Kubernetes 1.4和編織網：網絡不能正常工作

Question

我用Kubeadm來引導集羣，並添加編織網與

kubectl apply -f https://git.io/weave-kube

，我所擁有的一切運行，但我不能「請參閱「集羣內任何分配的IP。

所以：

[centos@atomic01 ~]$ kubectl get pods --all-namespaces -o wide
NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE default hello-2533203682-b5usp 1/1 Running 0 13m 10.42.0.0 atomic03 default test-701078429-ely8s 1/1 Running 1 3h 10.40.0.1 atomic02 kube-system dummy-2088944543-6i81l 1/1 Running 0 5h 192.168.150.150 atomic01 kube-system etcd-atomic01 1/1 Running 0 5h 192.168.150.150 atomic01 kube-system kube-apiserver-atomic01 1/1 Running 0 5h 192.168.150.150 atomic01 kube-system kube-controller-manager-atomic01 1/1 Running 0 5h 192.168.150.150 atomic01 kube-system kube-discovery-982812725-c1kkw 1/1 Running 0 5h 192.168.150.150 atomic01 kube-system kube-dns-2247936740-nrszw 3/3 Running 2 5h 10.32.0.2 atomic01 kube-system kube-proxy-amd64-0y8ik 1/1 Running 1 5h 192.168.150.152 atomic03 kube-system kube-proxy-amd64-57y4o 1/1 Running 0 5h 192.168.150.150 atomic01 kube-system kube-proxy-amd64-mjpik 1/1 Running 1 5h 192.168.150.151 atomic02 kube-system kube-proxy-amd64-sh3ej 1/1 Running 1 5h 192.168.150.153 atomic04 kube-system kube-scheduler-atomic01 1/1 Running 0 5h 192.168.150.150 atomic01 kube-system kubernetes-dashboard-3095304083-xwuw8 1/1 Running 1 2h 10.38.0.0 atomic04 kube-system weave-net-edur9 2/2 Running 0 1m 192.168.150.151 atomic02 kube-system weave-net-l9xp3 2/2 Running 0 1m 192.168.150.150 atomic01 kube-system weave-net-sjpui 2/2 Running 0 1m 192.168.150.153 atomic04 kube-system weave-net-xu7j5 2/2 Running 0 1m 192.168.150.152 atomic03

我應該能夠ping其他節點，但

[centos@atomic01 ~]$ kubectl exec test-701078429-ely8s -- ping 10.42.0.0 PING 10.42.0.0 (10.42.0.0) 56(84) bytes of data. From 10.40.0.1 icmp_seq=1 Destination Host Unreachable From 10.40.0.1 icmp_seq=2 Destination Host Unreachable From 10.40.0.1 icmp_seq=3 Destination Host Unreachable

當然，這個工程：

[centos@atomic01 ~]$ kubectl exec test-701078429-ely8s -- ping 192.168.150.150 PING 192.168.150.150 (192.168.150.150) 56(84) bytes of data. 64 bytes from 192.168.150.150: icmp_seq=1 ttl=63 time=0.484 ms 64 bytes from 192.168.150.150: icmp_seq=2 ttl=63 time=0.448 ms

我已經用完了想法，任何線索要測試或尋找的東西將不勝感激。 [在Centos 7 Atomic VM上運行]

Answer 1

嗯，是否有任何測試或hello Pods公開任何端口？您可以從測試窗口訪問hello窗格上的端口嗎？

通常，我不認爲ping應該工作（除非你有一個處理icmp請求的Pod），所以我其實不認爲這裏有什麼問題。

爲了簡單起見，只需運行一個顯示端口爲80的端口（最好來自部署），設置爲containerPort: 80，並且您應該能夠成功地控制該Pod IP。還可以考慮使用穩定的IP來提供服務，以平衡對匹配Pod的請求，因爲Pod可能會來來去去。

希望它有幫助！
