1、故障现象： kubenetes安装calico发现其中一个处于Running，但READY列却显示不正常，状态如下图所示：  2、寻找原因 进入到出现故障 pod，查看router id值发现绑定地址异常，并非宿主机的IP地址 ``` [root@master01 ~]# kubectl exec -ti calico-node-j4f5m -n kube-system -- bash [root@k8s-master1 /]# cat /etc/calico/confd/config/bird.cfg ```  3、解决方法 （1）、calico.yaml 文件添加以下两行，网卡使用ifconfig查看宿主机的网卡名称，我的宿主机的网卡名称是 ens33 ``` [root@master01 ~]# ifconfig docker0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 inet 172.17.0.1 netmask 255.255.0.0 broadcast 172.17.255.255 ether 02:42:7d:18:01:ae txqueuelen 0 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.31.73 netmask 255.255.255.0 broadcast 192.168.31.255 inet6 fe80::c8f3:b547:a509:d990 prefixlen 64 scopeid 0x20 ether 00:0c:29:d8:0c:67 txqueuelen 1000 (Ethernet) RX packets 4740537 bytes 1428558903 (1.3 GiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 4178151 bytes 627478129 (598.4 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ``` 这里直接配置通配符 ：value: "interface=ens.*" ``` [root@master01 ~]# vi calico.yaml # Cluster type to identify the deployment type - name: CLUSTER_TYPE value: "k8s,bgp" #新增两行配置 - name: IP_AUTODETECTION_METHOD value: "interface=ens.*" # Auto-detect the BGP IP address. - name: IP value: "autodetect" # Enable IPIP - name: CALICO_IPV4POOL_IPIP value: "Always" ``` （2）、重新应用 ``` [root@master01 ~]# rm -rf /var/lib/cni [root@master01 ~]# kubectl apply -f calico.yaml [root@master01 ~]# kubectl get pods -n kube-system NAME READY STATUS RESTARTS AGE calico-kube-controllers-97769f7c7-8jzg7 1/1 Running 0 72m calico-node-qfwsp 1/1 Running 0 104s calico-node-qtn9z 1/1 Running 0 2m3s calico-node-xdswl 1/1 Running 0 2m22s ``` 4、问题解决
