部署kubernetes/ingress-nginx(踩坑)

nginx-ingress-controller:0.25.0有问题，所以这里采用nginx-ingress-controller:0.30.0

[root@k8s-master ~]# wget ~]# cat mandatory.yaml | grep imageimage: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.30.0

所有节点下载quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.30.0[root@k8s-master ~]# docker pull quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.30.0

[root@k8s-master ~]# kubectl apply -f mandatory.yaml
