1> 创建测试资源
1.命令获取deployment yaml模板
kubectl create deployment web --image=nginx:1.14 -o yaml --dry-run >deploy-web.yaml
修改deployment -web模板，添加pod限制
apiVersion: apps/v1 kind: Deployment metadata: labels: app: web name: web spec: replicas: 1 selector: matchLabels: app: web template: metadata: labels: app: web spec: containers: - image: nginx:1.14 name: nginx resources: limits: cpu: 200m memory: 200Mi requests: cpu: 200m memory: 200Mi
创建deployment-web
[root@k8s-master1 hpa]# kubectl create -f deploy-web.yaml
2.生成autoscale yaml模板
[root@k8s-master1 hpa]# kubectl autoscale deployment web --min=2 --max=10 -o yaml --dry-run >hpa-web.yaml
修改hpa-web模板
apiVersion: autoscaling/v1 kind: HorizontalPodAutoscaler metadata: name: web spec: maxReplicas: 10 minReplicas: 2 scaleTargetRef: apiVersion: apps/v1 kind: Deployment name: web targetCPUUtilizationPercentage: 40
创建hpa-web
[root@k8s-master1 hpa]# kubectl create -f hpa-web.yaml
horizontalpodautoscaler.autoscaling/web created
查看信息（web已经自动扩容为2个）
[root@k8s-master1 hpa]# kubectl get pod,hpa NAME READY STATUS RESTARTS AGE pod/busybox-97b9f6974-grtzd 1/1 Running 0 22h pod/test-74695b8467-8lwrq 1/1 Running 0 12m pod/web-5f8765dd69-dzv6l 1/1 Running 0 5m44s pod/web-5f8765dd69-pq2nv 1/1 Running 0 5m58s NAME REFERENCE TARGETS MINPODS MAXPODS REPLICAS AGE horizontalpodautoscaler.autoscaling/web Deployment/web 0%/40% 2 10 2 23s
3.创建service yaml模板
[root@k8s-master1 hpa]# kubectl create service nodeport web --tcp=80:80 -o yaml --dry-run >service-web.yaml
修改service-web模板
apiVersion: v1 kind: Service metadata: labels: app: web name: web spec: ports: - name: web port: 80 protocol: TCP targetPort: 80 selector: app: web type: NodePort
创建service
[root@k8s-master1 hpa]# kubectl create -f service-web.yaml
service/web created
2> 查看刚刚创建的资源
[root@k8s-master1 ~]# kubectl get pod,deploy,svc,hpa -o wide NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES pod/busybox-97b9f6974-grtzd 1/1 Running 0 22h 10.244.169.154 k8s-node2 <none> <none> pod/test-74695b8467-8lwrq 1/1 Running 0 21m 10.244.107.194 k8s-node3 <none> <none> pod/web-5f8765dd69-dzv6l 1/1 Running 0 14m 10.244.36.98 k8s-node1 <none> <none> pod/web-5f8765dd69-pq2nv 1/1 Running 0 14m 10.244.107.195 k8s-node3 <none> <none> NAME READY UP-TO-DATE AVAILABLE AGE CONTAINERS IMAGES SELECTOR deployment.apps/busybox 1/1 1 1 2d20h busybox busybox run=busybox deployment.apps/test 1/1 1 1 21m test nginx:1.14 run=test deployment.apps/web 2/2 2 2 24m nginx nginx:1.14 app=web NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR service/kubernetes ClusterIP 10.0.0.1 <none> 443/TCP 42d <none> service/web NodePort 10.0.0.81 <none> 80:30779/TCP 4m21s app=web NAME REFERENCE TARGETS MINPODS MAXPODS REPLICAS AGE horizontalpodautoscaler.autoscaling/web Deployment/web 0%/40% 2 10 2 9m25s
3> 安装ab进行测试
[root@k8s-master1 ~]# ab -n 1000000 -c 10 -k http://10.0.0.81/ This is ApacheBench, Version 2.3 <$Revision: 1430300 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking 10.0.0.81 (be patient)
查看pod日志
[root@k8s-master1 ~]# kubectl logs web-5f8765dd69-dzv6l -f 10.23.215.240 - - [09/Jul/2020:06:33:17 +0000] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3" "-" 10.23.215.240 - - [09/Jul/2020:06:33:17 +0000] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3" "-" 10.23.215.240 - - [09/Jul/2020:06:33:17 +0000] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3" "-" 10.23.215.240 - - [09/Jul/2020:06:33:17 +0000] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3" "-" 10.23.215.240 - - [09/Jul/2020:06:33:17 +0000] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3" "-"
