k8s1.25版本上实践 Ingress-nginx
背景：
领导要求的最新最新版本k8s。。。使用ingress-nginx 对外暴露内部服务
环境
| 节点 | master | worker |
| 主机/ip | calico-master01/192.168.195.135 | calico-work01/192.168.195.136 |
| k8s版本 | 1.25.2 | |
操作步骤：
1、部署nginx-ingress-controller
我这里是通过yaml配置文件部署的，文件地址：https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.4.0/deploy/static/provider/cloud/deploy.yaml

注意：这里面的镜像我换成国内的镜像了，不然拉不下来；还有nginx-ingress-controller的service类型改成了NodePort，默认的LoadBalance好像不支持
# 部署ingress相关的资源
kubectl apply -f deploy.yaml
其实这里在刚执行apply之后会有一个ingress-nginx-admission-patch的pod一直CrashbackOff，但是再等一会这个pod就自动删除了，不知道原因也没有去纠结这个点。
2、部署测试应用
# 创建一个测试用的namespace
kubectl create ns test-ns
# 创建httpd服务及其service与之关联
cat httpd.yaml //编写基于httpd服务的资源对象 kind: Deployment
apiVersion: apps/v1
metadata:
name: web01
namespace: test-ns
spec:
replicas: 3
selector:
matchLabels:
app: httpd01
template:
metadata:
labels:
app: httpd01
spec:
containers:

---
apiVersion: v1
kind: Service
metadata:
name: httpd-svc
namespace: test-ns
spec:
selector:
app: httpd01
ports:
- protocol: TCP
port: 80
targetPort: 80
# 创建tomcat服务及service
cat tomcat.yaml kind: Deployment
apiVersion: apps/v1
metadata:
name: web02
namespace: test-ns
spec:
replicas: 3
selector:
matchLabels:
app: tomcat01
template:
metadata:
labels:
app: tomcat01
spec:
containers:
- name: tomcat
image: tomcat:8.5.45
---
apiVersion: v1
kind: Service
metadata:
name: tomcat-svc
namespace: test-ns
spec:
selector:
app: tomcat01
ports:
- protocol: TCP
port: 8080
targetPort: 8080
确保以上资源创建成功
调用服务验证
以上通过service ip调用是正常返回。
3、配置ingress规则
cat ingress.yaml ---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-test
namespace: test-ns
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/use-regex: "true"
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- host: www.test01jf.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: httpd-svc
port:
number: 80
- path: /tomcat
pathType: Prefix
backend:
service:
name: tomcat-svc
port:
number: 8080
执行kubectl apply -f ingress.yaml 创建ingress资源对象
4、访问测试
到这里一个ingress的小实践就完成了，可以在命令行curl 验证，也可以通过浏览器访问测试
在浏览器测试需要配置本电脑的host解析，在命令行同样也许要，这里演示浏览器访问方式
扩展：配置https访问
1、创建证书存放目录
mkdir cert && cd cert
2、生成私钥nginx.key
openssl genrsa -out nginx.key 2048
3、使用nginx.key生成自签证书
openssl req -new -x509 -key nginx.key -days 10000 -out nginx.crt -subj /C=CN/ST=Shanghai/L=Shanghai/O=DevOps/CN=ingressnginx.com
4、创建secret对象
kubectl create secret tls ingress-nginx-secret --cert=nginx.crt --key=nginx.key
5、创建ingress规则
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-test
namespace: test-ns
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/use-regex: "true"
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
tls:
- hosts:
- www.test01jf.com
secretName: ingress-nginx-secret
rules:
- host: www.test01jf.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: httpd-svc
port:
number: 80
- path: /tomcat
pathType: Prefix
backend:
service:
name: tomcat-svc
port:
number: 8080
注意这里的ingress.yaml就是上面用到过的文件，只是加了tls那一段的配置，在k8s中可以重复的执行kubectl apply -f xxx.yaml文件来部署和更新资源，同样也可以通过kubectl delete -f xxx.yaml来删除资源，很方便。
