测试环境需要临摹开发k8s调度环境,搭建本地minikube时,局域网中别的机器无法访问:
1.minikube version: v0.28.1 无法设置type=loadbalancer;
2.type=nodeport只能通过`minikube ip`:${port}实现本机访问。
故需要配置iptable forward
1./proc/sys/net/ipv4/ip_forward=1 开启转发功能
2.docker pull nginx:1.15
3.docker run -d –name ngx nginx:1.15
4.查询ngx服务ip
xurun@star:~$ docker inspect ngx | grep IPAddress
“SecondaryIPAddresses”: null,
“IPAddress”: “172.17.0.2”,
“IPAddress”: “172.17.0.2”,
5.查询本机网卡
