kube-calico bird：Mesh_172_26_178_195：套接字错误：绑定：地址不可用

当节点上的 kube-calico 服务尝试连接主节点时出现问题：Dec 17 12:03:41 a docker[27052]: bird: Mesh_47_105_189_58: Socket error: bind: Address not available Dec 17 12:03:41 a docker[27052]: bird: Mesh_172_26_178_195: Socket error: bind: Address not available

下面是我在 master 上的 etcd 配置（172.26.178.195:2379 是我的私有 IP）：

对此有什么建议吗？

答案1

calico/node 使用公共 IP 相互通信。但阿里云中的节点位于防火墙后面。一些云提供商默认阻止主机之间的流量，例如在 GCE 中必须创建防火墙规则. 您应该创建允许主机之间通信的防火墙规则。

在 calico/node 容器中也可以使用环境变量IP_AUTODETECTION_METHOD指定要使用的接口/网络。
