kubernetes ingress-nginx 0.15.0使用

1 創建相關資源

# kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml

此時ingress-nginx-controller還不能使用，container日誌顯示缺少ingress-nginx服務。

2 創建ingress-nginx服務

# kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/baremetal/service-nodeport.yaml

3 測試

# kubectl get svc  -o wide -n ingress-nginx
