nodePort的缺点

• 一个端口只能一个服务使用，端口需要提前规划
• 只支持4层负载均衡（传输层，只能根据IP和端口进行转发。如LVS、nginx）

Ingress和Ingress Controller

• K8S中一个抽象的资源，给管理员提供一个暴露应用的入口定义方法。
• Ingress Controller是根据Ingress生成具体的路由规则，并对Pod负载均衡器。

暴露Ingress Controller两种方式

• Service端NodePort暴露Ingress Controller（默认使用NodePort）。

  • 基于NodePort访问ingress Controller流程 ： 域名 ——> service NodePort（80:32695/TCP,443:30515/TCP） ——> iptables/ipvs ——> ingress Controller（nginx，基于域名进行分流） ——> pod

• 共享宿主机网络（hostNetwork：True）

  • 基于宿主机网络访问：域名 ——> ingress Controller（nginx，基于域名进行分流） ——> pod

安装 Ingress Controller，基于NodePort访问 1、下载资源

可以去我的资源中下载所需要的yaml文件，也可以直接到文章最后复制已经修改过的yaml文件内容

2、ingress基于NodePort进行访问

[root@k8s-master K8S]# kubectl apply -f deploy.yaml

[root@k8s-master K8S]# kubectl get pod  -n ingress-nginx	#(主要看最下面哪个任务是否起来，上面2个都是临时任务)
NAME                                        READY   STATUS      RESTARTS   AGE
ingress-nginx-admission-create-x5x59        0/1     Completed   0          11m
ingress-nginx-admission-patch-45sm2         0/1     Completed   0          11m
ingress-nginx-controller-6954dc448f-b7xrk   1/1     Running     0          11m

[root@k8s-master K8S]# kubectl get service  -n ingress-nginx	#（80:32695/TCP,443:30515/TCP 这2个端口）        	    
NAME                                         TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE
service/ingress-nginx-controller             NodePort    10.108.193.119           80:32695/TCP,443:30515/TCP   45s
service/ingress-nginx-controller-admission   ClusterIP   10.111.25.108            443/TCP                      45s

[root@k8s-master ~]# kubectl create ingress test --rule=host/path=zhao:80 --dry-run=client -o yaml > jiujiu.yaml		#（可以生成ingress的yaml配置，也可以去K8S官网找ingress的案例，以下实例实在官网找的）
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: web
spec:
  ingressClassName: "nginx"       # 指定nginx控制器
  rules:
  - host: www.huo.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: zhao          # 使用ingress必须先创建service，这个是将zhao这个service端暴露出去
            port:
              number: 80

3、出现ingress内部访问错误

当我执行kubectl apply -f jiujiu.yaml命令时出现了ingress 内部访问错误，错误代码如下：

Error from server (InternalError): error when creating "jiujiu.yaml": Internal error occurred: failed calling webhook "validate.nginx.ingress.kubernetes.io": failed to call webhook: Post "https://ingress-nginx-controller-admission.ingress-nginx.svc:443/networking/v1/ingresses?timeout=10s": x509: certificate has expired or is not yet valid: current time 2022-05-16T06:27:58Z is before 2022-05-17T05:50:15Z

4、解决方案

[root@k8s-master ~]# kubectl get ValidatingWebhookConfiguration	#查找K8S准入控制器
ingress-nginx-admission   1          3h58m

[root@k8s-master ~]# kubectl delete -A ValidatingWebhookConfiguration ingress-nginx-admission	#删除这条准入控制器，在重新执行创建yaml的命令就可以了

[root@k8s-master ~]# kubectl get ingress             
NAME   CLASS   HOSTS            ADDRESS         PORTS   AGE
web    nginx   zz.yanxuan.com   10.107.71.217   80      8m37s

5、查找暴露出的端口信息

[root@k8s-master K8S]# kubectl get service  -n ingress-nginx	#（记录暴露出的32695端口）
NAME                                         TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE
service/ingress-nginx-controller             NodePort    10.108.193.119           80:32695/TCP,443:30515/TCP   45s
service/ingress-nginx-controller-admission   ClusterIP   10.111.25.108            443/TCP                      45s

[root@k8s-master ~]# kubectl get pod -n ingress-nginx -o wide	# 查看ingress-nginx在哪个node节点上。在哪个节点上就要用哪个节点的ip做映射，否则会失败。
  ME                                       READY   STATUS      RESTARTS   AGE   IP               NODE        NOMINATED NODE   READINESS GATES
ingress-nginx-admission-create-5hvx5       0/1     Completed   0          67m   10.244.36.69     k8s-node1              
ingress-nginx-admission-patch-k7v7f        0/1     Completed   1          67m   10.244.169.187   k8s-node2              
ingress-nginx-controller-64b844d68-gm8g9   1/1     Running     0          67m   10.244.36.71     k8s-node1              

在C:WindowsSystem32driversetchosts中做映射：
192.168.153.181 www.huo.com #153.181是node1的ip地址

6、 在浏览器中访问www.huo.com:32695

ingress基于宿主机网络访问 1、新增hostName字段

2、执行容器重建命令

[root@k8s-master K8S]# kubectl apply -f deploy.yaml

[root@k8s-master K8S]# kubectl get pod -n ingress -o wide
NAME                                        READY   STATUS      RESTARTS   AGE   IP                NODE        NOMINATED NODE   READINESS GATES
ingress-nginx-admission-create-5hvx5        0/1     Completed   0          18h   10.244.36.69      k8s-node1              
ingress-nginx-admission-patch-k7v7f         0/1     Completed   1          18h   10.244.169.187    k8s-node2              
ingress-nginx-controller-85b88695bf-6qwhm   1/1     Running     0          48s   192.168.153.181   k8s-node1              

3、浏览器访问www.huo.com可以直接访问到nginx

ingress 修改限制请求大小案例

• ingress-nginx会配置一些默认的参数，但是有些参数无法满足日常需求，就需要更改参数设置或者自定义参数。

修改限制请求的大小，默认是1M，更改为8M

[root@k8s-master ~]# vim jiujiu.yaml              
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: web
  annotations:		# 新增修改时添加注解
    nginx.ingress.kubernetes.io/proxy-body-size: "8m"
spec:
  ingressClassName: "nginx"       # 指定nginx控制器
  rules:
  - host: www.huo.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: zhao            # 使用ingress必须先创建service，这个是将zhao这个service端暴露出去
            port:
              number: 80

[root@k8s-master ~]# kubectl get pod -n ingress-nginx
NAME                                        READY   STATUS      RESTARTS   AGE
ingress-nginx-admission-create-5ggvw        0/1     Completed   0          15m
ingress-nginx-admission-patch-fl72k         0/1     Completed   0          15m
ingress-nginx-controller-85b88695bf-g4g9v   1/1     Running     0          15m

[root@k8s-master ~]# kubectl exec -it -n ingress-nginx ingress-nginx-controller-85b88695bf-g4g9v -- bash

ingress 跳转JD案例

[root@k8s-master ~]# vim jiujiu.yaml 
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: web
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: "https://jd.com"
    nginx.ingress.kubernetes.io/proxy-body-size: "8m"
spec:
  ingressClassName: "nginx"       # 指定nginx控制器
  rules:
  - host: www.huo.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: zhao            # 使用ingress必须先创建service，这个是将zhao这个service端暴露出去
            port:
              number: 80

浏览器直接访问www.huo.com就能跳转到JD 自定义 ingress 1、将123.txt的跳转到百度 2、将888.gif的跳转到京东

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: web
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: "8m"
    nginx.ingress.kubernetes.io/server-snippet: |
      if ($uri ~* "123.txt") {			# $uri自定义
        rewrite (.+) https://www.baidu.com;
      }
      if ($uri ~* "888.gif") {
        rewrite (.+) https://www.jd.com;
      }
spec:
  ingressClassName: "nginx"       # 指定nginx控制器
  rules:
  - host: www.huo.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: zhao            # 使用ingress必须先创建service，这个是将zhao这个service端暴露出去
            port:
              number: 80

在浏览器输入www.huo.com/123.txt，会跳转到百度 在浏览器输入www.huo.com/888.gif，会跳转到京东
