Kubernetes 集群安装 ingress-nginx

先将相关的虚拟机进行快照保存下来
virsh snapshot-create-as gongdear-kubernetes-master k8smaster-k8s_dns_done

virsh snapshot-create-as gongdear-kubernetes-node2 k8snode2-k8s_dns_done
virsh snapshot-create-as gongdear-kubernetes-node3 k8snode3-k8s_dns_done

在 master 节点上创建如下配置文件
default-backend.yaml

nginx-ingress-controller.yaml

args:
- /nginx-ingress-controller
- --default-backend-service=$(POD_NAMESPACE)/default-http-backend
- --apiserver-host=http://192.168.1.120:8080
apiserver-host=http://192.168.1.120:8080 需要配置成自己的 apiserver 地址

然后就是自己的业务配置
[root@kubernetesmaster ingress]# cat dashboard-ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: dashboard-ingress
namespace: kube-system
spec:
rules:

• host: kubernetesnode2
  http:
  paths:
  • path: /
    backend:
    serviceName: kubernetes-dashboard
    servicePort: 80

kubectl create -f 上面的配置
查看配置结果


此时浏览器访问 http://kubernetesnode2 就可以打开 dashboard 页面
