k8s calico网络排错2
解决了跨node的pod连通性,接下来面临新问题,首先是nodeport只对pod所在node能够访问。http://dockone.io/question/1504参考上面链接,执行sudo iptables -P FORWARD ACCEPT初步解决该问题,hadoop001的还是不行报错如下:Chain KUBE-SERVICES (2 references)target...
解决了跨node的pod连通性,接下来面临新问题,首先是nodeport只对pod所在node能够访问。
http://dockone.io/question/1504
参考上面链接,执行sudo iptables -P FORWARD ACCEPT初步解决该问题,hadoop001的还是不行
报错如下:
Chain KUBE-SERVICES (2 references)
target prot opt source destination
REJECT tcp -- anywhere anywhere /* pezy/hbase-hmaster:master-web has no endpoints */ ADDRTYPE match dst-type LOCAL tcp dpt:32098 reject-with icmp-port-unreachable

后发现hadoop001的docker镜像,外部无法访问,包括私有仓库,重启仓库。
发现ip转发没有开。
[root@hadoop001 ~]# docker run -d -p 5000:5000 -v /dlw_registry:/var/lib/registry registry:2.6.0
WARNING: IPv4 forwarding is disabled. Networking will not work.

解决办法:
# vi /etc/sysctl.conf
或者
# vi /usr/lib/sysctl.d/00-system.conf
添加如下代码:
net.ipv4.ip_forward=1
重启network服务
# systemctl restart network
查看是否修改成功
# sysctl net.ipv4.ip_forward
如果返回为“net.ipv4.ip_forward = 1”则表示成功了
修改后,仓库可以访问,docker可以外部访问。
