简介： 云原生|kubernetes|ingress-nginx插件部署（kubernetes-1.23和最新版controller-1.6.4）

前言：

ingress是kubernetes内的一个重要功能插件，这个使得服务治理成为一个可能，当然，结合微服务更为妥当了。

不管是什么插件，还是服务，第一步当然是要能顺利的部署到系统当中，这样，才会有后续的使用可能，否则一切无从谈起，对吧。

而kubernetes的版本众多，因此，它的插件版本也是非常多得，而本文将就kubernetes-1.23集群内部署ingress-nginx做一个详细的描述，并指出它（ingress-nginx）和旧版本的不同

一，

部署方法简介

按照部署手法来说，插件一般是使用helm安装并管理的，其次是使用yaml清单文件，但很明显，yaml清单文件的方式更为灵活，能够做一些简单的定制，从可定制性来说，无疑yaml清单是更好的。

本文将使用yaml清单文件的形式部署

按照官方的说法，yaml清单文件的部署效果是和使用helm部署基本一致的（好像说是根据helm生成的）。

二，

ingress-nginx和kubernetes的版本对应关系：

GitHub - kubernetes/ingress-nginx at controller-v1.6.4

Supported Versions table

Supported versions for the ingress-nginx project mean that we have completed E2E tests, and they are passing for the versions listed. Ingress-Nginx versions may work on older versions but the project does not make that guarantee.

（只是一个大概的版本对应表，以下内容是确定的）

Ingress-NGINX version k8s supported version Alpine Version Nginx Version
v1.6.4 1.26, 1.25, 1.24, 1.23 3.17.0 1.21.6
v1.5.1 1.25, 1.24, 1.23 3.16.2 1.21.6
v1.4.0 1.25, 1.24, 1.23, 1.22 3.16.2 1.19.10†
v1.3.1 1.24, 1.23, 1.22, 1.21, 1.20 3.16.2 1.19.10†
v1.3.0 1.24, 1.23, 1.22, 1.21, 1.20 3.16.0 1.19.10†
v1.2.1 1.23, 1.22, 1.21, 1.20, 1.19 3.14.6 1.19.10†
v1.1.3 1.23, 1.22, 1.21, 1.20, 1.19 3.14.4 1.19.10†
v1.1.2 1.23, 1.22, 1.21, 1.20, 1.19 3.14.2 1.19.9†
v1.1.1 1.23, 1.22, 1.21, 1.20, 1.19 3.14.2 1.19.9†
v1.1.0 1.22, 1.21, 1.20, 1.19 3.14.2 1.19.9†
v1.0.5 1.22, 1.21, 1.20, 1.19 3.14.2 1.19.9†
v1.0.4 1.22, 1.21, 1.20, 1.19 3.14.2 1.19.9†
v1.0.3 1.22, 1.21, 1.20, 1.19 3.14.2 1.19.9†
v1.0.2 1.22, 1.21, 1.20, 1.19 3.14.2 1.19.9†
v1.0.1 1.22, 1.21, 1.20, 1.19 3.14.2 1.19.9†
v1.0.0 1.22, 1.21, 1.20, 1.19 3.13.5 1.20.1

根据以上表，可以确定 kubernetes-1.23-1.26都可以使用ingress-nginx-1.6.4

三，

ingress-nginx的yaml清单文件下载地址（其它版本只需要修改v后面的数字即可）：

https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.0.4/deploy/static/provider/cloud/deploy.yaml（这个是示例）

https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.6.4/deploy/static/provider/cloud/deploy.yaml（本文使用的是这个）

 

OK，不谈是安装哪个版本的ingress-nginx，所有的版本的yaml文件都需要一个本土化修改

这里说的本土化和Java开发的时候说的国际化其实挺类似的，主要原因是国内的墙的问题，造成很多镜像无法下载，需要修改成国内可以下载的同一镜像，

例如（上面下载的文件里包含的镜像），

registry.k8s.io/ingress-nginx/kube-webhook-certgen:v20220916-gd32f8c343@sha256:39c5b2e3310dc4264d638ad28d9d1d96c4cbb2b2dcfb52368fe4e3c63f61e10f

修改为：

dyrnq/kube-webhook-certgen:v20220916-gd32f8c343

registry.k8s.io/ingress-nginx/controller:v1.6.4@sha256:15be4666c53052484dd2992efacf2f50ea77a78ae8aa21ccd91af6baaa7ea22f

修改为：

registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller:v1.6.4

ingress-nginx只涉及以上两个镜像

其次是网络的修改，这里要说明一下，ingress-nginx和网络模型是解耦的，也就是说，不需要关心网络模型是IPVS，还是iptables，也不需要关心是flannel还是calico或者是其它的网络插件，主要是修改ingress的对外服务（service）为NodePort，如果有必要，将port固定即可。

apiVersion: v1
kind: Service
metadata:
  labels:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
    app.kubernetes.io/version: 1.6.4
  name: ingress-nginx-controller
  namespace: ingress-nginx
spec:
  externalTrafficPolicy: Local
  ipFamilies:
  - IPv4
  ipFamilyPolicy: SingleStack
  ports:
  - appProtocol: http
    name: http
    port: 80
    protocol: TCP
    targetPort: http
  - appProtocol: https
    name: https
    port: 443
    protocol: TCP
    targetPort: https
  selector:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/name: ingress-nginx
  type: NodePort

下面附上完整的修改后的部署yaml清单文件（以上所说修改已经完成，port固定为31080和31443）：

四，

与旧版的ingress-nginx的一些不同点

云原生|kubernetes|ingress-nginx插件部署以及简单的应用（修订版---适用于kubernetes-1.18-1.21）_安装ingress插件_晚风_END的博客-CSDN博客

这个是1.18集群使用的，主要的不同点集中在ingress资源的api version和一些定义方面的细小差异

1，apiVersion: networking.k8s.io/v1（新版）

apiVersion: extensions/v1beta1（旧版）

2，新版取消了注解，也就是annotations（元数据这不用注解），统一使用ingressClassName（在spec模块使用）

3，ingress直接绑定的是ingress的服务，而旧版绑定的是节点ip：

[root@k8s-master ~]# kubectl get ing -n dev
NAME           CLASS   HOSTS                            ADDRESS          PORTS   AGE
ingress-http   nginx   nginx.test.com,tomcat.test.com   10.109.115.193   80      16h
[root@k8s-master ~]# kubectl get svc -n ingress-nginx 
NAME                                 TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE
ingress-nginx-controller             NodePort    10.109.115.193   <none>        80:31680/TCP,443:31111/TCP   4h47m
ingress-nginx-controller-admission   ClusterIP   10.110.7.6       <none>        443/TCP                      4h47m

4，

新版新增pathType，旧版是使用注解

附注：

有3种支持的path类型：

ImplementationSpecific：对于这种path类型，匹配取决于IngressClass。可以将其视为一个单独的pathType或者将其认为和Prefix或者Exact路径类型一样。

Exact：精确匹配URL路径，并且区分大小写

Prefix: 根据URL中的，被/分割的前缀进行匹配。匹配区分大小写并且按照元素对路径进行匹配。path元素指的是路径中由/分隔符分隔的标签列表。

下面是ingress资源清单文件：

cat >ingress-http.yaml <<EOF
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-http
  namespace: dev
spec:
  ingressClassName: nginx
  rules:
  - host: nginx.test.com
    http:
      paths:
      - backend:
          service:
            name: nginx-service
            port: 
              number: 80
        path: /
        pathType: ImplementationSpecific
  - host: tomcat.test.com
    http:
      paths:
      - backend:
          service:
            name: tomcat-service
            port: 
              number: 80
        path: /
        pathType: ImplementationSpecific
EOF

使用方面和原来的旧版剩下基本相同。

创建测试pod：

 cat tomcat-nginx.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  namespace: dev
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx-pod
  template:
    metadata:
      labels:
        app: nginx-pod
    spec:
      containers:
      - name: nginx
        image: nginx:1.18
        ports:
        - containerPort: 80
      nodeName: k8s-node2
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: tomcat-deployment
  namespace: dev
spec:
  replicas: 1
  selector:
    matchLabels:
      app: tomcat-pod
  template:
    metadata:
      labels:
        app: tomcat-pod
    spec:
      containers:
      - name: tomcat
        image: tomcat:8.5-jre10-slim
        ports:
        - containerPort: 8080
      nodeName: k8s-node2

测试pod的service：

[root@k8s-master ~]# cat tomcat-nginx-svc.yaml 
---
apiVersion: v1
kind: Service
metadata:
  name: nginx-service
  namespace: dev
spec:
  ports:
    - port: 80
      name: nginx
  clusterIP: None
  selector:
    app: nginx-pod
---
apiVersion: v1
kind: Service
metadata:
  name: tomcat-service
  namespace: dev
spec:
  selector:
    app: tomcat-pod
  type: ClusterIP
  ports:
  - protocol: TCP
    port: 80
    targetPort: 8080

此时，应用上面的ingress资源yaml文件，可以看到绑定了10.109.115.193这个IP地址，但，实际访问的时候仍然是用节点IP+31080

[root@k8s-master ~]# kubectl get svc -n dev
NAME             TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)   AGE
nginx-service    ClusterIP   None             <none>        80/TCP    17h
tomcat-service   ClusterIP   10.104.157.194   <none>        80/TCP    17h
[root@k8s-master ~]# kubectl get ing  -n dev
NAME           CLASS   HOSTS                            ADDRESS          PORTS   AGE
ingress-http   nginx   nginx.test.com,tomcat.test.com   10.109.115.193   80      17h
[root@k8s-master ~]# kubectl get svc -n ingress-nginx 
NAME                                 TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE
ingress-nginx-controller             NodePort    10.109.115.193   <none>        80:31080/TCP,443:31111/TCP   5h21m
ingress-nginx-controller-admission   ClusterIP   10.110.7.6       <none>        443/TCP                      5h21m
