kubernetes - 印花布/节点未准备好 : BIRD is not ready: BGP not established

Question

我正在运行 Kubernetes 1.13.2，使用 kubeadm 进行设置，并且正在努力启动和运行 calico 3.5。集群运行在 KVM 之上。

设置:

kubeadm init --apiserver-advertise-address=10.255.253.20 --pod-network-cidr=192.168.0.0/16

修改 calico.yaml要包含的文件:

    - name: IP_AUTODETECTION_METHOD
      value: "interface=ens.*"

已申请 rbac.yaml , etcd.yaml , calico.yaml

来自 kubectl describe pods 的输出:

注意:上面的未知地址(10.255.253.14)是 br0下的IP在 KVM 主机上，不太确定它为什么出现。

Answer 1

我得到了解决方案:

ifconfig 的第一个偏好(在我的例子中)它会尝试连接到不是正确 ip 的工作节点。

解决方案:使用以下步骤更改 calico.yaml 文件以将该 ip 覆盖为 etho-ip。

需要开放端口Calico networking (BGP) - TCP 179

 # Specify interface
            - name: IP_AUTODETECTION_METHOD
              value: "interface=eth1"
