kubernetes之安装ingress-nginx（k8s1.19版本之后）

1. 项目地址

ingress-nginx项目地址

2. 操作环节

root@master1:~# kubectl apply -f nginx-ingress-controller/manifests/root@master1:~# kubectl get pods -n ingress-nginx 
NAME                                        READY   STATUS      RESTARTS   AGE
ingress-nginx-admission-create-w768p        0/1     Completed   0          63m
ingress-nginx-admission-patch-hgrhz         0/1     Completed   2          63m
ingress-nginx-controller-85858f5dc4-xvzgd   1/1     Running     0          63m

3. 测试

3.1 部署nginx及tomcat

编写tomcat-deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:name: nginx-deploymentnamespace: dev
spec:replicas: 3selector:matchLabels:app: nginx-podtemplate:metadata:labels:app: nginx-podspec:containers:- name: nginximage: nginx:1.17.1ports:- containerPort: 80---apiVersion: apps/v1
kind: Deployment
metadata:name: tomcat-deploymentnamespace: dev

spec:selector:app: tomcat-podclusterIP: Nonetype: ClusterIPports:- port: 8080targetPort: 8080

部署

root@master1:~/yaml# kubectl apply -f tomcat-deploy.yaml

查看

root@master1:~/yaml# kubectl get pods -n dev
NAME                                 READY   STATUS    RESTARTS   AGE

tomcat-deployment-7ff7bd5bcd-m27tf   1/1     Running   0          89m

这里看到 已经成功部署测试用的tomecat及nginx

3.2 部署ingress

通过kubectl api-resources | grep ingress查看到ingress的版本是 networking.k8s.io/v1

部署ingress-http.com

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:name: ingress-httpnamespace: dev
spec:rules:- host: nginx.wzq.comhttp:paths:- backend:service: name: nginx-serviceport:number: 80path: /pathType: Prefix

root@master1:~/yaml# kubectl get ingress -n dev
