【问题描述】：
昨天在私人笔记本上安装了kubernetes microk8s，学习kubernetes， 但即使在第一个带有 PersistentVolume 的简单文件上，我也会遇到很多验证错误，
我已经从以下来源在 Ubuntu 上安装了 microk8s： https://microk8s.io/?_ga=2.70856272.1723042697.1642604373-620897147.1642604373v
问题是我第一次想创建 pv：
apiVersion: v1
kind: PersistentVolume
metadata:
name: redis-pv
spec:
storageClassName: ""
capacity:
storage: 1Gi
accessModes:
- ReadWriteOnce
hostPath:
path: "/mnt/data"
我得到以下错误：
kubectl apply -f pv-data.yml -n testing
error: error validating "pv-data.yml": error validating data: [ValidationError(PersistentVolume): unknown field "accessModes" in io.k8s.api.core.v1.PersistentVolume, ValidationError(PersistentVolume): unknown field "name" in io.k8s.api.core.v1.PersistentVolume, ValidationError(PersistentVolume): unknown field "path" in io.k8s.api.core.v1.PersistentVolume, ValidationError(PersistentVolume): unknown field "storage" in io.k8s.api.core.v1.PersistentVolume, ValidationError(PersistentVolume): unknown field "storageClassName" in io.k8s.api.core.v1.PersistentVolume]; if you choose to ignore these errors, turn validation off with --validate=false
有人可以帮我吗？也许我没有正确安装 microk8s ？因为这是一个非常简单的 yaml 文件。
我也想附上 microk8s 的状态：

【问题讨论】：
-
yaml 对缩进非常严格，原因是它允许嵌入其他类型的内容，只能使用缩进来知道事情的开始和结束。
-
要非常小心，因为如果你弄错了缩进，你会得到很多不同的错误和事情不起作用！享受吧。
