一、ingress

二、ingress安装

Ingress-Nginx github 地址：https://github.com/kubernetes/ingress-nginx

Ingress-Nginx 官方网站：https://kubernetes.github.io/ingress-nginx/

部署 Ingress-Nginx

kubectl apply -f mandatory.yaml
kubectl apply -f service-nodeport.yaml

先科学镜像下载

上传镜像到master节点

传给其它机器

所有节点，分别解压导入

三、Ingress HTTP 代理访问

deployment、Service、Ingress Yaml 文件

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
 name: nginx-dm
spec:
 replicas: 2
 template:
  metadata:
   labels:
    name: nginx
  spec:
   containers:
    - name: nginx
      image: wangyanglinux/myapp:v1
      imagePullPolicy: IfNotPresent
      ports:
       - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
 name: nginx-svc
spec:
 ports:
  - port: 80
    targetPort: 80
    protocol: TCP
 selector:
  name: nginx

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
 name: nginx-test
spec:
 rules:
  - host: www1.atguigu.com
    http:
     paths:
     - path: /
       backend:
        serviceName: nginx-svc
        servicePort: 80

本地增加域名解析

删除之前测试的svc

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
 name: deployment1
spec:
 replicas: 2
 template:
  metadata:
   labels:
    name: nginx
  spec:
   containers:
    - name: nginx
      image: wangyanglinux/myapp:v1
      imagePullPolicy: IfNotPresent
      ports:
       - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
 name: svc-1
spec:
 ports:
  - port: 80
    targetPort: 80
    protocol: TCP
 selector:
  name: nginx

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
 name: ingress1
spec:
 rules:
  - host: www1.atguigu.com
    http:
     paths:
     - path: /
       backend:
        serviceName: svc-1
        servicePort: 80
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
 name: ingress2
spec:
 rules:
  - host: www2.atguigu.com
    http:
     paths:
     - path: /
       backend:
        serviceName: svc-2
        servicePort: 80

四、Ingress HTTPS 代理访问 1.创建证书，以及 cert 存储方式

openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj
"/CN=nginxsvc/O=nginxsvc"
kubectl create secret tls tls-secret --key tls.key --cert tls.crt

2.deployment、Service、Ingress Yaml 文件

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
 name: nginx-test
spec:
 tls:
  - hosts:
   - foo.bar.com
   secretName: tls-secret
 rules:
  - host: foo.bar.com
    http:
     paths:
     - path: /
       backend:
        serviceName: nginx-svc
        servicePort: 80

五、Nginx 进行 BasicAuth

yum -y install httpd
htpasswd -c auth foo
kubectl create secret generic basic-auth --from-file=auth

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
 name: ingress-with-auth
 annotations:
  nginx.ingress.kubernetes.io/auth-type: basic
  nginx.ingress.kubernetes.io/auth-secret: basic-auth
  nginx.ingress.kubernetes.io/auth-realm: 'Authentication Required - foo'
spec:
 rules:
 - host: foo2.bar.com
  http:
   paths:
   - path: /
     backend:
      serviceName: nginx-svc
      servicePort: 80

六、Nginx 进行重写

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
 name: nginx-test
 annotations:
  nginx.ingress.kubernetes.io/rewrite-target: http://foo.bar.com:31795/hostname.html
spec:
 rules:
 - host: foo10.bar.com
   http:
    paths:
    - path: /
      backend:
       serviceName: nginx-svc
       servicePort: 80
