具体安装步骤与k8s-v1.28.0一致：https://qq829.cn/book/books/k8s/page/k8s-v1280

已知问题（不能开低于1024端口），其中nginx-ingress处理方法相同

# coredns提示 listen tcp :53: bind: permission denied

kubectl edit deploy coredns -n kube-system

    allowPrivilegeEscalation: true
    capabilities:
      add:
      - NET_BIND_SERVICE
      drop:
      - ALL
    readOnlyRootFilesystem: true

已知问题，让pod在每一台机器执行，而不管节点是否有污点

# 加在与volumes同级
      tolerations:
        - effect: NoSchedule
          operator: Exists
        - key: CriticalAddonsOnly
          operator: Exists
        - effect: NoExecute
          operator: Exists
