参考官网https://kubernetes.github.io/ingress-nginx/

部署pod：nginx-ingress-controller/nginx-default-backend

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

配置修改：

1. 取消转发body限制：

kind: ConfigMap

apiVersion: v1

metadata:

  name: nginx-configuration

  namespace: ingress-nginx

  labels:

    app.kubernetes.io/name: ingress-nginx

    app.kubernetes.io/part-of: ingress-nginx

data:

  proxy-body-size: "0"

k8s裸机部署bare-metal(nodeport方式):

部署service

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

配置修改：

apiVersion: v1

kind: Service

metadata:

  name: ingress-nginx

  namespace: ingress-nginx

  labels:

    app.kubernetes.io/name: ingress-nginx

    app.kubernetes.io/part-of: ingress-nginx

spec:

  ports:

  - name: http

    port: 8083

    targetPort: 80

    protocol: TCP

  - name: https

    port: 8084

    targetPort: 443

    protocol: TCP

  selector:

    app.kubernetes.io/name: ingress-nginx

    app.kubernetes.io/part-of: ingress-nginx

  externalIPs:

  - "{portal_host}"

Note：保证镜像能正常下载

部署Ingress(前提：game2048-pod/service已经部署完毕)

apiVersion: extensions/v1beta1

kind: Ingress

metadata:

  name: game-ingress

  namespace: default

  annotations:

    nginx.ingress.kubernetes.io/rewrite-target: /

    nginx.ingress.kubernetes.io/ssl-redirect: "false"

spec:

  rules:

  - http:

      paths:

      - path: /game

        backend:

          serviceName: game2048

          servicePort: 7090

验证：

curl  http://external_ip:port/game

response正常
