Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用

這篇具有很好參考價(jià)值的文章主要介紹了Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用。希望對(duì)大家有所幫助。如果存在錯(cuò)誤或未考慮完全的地方，請(qǐng)大家不吝賜教，您也可以點(diǎn)擊"舉報(bào)違法"按鈕提交疑問(wèn)。

為什么需要Ingress

當(dāng)我們使用不同類(lèi)型的服務(wù)來(lái)暴露應(yīng)用的時(shí)候會(huì)遇到一下問(wèn)題：

LoadBalancer：當(dāng)我們?cè)谑褂肔oadBalancer類(lèi)型的Service暴露服務(wù)的時(shí)候，一般都需要占用一個(gè)公網(wǎng)或者是內(nèi)網(wǎng)IP地址。使用ingress我們就可以通過(guò)一個(gè)IP地址暴露多個(gè)服務(wù)。Ingress會(huì)根據(jù)客戶(hù)端輸入的不同的域名來(lái)確定我們需要轉(zhuǎn)發(fā)到哪個(gè)服務(wù)上面去，這樣可以節(jié)省公網(wǎng)或內(nèi)網(wǎng)IP地址，同時(shí)也能實(shí)現(xiàn)負(fù)載均衡效果。

NodePort：這種Kubernetes應(yīng)用暴露方式會(huì)在每個(gè)節(jié)點(diǎn)服務(wù)器上暴露30000~32767之間的端口，我們每個(gè)Service都會(huì)占用這樣的端口最少一個(gè)。有沒(méi)有辦法只占用一個(gè)端口暴露多個(gè)應(yīng)用呢？答案是可以的。需要用到Ingress。

前期準(zhǔn)備

集群準(zhǔn)備

我們需要準(zhǔn)備一個(gè)Kubernetes版本為 1.20 到 1.27 的集群，因?yàn)橄卤硎荌ngress對(duì)集群版本的要求(根據(jù)自己的Kubernetes集群版本選擇一個(gè)ingress-nginx的版本進(jìn)行安裝哦)：

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?yàn)檫@兩個(gè)版本的ingress覆蓋了目前絕大多數(shù)人用的Kubernetes集群，所以就以這兩個(gè)版本為例為大家搭建Ingress。更多版本對(duì)應(yīng)詳情可產(chǎn)考官方文檔：https://github.com/kubernetes/ingress-nginx#changelog
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

可查看我此次準(zhǔn)備的Kubernetes集群版本：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

因?yàn)槲业腒ubernetes集群版本為 v1.21.14，所以我此次安裝的Ingress吧本為1.3.1。

LoadBalancer準(zhǔn)備

因?yàn)槲覀冃枰獮镮ngress創(chuàng)建類(lèi)型為L(zhǎng)oadBalancer的服務(wù)，所以我們需要提前準(zhǔn)備好可用于LoadBalancer的IP地址。如果是云服務(wù)提供商的Kubernetes，可咨詢(xún)?cè)品?wù)提供商客服。如果是自建集群，可產(chǎn)考我寫(xiě)的文章安裝MetalLB：https://blog.csdn.net/m0_51510236/article/details/130842122?spm=1001.2014.3001.5501#t36

安裝Ingress-Nginx

下載地址

Ingress-nginx的官網(wǎng)地址：https://kubernetes.github.io/ingress-nginx/deploy/，此次提供兩個(gè)版本的下載地址：

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

我們不能直接執(zhí)行這個(gè)文件，我們還需要修改一些內(nèi)容，主要是因?yàn)閲?guó)內(nèi)無(wú)法拉取到 registry.k8s.io，我已經(jīng)用了一些方法將鏡像從國(guó)外拉取到國(guó)內(nèi)了，你們可以直接使用

因?yàn)閥aml文件內(nèi)容較多，避免影響閱讀體驗(yàn)，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內(nèi)容的可以拖動(dòng)到文章的最后哦，

v1.3.1

鏡像我已經(jīng)通過(guò)一些手段拉取下來(lái)并上傳到國(guó)內(nèi)的阿里云鏡像倉(cāng)庫(kù)當(dāng)中，你們可以直接使用：

修改ingress服務(wù)類(lèi)型配置

這個(gè)步驟可以跳過(guò)，需要修改的位置兩個(gè)文件差不多都在334～335行左右，這里只演示一個(gè)：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

執(zhí)行安裝

我們直接將deploy.yaml復(fù)制到k8s-master當(dāng)中，如圖：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

我們直接執(zhí)行它：

kubectl apply -f deploy.yaml

可以看到資源創(chuàng)建成功：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

因?yàn)樗鼊?chuàng)建了一個(gè) ingress-nginx 的命名空間，我們直接使用以下命令查看資源是否部署成功：

kubectl get all -o wide -n ingress-nginx

當(dāng)看到以下內(nèi)容證明安裝成功：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

然后我們可以使用以下命令查看本集群已經(jīng)存在的nginx類(lèi)型：

kubectl get ingressclass

如下圖可以看到目前已經(jīng)有一個(gè)名字為nginx的ingress類(lèi)型：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

部署應(yīng)用

我們先來(lái)暴露一個(gè)nginx服務(wù)應(yīng)用(因?yàn)閐ockerhub拉取較慢，所以使用我自己拉取的nginx鏡像)：

apiVersion: apps/v1
kind: Deployment

        name: nginx
        ports:
        - containerPort: 80
        resources: {}

    protocol: TCP
    targetPort: 80

    app: nginx-deploy
  type: ClusterIP

查看部署結(jié)果(kubectl get pod,svc -o wide)：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

訪問(wèn)一下驗(yàn)證是否安裝成功(curl {IP地址})：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

通過(guò)ingress-nginx暴露應(yīng)用

我們之前部署了一個(gè)nginx，并暴露了一個(gè)類(lèi)型為 ClusterIP 且名字為 nginx-svc 的服務(wù)。接下來(lái)我們就要使用ingress-nginx來(lái)暴露這個(gè)nginx服務(wù)。可以具體查看以下yaml配置：

apiVersion: networking.k8s.io/v1
kind: Ingress # 創(chuàng)建一個(gè)類(lèi)型為Ingress的資源
metadata:
  name: nginx-ingress # 這個(gè)資源的名字為 nginx-ingress
spec:
  ingressClassName: nginx # 使用nginx
  rules:
  - host: cloud.yueyang.city # 訪問(wèn)此內(nèi)容的域名
    http:
      paths:
      - backend:
          service:
            name: nginx-svc # 對(duì)應(yīng)nginx的服務(wù)名字
            port:
              number: 80 # 訪問(wèn)的端口
        path: / # 匹配規(guī)則
        pathType: Prefix # 匹配類(lèi)型，這里為前綴匹配
status:
  loadBalancer: {}

直接執(zhí)行：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

查看創(chuàng)建結(jié)果(kubectl get ingress)：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

可以看到后面暴露了一個(gè)地址，我們將域名解析上去（當(dāng)然也可以更改你系統(tǒng)的hosts配置文件）：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

訪問(wèn)此域名：
Kubernetes(k8s)當(dāng)中安裝并使用ingress暴露應(yīng)用,軟件安裝,kubernetes,容器,云原生

好的，ingress就安裝完畢了，關(guān)注我，下期將部署https應(yīng)用。
