第一,测试VIP漂移
1、查看 vip 是否绑定成功
打开 安装了 keeplived的MASTER主节点机器,
ip addr
ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:0c:29:79:9e:36 brd ff:ff:ff:ff:ff:ff inet 192.168.1.62/24 brd 192.168.40.255 scope global noprefixroute ens33 valid_lft forever preferred_lft forever inet 192.168.1.199/24 scope global secondary ens33
...
看到 "inet 192.168.1.199/24 scope global secondary ens33" 类似这样,说明成功了。
2、测试vip漂移
(1) 停止 keeplived的主节点,VIP会漂移到备份节点
service keepalived stop
(2)开始Keeplived的主节点,VIP又会漂移回主节点。
service keepalived start
第二、测试 Ingress HTTP 代理 k8s 内部站点
k8s的master节点上创建一个pod,和ingress. yaml文件如下:
apiVersion: v1 kind: Service metadata: name: tomcat namespace: default spec: selector: app: tomcat release: canary ports: - name: http targetPort: 8080 port: 8080 - name: ajp targetPort: 8009 port: 8009 --- apiVersion: apps/v1 kind: Deployment metadata: name: tomcat-deploy namespace: default spec: replicas: 2 selector: matchLabels: app: tomcat release: canary template: metadata: labels: app: tomcat release: canary spec: containers: - name: tomcat image: tomcat:8.5.34-jre8-alpine imagePullPolicy: IfNotPresent ports: - name: http containerPort: 8080 name: ajp containerPort: 8009 --- apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: ingress-myapp namespace: default annotations: kubernetes.io/ingress.class: "nginx" spec: rules: - host: tomcat.lucky.com http: paths: - path: / pathType: Prefix backend: service: name: tomcat port: number: 8080
我们看到 ingress的域名设置为 tomcat.lucky.com 。
本地host添加
192.168.157.199 tomcat.lucky.com
然后访问 http://tomcat.lucky.com/,通了,说明已经安装成功了。
