"Calico CNI - Calico -kube-控制器未能初始化Calico数据存储“错误

Question

我在Kubernetes版本的v3.19.1上运行Calico v1.19.13。该集群使用CentOS Steam 8和RHEL 8操作系统，具有3个主节点和3个节点。

当calico-kube-controller在worker节点上启动时。它在[FATAL][1] main.go 118: Failed to initialize Calico data store错误消息中失败。

我在部署棉布时使用了下面的设置

    # Auto-detect the BGP IP address.
    - name: IP
      value: "autodetect"
    - name: IP_AUTODETECTION_METHOD
      value: "interface=en.*"
    - name: FELIX_IPTABLESBACKEND
      value: "NFT"

启动时的错误消息：

有任何解决此错误消息的提示吗？

谢谢SR

试试这个你的主节点，这是我的工作。

  $ sudo iptables -P INPUT ACCEPT
  $ sudo iptables -P FORWARD ACCEPT
  $ sudo iptables -P FORWARD ACCEPT
  $ sudo iptables -F
