一、前提条件
Kubernetes > 1.16
二、部署拓扑
可以从 master 节点启动测试,master 节点把对应的测试脚本发送到对应的 slaves 节点,slave 节点的 pod/nodes 主要作用即发压。
部署文件清单:
jmeter_cluster_create.sh
— 此脚本将要求一个唯一的 namespace,然后它将继续创建命名空间和所有组件(jmeter master,slaves,influxdb 和 grafana)。
注意:在启动前,请在jmeter_slaves_deploy.yaml
文件中设置要用于 slaves 服务器的副本数,通常副本数应与拥有的 worker nodes 相匹配。
jmeter_master_configmap.yaml
— Jmeter master 的应用配置。
jmeter_master_deployment.yaml
— Jmeter master 的部署清单。
jmeter_slaves_deploy.yaml
— Jmeter slave 的部署清单。
jmeter_slave_svc.yaml
— jmeter slave 的服务清单。使用 headless service,这使我们能够直接获取 jmeter slave 的 POD IP 地址,而我们不需要 DNS 或轮询。创建此文件是为了使 slave Pod IP 地址更容易直接发送到 jmeter master。
jmeter_influxdb_configmap.yaml
— influxdb 部署的应用配置。如果要在默认的 influxdb 端口之外使用 graphite 存储方法,这会将 influxdb 配置为暴露端口 2003,以便支持 graphite 。因此,可以使用 influxdb 部署来支持 jmeter 后置监听器方法(graphite 和 influxdb)。
jmeter_influxdb_deploy.yaml
— Influxdb 的部署清单
jmeter_influxdb_svc.yaml
— Influxdb 的服务清单。
jmeter_grafana_deploy.yaml
— grafana 部署清单。
jmeter_grafana_svc.yaml
— grafana 部署的服务清单,默认情况下使用 NodePort,如果公有云中运行它,则可以将其更改为 LoadBalancer(并且可以设置 CNAME 以使用 FQDN 缩短名称)。
dashboard.sh
— 该脚本用于自动创建以下内容:
(1)influxdb pod 中的一个 influxdb 数据库(Jmeter)
(2)grafana 中的数据源(jmeterdb)
start_test.sh
—此脚本用于自动运行 Jmeter 测试脚本,而无需手动登录 Jmeter 主 shell,它将询问 Jmeter 测试脚本的位置,然后将其复制到 Jmeter master pod 并启动自动对 Jmeter slave 进行测试。
jmeter_stop.sh
- 停止测试
GrafanaJMeterTemplate.json
— 预先构建的 Jmeter grafana 仪表板。
Dockerfile-base
- 构建 Jmeter 基础镜像
Dockerfile-master
- 构建 Jmeter master 镜像
Dockerfile-slave
- 构建 Jmeter slave 镜像
Dockerimages.sh
- 批量构建 docker 镜像
三、docker 镜像
1、构建 docker 镜像
执行脚本,构建镜像:
查看镜像:
将镜像推送到 Registry:
$ sudo docker login --username=xxxx registry.cn-beijing.aliyuncs.com
$ sudo docker tag [ImageId] registry.cn-beijing.aliyuncs.com/7d/jmeter-base:[镜像版本号]
$ sudo docker push registry.cn-beijing.aliyuncs.com/7d/jmeter-base:[镜像版本号]
复制代码
2、部署清单
Dockerfile-base (构建 Jmeter 基础镜像):

四、Kubernetes 部署
1、部署组件
执行jmeter_cluster_create.sh
,并输入一个唯一的 namespace
./jmeter_cluster_create.sh
复制代码
等待一会,查看 pods 安装情况:
$ kubectl get pods -n 7dgroup
NAME READY STATUS RESTARTS AGE
influxdb-jmeter-584cf69759-j5m85 1/1 Running 2 5m
jmeter-grafana-6d5b75b7f6-57dxj 1/1 Running 1 5m

jmeter-slaves-b5b75757-n58jw 1/1 Running 0 5m
复制代码
2、部署清单

五、初始化 dashboard
1、启动 dashboard 脚本
检查 service 部署情况:
$ kubectl get svc -n 7dgroup
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
jmeter-grafana NodePort 10.96.6.201 <none> 3000:31801/TCP 10m
jmeter-influxdb ClusterIP 10.96.111.60 <none> 8083/TCP,8086/TCP,2003/TCP 10m
jmeter-slaves-svc ClusterIP None <none> 1099/TCP,50000/TCP 10m
复制代码
我们可以通过 http://任意 node_ip:31801/
访问 grafana
最后,我们在 grafana 导入 dashborad 模版:
如果你不喜欢这个模版,也可以导入热门模版:5496
2、部署清单
dashboard.sh
该脚本用于自动创建以下内容:
#!/usr/bin/env bash
working_dir=`pwd`
#Get namesapce variable
tenant=`awk '{print $NF}' $working_dir/tenant_export`
## Create jmeter database automatically in Influxdb
echo "Creating Influxdb jmeter Database"
##Wait until Influxdb Deployment is up and running
##influxdb_status=`kubectl get po -n $tenant | grep influxdb-jmeter | awk '{print $2}' | grep Running
influxdb_pod=`kubectl get po -n $tenant | grep influxdb-jmeter | awk '{print $1}'`
kubectl exec -ti -n $tenant $influxdb_pod -- influx -execute 'CREATE DATABASE jmeter'
## Create the influxdb datasource in Grafana
echo "Creating the Influxdb data source"
grafana_pod=`kubectl get po -n $tenant | grep jmeter-grafana | awk '{print $1}'`
## Make load test script in Jmeter master pod executable
#Get Master pod details
master_pod=`kubectl get po -n $tenant | grep jmeter-master | awk '{print $1}'`
kubectl exec -ti -n $tenant $master_pod -- cp -r /load_test /![]()jmeter/load_test
kubectl exec -ti -n $tenant $master_pod -- chmod 755 /jmeter/load_test
##kubectl cp $working_dir/influxdb-jmeter-datasource.json -n $tenant $grafana_pod:/influxdb-jmeter-datasource.json
kubectl exec -ti -n $tenant $grafana_pod -- curl 'http://admin:admin@127.0.0.1:3000/api/datasources' -X POST -H 'Content-Type: application/json;charset=UTF-8' --data-binary '{"name":"jmeterdb","type":"influxdb","url":"http://jmeter-influxdb:8086","access":"proxy","isDefault":true,"database":"jmeter","user":"admin","password":"admin"}'
复制代码
六、启动测试
1、执行脚本

$ ./start_test.sh
Enter path to the jmx file web-test.jmx
''SLF4J: Class path contains multiple SLF4J bindings.
