Question

我在这里关注指南：

https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/getting-started-guides/fedora/fedora_manual_config.md

设置一个由1个主人和2个小兵组成的Kubernetes集群。完成所有步骤后，当我创建一个pod时，它会被安排到一个minion但仍然处于Pending状态。

当我查看奴才中的Kubelet日志时，我看到了这个错误：

Jan 24 00:46:21 localhost.localdomain kubelet[2356]: E0124 00:46:21.042058 2356 kubelet.go:906] Error syncing pod, skipping: API error (500): Cannot start container fa6cbc76fe336aca5f9a341c8cf71ad4ba3aec83e276e340d0e5de16a0052001: setup networking set gateway to 10.0.1.0 on device eth0 failed with invalid argument

我的主人网络看起来像这样：

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.109.82  netmask 255.255.255.0  broadcast 192.168.109.255
        inet6 fe80::250:56ff:fe0b:bb1  prefixlen 64  scopeid 0x20<link>
        ether 00:50:56:0b:0b:b1  txqueuelen 1000  (Ethernet)

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

在小兵身上，网络看起来像这样：

[root@localhost ~]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.109.83  netmask 255.255.255.0  broadcast 192.168.109.255
        inet6 fe80::250:56ff:fe0b:bb0  prefixlen 64  scopeid 0x20<link>

        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 777356  bytes 65960933 (62.9 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

kbr0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 10.0.1.0  netmask 255.255.255.0  broadcast 10.0.1.255
        ether 00:00:00:00:00:00  txqueuelen 0  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 1  bytes 42 (42.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

有人会对这里可能出现的问题有任何暗示吗？

谢谢！

您链接到指南的顶部说＆＃34;本指南只能让一个小兵工作。多个小兵需要在kubernetes之外完成功能性网络配置。＆＃34;

您是否为群集完成了任何特殊的网络配置（如flannel）？

如果您想使用Fedora，您可能会更好地遵循Fedora + Ansible说明而不是手动说明。

为什么在Kubernetes上将minion上的网关设置为10.0.1.0会失败？
