因节点ip无效而导致纤毛虫荚崩溃
因节点ip无效而导致纤毛虫荚崩溃
提问于 2018-12-14 15:15:33
我正在使用kubespray部署一个kubernetes集群。我把网络插头从棉布改为纤毛。
不幸的是，一些纤毛荚被卡在CrashLoopBackOff中。
kubectl --namespace kube-system get pods --selector k8s-app=cilium --sort-by='.status.containerStatuses[0].restartCount' -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
cilium-2gmwm 1/1 Running 0 14m 10.10.3.102 nodemaster1 <none> <none>
cilium-9ccdp 1/1 Running 0 14m 10.10.3.110 node6 <none> <none>
cilium-c9nh6 1/1 Running 0 14m 10.10.3.107 node3 <none> <none>

cilium-f8z2q 1/1 Running 0 14m 10.10.3.105 node1 <none> <none>
cilium-d96cd 0/1 CrashLoopBackOff 7 14m 10.10.3.106 node2 <none> <none>
cilium-jgmcf 0/1 CrashLoopBackOff 7 14m 10.10.3.103 nodemaster2 <none> <none>
cilium-9zqnr 0/1 CrashLoopBackOff 7 14m 10.10.3.108 node4 <none> <none>
cilium-llt9p 0/1 CrashLoopBackOff 7 14m 10.10.3.104 nodemaster3 <none> <none>在检查崩溃荚的日志时，我可以看到以下致命错误消息：
level=fatal msg="The allocation CIDR is different from the previous cilium instance. This error is most likely caused by a temporary network disruption to the kube-apiserver that prevent Cilium from retrieve the node's IPv4/IPv6 allocation range. If you believe the allocation range is supposed to be different you need to clean up all Cilium state with the `cilium cleanup` command on this node. Be aware this will cause network disruption for all existing containers managed by Cilium running on this node and you will have to restart them." error="Unable to allocate internal IPv4 node IP 10.233.71.1: provided IP is not in the valid range. The range of valid IPs is 10.233.70.0/24." subsys=daemon似乎该节点的IP (本例中为10.233.70.0/24. 10.233.71.1)不尊重有效的范围。
我试着修改kubespray的main.yaml文件以改变子网，但是我多次尝试的只是使崩溃的次数上升和下降……
例如，我尝试过这样的运行：
kube_service_addresses: 10.233.0.0/17
kube_pods_subnet: 10.233.128.0/17
kube_network_node_prefix: 18正如你所看到的，它不起作用。如果你有任何想法..。:-)
Thx

我终于在纤毛师的帮助下解决了这个问题！
您必须将clean-cilium-state键从false设置为kubespray文件kubespray/roles/network_plugin/cilium/templates/cilium-config.yml.j2中的true。
在部署之后，您必须恢复此布尔值。为此，执行kubectl edit configmap cilium-config -n kube-system并将键clean-cilium-state从true更改为false。
最后你得杀了纤毛荚。
列出豆荚：kubectl get pods -n kube-system
杀死豆荚：kubectl delete pods cilium-xxx cilium-xxx ...
它现在被列为纤毛虫回购上的问题。
