Kubernetes k8s带印花棉布，吊舱集装箱罐'；ip外的t ping

我的K8使用印花布。 在我的容器中，我只能ping节点和其他pod。当我尝试访问我的gitserver时，它失败了

    sh-4.1$ ping stash
PING hoffman.domain.local (192.168.33.106) 56(84) bytes of data.
<-- not return ,until ctrl+c

指 我试着去执行

cat << EOF | calicoctl apply -f -
- apiVersion: projectcalico.org/v3
  kind: IPPool
  metadata:
    name: ippool-ext-1
  spec:
    cidr: 192.168.0.0/16
    natOutgoing: true
EOF

根据calicoctl get ippool-o yaml的输出，配置正确：true，无需修改。 k8s集装箱的ip↓

sh-4.1$ ifconfig
eth0      Link encap:Ethernet  HWaddr 9E:AE:6D:96:A4:67  
          inet addr:192.168.100.212  Bcast:0.0.0.0  Mask:255.255.255.255

但在k8s pod容器中，我无法ping我的gitserver。我还只是在节点上运行了一个docker容器，使用相同的映像，它工作正常，git克隆成功。

我的K8S容器ip:eth0 inet addr:192.168.100.212 Bcast:0.0.0.0 Mask:255.255.255这些节点是云中的虚拟机吗？您的pod子网和外部网络可能重叠。尝试将pod cidr更改为例如

10.0.0.0/16

这些节点是真正的主机。在节点上，我可以ping git服务器（192.168.33.106）。来自@Matt的评论帮助我解决了类似问题。
