k8s部署ingress-nginx

ingress-nginx的部署方式有多种，本文介绍nodeport方式和hostnetwork方式：

一、nodeport方式

1、下载mandatory.yaml文件：https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/mandatory.yaml

然后修改文件中的镜像：registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller:0.25.1

2、编辑service-nodeport.yaml(nodeport方式需要额外使用这个文件)

apiVersion: v1
kind: Service

  name: ingress-nginx
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx

  ports:
    - name: http
      port: 80
      targetPort: 80
      protocol: TCP
      nodePort: 32080  #http
    - name: https
      port: 443
      targetPort: 443
      protocol: TCP
      nodePort: 32443  #https
