我已按照最新的说明(2015年5月7日更新)在ebu和flanneld中使用Ubuntu **设置群集。但是我在网络上遇到了麻烦......它似乎处于某种破碎状态。
**注意:我更新了配置脚本,使其安装了0.16.2。此外,kubectl get minions
无法启动,但在sudo service kube-controller-manager restart
出现之后。
这是我的设置:
| ServerName | Public IP | Private IP |
------------------------------------------
| KubeMaster | 107.x.x.32 | 10.x.x.54 |
| KubeNode1 | 104.x.x.49 | 10.x.x.55 |
| KubeNode2 | 198.x.x.39 | 10.x.x.241 |
| KubeNode3 | 104.x.x.52 | 10.x.x.190 |
| MongoDev1 | 162.x.x.132 | 10.x.x.59 |
| MongoDev2 | 104.x.x.103 | 10.x.x.60 |
从任何机器我可以ping任何其他机器......当我创建pod和服务时,我开始遇到问题。
POD IP CONTAINER(S) IMAGE(S) HOST LABELS STATUS CREATED
auth-dev-ctl-6xah8 172.16.37.7 sis-auth leportlabs/sisauth:latestdev 104.x.x.52/104.x.x.52 environment=dev,name=sis-auth Running 3 hours
所以这个pod已经在KubeNode3
上进行了调整...如果我尝试从除了KubeNode3以外的任何机器ping它,我会收到Destination Net Unreachable
错误。 E.g。
# ping 172.16.37.7
PING 172.16.37.7 (172.16.37.7) 56(84) bytes of data.
From 129.250.204.117 icmp_seq=1 Destination Net Unreachable
我可以在所有四个人上拨打etcdctl get /coreos.com/network/config
并返回{"Network":"172.16.0.0/16"}
。
我不确定从哪里看。任何人都可以帮助我吗?

答案 0 :(得分:0)
所以我注意到法兰绒配置(/run/flannel/subnet.env
)与docker的启动不同(不知道它们是如何不同步的)。
# ps -ef | grep docker
root 19663 1 0 May07 ? 00:09:20 /usr/bin/docker -d -H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock --bip=172.16.85.1/24 --mtu=1472
# cat /run/flannel/subnet.env
FLANNEL_SUBNET=172.16.60.1/24
FLANNEL_MTU=1472
FLANNEL_IPMASQ=false
请注意,泊坞窗--bip=172.16.85.1/24
与法兰绒子网FLANNEL_SUBNET=172.16.60.1/24
不同。
很自然地,我改变了/etc/default/docker
以反映新值。
DOCKER_OPTS="-H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock --bip=172.16.60.1/24 --mtu=1472"
但现在sudo service docker restart
没有错误...所以看/var/log/upstart/docker.log
我可以看到以下内容
FATA[0000] Shutting down daemon due to errors: Bridge ip (172.16.85.1) does not match existing bridge configuration 172.16.60.1
所以拼图的最后一块是删除旧桥并重新启动docker ......
# sudo brctl delbr docker0
# sudo service docker start
如果sudo brctl delbr docker0
返回bridge docker0 is still up; can't delete it
运行ifconfig docker0 down
,请重试。
答案 1 :(得分:-1)
请试试这个:
ip link del docker0
systemctl restart flanneld
