为什么需要Ingress
当我们使用不同类型的服务来暴露应用的时候会遇到一下问题：
LoadBalancer：当我们在使用LoadBalancer类型的Service暴露服务的时候，一般都需要占用一个公网或者是内网IP地址。使用ingress我们就可以通过一个IP地址暴露多个服务。Ingress会根据客户端输入的不同的域名来确定我们需要转发到哪个服务上面去，这样可以节省公网或内网IP地址，同时也能实现负载均衡效果。
NodePort：这种Kubernetes应用暴露方式会在每个节点服务器上暴露30000~32767之间的端口，我们每个Service都会占用这样的端口最少一个。有没有办法只占用一个端口暴露多个应用呢？答案是可以的。需要用到Ingress。
前期准备
集群准备
我们需要准备一个Kubernetes版本为 1.20 到 1.27 的集群，因为下表是Ingress对集群版本的要求(根据自己的Kubernetes集群版本选择一个ingress-nginx的版本进行安装哦)：
| Ingress-Nginx 版本 | Kubernetes集群版本 |
|---|---|
| v1.8.1 | 1.27, 1.26, 1.25, 1.24 |
| v1.3.1 | 1.24, 1.23, 1.22, 1.21, 1.20 |
因为这两个版本的ingress覆盖了目前绝大多数人用的Kubernetes集群，所以就以这两个版本为例为大家搭建Ingress。更多版本对应详情可产考官方文档：https://github.com/kubernetes/ingress-nginx#changelog
可查看我此次准备的Kubernetes集群版本：
因为我的Kubernetes集群版本为 v1.21.14，所以我此次安装的Ingress吧本为1.3.1。
LoadBalancer准备
因为我们需要为Ingress创建类型为LoadBalancer的服务，所以我们需要提前准备好可用于LoadBalancer的IP地址。如果是云服务提供商的Kubernetes，可咨询云服务提供商客服。如果是自建集群，可产考我写的文章安装MetalLB：https://blog.csdn.net/m0_51510236/article/details/130842122?spm=1001.2014.3001.5501#t36
安装Ingress-Nginx
下载地址
Ingress-nginx的官网地址：https://kubernetes.github.io/ingress-nginx/deploy/，此次提供两个版本的下载地址：
v1.3.1
wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.3.1/deploy/static/provider/cloud/deploy.yaml
v1.8.1
wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.8.1/deploy/static/provider/cloud/deploy.yaml
修改文件
我们不能直接执行这个文件，我们还需要修改一些内容，主要是因为国内无法拉取到 registry.k8s.io，我已经用了一些方法将镜像从国外拉取到国内了，你们可以直接使用
因为yaml文件内容较多，避免影响阅读体验，完整的yaml文件放在了文章的最后，想要完整的修改之后的文件内容的可以拖动到文章的最后哦，
v1.3.1
镜像我已经通过一些手段拉取下来并上传到国内的阿里云镜像仓库当中，你们可以直接使用：
# 需要修改的镜像1

修改ingress服务类型配置
这个步骤可以跳过，需要修改的位置两个文件差不多都在334～335行左右，这里只演示一个：
执行安装
我们直接将deploy.yaml复制到k8s-master当中，如图：
我们直接执行它：
kubectl apply -f deploy.yaml
可以看到资源创建成功：
因为它创建了一个 ingress-nginx 的命名空间，我们直接使用以下命令查看资源是否部署成功：
kubectl get all -o wide -n ingress-nginx
当看到以下内容证明安装成功：
然后我们可以使用以下命令查看本集群已经存在的nginx类型：
kubectl get ingressclass
如下图可以看到目前已经有一个名字为nginx的ingress类型：
部署应用
我们先来暴露一个nginx服务应用(因为dockerhub拉取较慢，所以使用我自己拉取的nginx镜像)：
apiVersion: apps/v1
kind: Deployment
metadata:labels:app: nginx-deployname: nginx-deploy
spec:replicas: 3selector:matchLabels:app: nginx-deploystrategy: {}template:metadata:labels:app: nginx-deployspec:containers:- image: registry.cn-shenzhen.aliyuncs.com/xiaohh-docker/nginx:1.21.6name: nginxports:- containerPort: 80resources: {}
status: {}---apiVersion: v1
kind: Service
metadata:labels:app: nginx-deployname: nginx-svc
spec:ports:- port: 80protocol: TCPtargetPort: 80selector:app: nginx-deploytype: ClusterIP
status:loadBalancer: {}
查看部署结果(kubectl get pod,svc -o wide)：
访问一下验证是否安装成功(curl {IP地址})：
通过ingress-nginx暴露应用
我们之前部署了一个nginx，并暴露了一个类型为 ClusterIP 且名字为 nginx-svc 的服务。接下来我们就要使用ingress-nginx来暴露这个nginx服务。可以具体查看以下yaml配置：
apiVersion: networking.k8s.io/v1
kind: Ingress # 创建一个类型为Ingress的资源
metadata:name: nginx-ingress # 这个资源的名字为 nginx-ingress
spec:ingressClassName: nginx # 使用nginxrules:- host: cloud.yueyang.city # 访问此内容的域名http:paths:- backend:service:name: nginx-svc # 对应nginx的服务名字port:number: 80 # 访问的端口path: / # 匹配规则pathType: Prefix # 匹配类型，这里为前缀匹配
status:loadBalancer: {}
直接执行：
查看创建结果(kubectl get ingress)：
可以看到后面暴露了一个地址，我们将域名解析上去（当然也可以更改你系统的hosts配置文件）：
访问此域名：
好的，ingress就安装完毕了，关注我，下期将部署https应用。
