate-command
spec:
  containers:
  - name: command-demo-container
    image: debian
    command: ["printenv"]
    args: ["HOSTNAME", "KUBERNETES_PORT"]
  env:
  - name: MESSAGE
    value: "hello world"
    command: ["/bin/echo"]
    args: ["$(MESSAGE)"]

kubectl create -f commands.yaml
error: error validating "commands.yaml": error validating data: found invalid field env for v1.PodSpec; if you choose to ignore these errors, turn validation off with --validate=false

请遵循本页中的示例

谢谢

语法正确的YAML会导致kubernetes的数据结构不正确。在YAML中，缩进会影响数据的结构。看

我认为这应该是正确的：

apiVersion: v1
kind: Pod
metadata:
  name: command-demo
  labels:
    purpose: demonstrate-command
spec:
  containers:
  - name: command-demo-container
    image: debian
    command: ["printenv"]
    args: ["HOSTNAME", "KUBERNETES_PORT"]
    env:
    - name: MESSAGE
      value: "hello world"
    command: ["/bin/echo"]
    args: ["$(MESSAGE)"]
