Docker swarm环境下部署JMETER集群-分布式压测

Docker compose yuml文件编写

本文默认你已经使用docker swarm搭建好了docker集群环境

若需要加入已经存在的网络

若需要将服务加入已经存在的网络则将networks:部分替换为

networks:
  swarmnet:
    name: swarmnet
    external: true

使用的镜像介绍

1.zhangyx1619/jmeter-master:orcaljdk17-jmeter5.5-graphs-plugins-release
jmeter主节点
2.zhangyx1619/jmeter-master:orcaljdk17-jmeter5.5-graphs-plugins-release
jmeter从节点
镜像含有jmeter-plugins-manager ,jmeter-plugins-perfmon,mysql-connector-java,jmeter-plugins-graphs-basic插件，并自带了压测脚本例子 helloword.jmx

部署集群

在docker swarm主节点执行

 docker stack deploy -c Docker compose yuml文件 jmeter

查看服务部署情况

docker stack services jmeter

执行分布式压测

在jmeter-master所在节点执行命令

docker exec -it jmeter-master容器id或者名称 jmeter  -n -t /usr/local/jmeter/apache-jmeter-5.5/work_space/helloWord.jmx -r -l /usr/local/jmeter/apache-jmeter-5.5/work_space/result.jtl -e -o /usr/local/jmeter/apache-jmeter-5.5/work_space/html/ 

jmeter命令options

1. -n 以非图形化方式执行
2. -t 指定需要执行压测脚本
3. -r 启动所有jmeter节点执行压测任务
4. -l 指定输出压测结果的文件
5. -e 将压测结果导出成html
6. -o 指定html输出路径
