使用Docker 部署Jmeter非常方便，可以省略软件的安装以及配置，比如jdk、jmeter。需要部署多个工作节点可以节省时间。

1. 控制节点（Master-主节点）只有一个，可以使用图形化的界面，方便操作
2. 工作节点（Slave-从节点）使用Docker部署Jmeter镜像，工作节点的数量越多越好。
3. 控制节点使用RMI 调用工作节点
4. 控制节点测试计划设置的线程数量约等于工作节点宿主机能同时工作的线程数，这样能真实模拟用户同时发起的请求，压测的结果也准确些

制作Jmeter基础镜像

1. 下载jmeter安装包 https://archive.apache.org/dist/jmeter/binaries/apache-jmeter-5.6.3.tgz
2. 编写 Dockerfile

FROM openjdk:8-jdk-alpine3.9
ARG JMETER_VERSION=5.6.3# 设置工作目录
WORKDIR /opt/jmeter# 复制 Jmeter
COPY apache-jmeter-${JMETER_VERSION}.tgz   ./# 安装
RUN tar -xvzf apache-jmeter-$JMETER_VERSION.tgz \&& rm apache-jmeter-$JMETER_VERSION.tgz# 设置环境变量
ENV JMETER_HOME /opt/jmeter/apache-jmeter-$JMETER_VERSION/
ENV PATH="$JMETER_HOME/bin:${PATH}"

3. 文件目录关系如下

root@ubuntu:/home/chengdu/jmeter/docker# tree
.
├── apache-jmeter-5.6.3.tgz
├── Dockerfile
└── worker└── Dockerfile.worker

4. 执行编译镜像命令

docker build -t jmeter:5.6.3 .

5. 查看镜像是否编译成功

root@ubuntu:/home/chengdu/jmeter/docker# docker images|grep jmeter
jmeter                   5.6.3             37a73dacbe58   4 hours ago     342MB
jmeter-5.6.3             worker            80ae9383e488   4 hours ago     342MB

制作工作节点镜像

基于第一步的基础镜像制作

FROM jmeter:5.6.3# 默认使用1099端口，可以用参数覆盖
ARG RMI_PORT=1099
ARG LOCAL_PORT=50000ENTRYPOINT $JMETER_HOME/bin/jmeter-server \-Dserver_port=${RMI_PORT} \-Dserver.rmi.localport=${LOCAL_PORT} \-Djava.rmi.server.hostname=${HOST_IP} \-Jserver.rmi.ssl.disable=true

保存为 Dockerfile.worker，运行编译镜像命令

docker build -f Dockerfile.worker -t jmeter-5.6.3:worker .

启动工作节点

启动3个工作节点，注意，HOST_IP 变量可以填写宿主机的IP，确保控制节点的网络能当前的宿主机

docker run -p 1099:1099 -p 50000:50000 -e RMI_PORT=1099 -e LOCAL_PORT=50000 -e HOST_IP=192.168.230.128 -it -d --name jmeter-worker-01 jmeter-5.6.3:workerdocker run -p 1100:1100 -p 50001:50001 -e RMI_PORT=1100 -e LOCAL_PORT=50001 -e HOST_IP=192.168.230.128 -it -d --name jmeter-worker-02 jmeter-5.6.3:workerdocker run -p 1101:1101 -p 50002:50002 -e RMI_PORT=1101 -e LOCAL_PORT=50002 -e HOST_IP=192.168.230.128 -it -d --name jmeter-worker-03 jmeter-5.6.3:worker

查看是容器否启动成功了 docker ps

启动控制节点

1. 修该 jmeter.properties 的 remote_hosts 配置

remote_hosts = 192.168.230.128:1099,192.168.230.128:1100,192.168.230.128:1101

2. 启动控制节点，windows 直接点击 jmeter.bat，启动成功之后会看到3个配置的节点
   
3. 点击远程启动所有
4. 在容器中查看执行日志
   docker exec -it 98300e4cdea0 /bin/sh 进入容器shell 终端，可以看到有一个日志文件 jmeter-server.log

root@ubuntu:/home/chengdu/jmeter/docker/worker# docker exec -it 98300e4cdea0 /bin/sh
/opt/jmeter # ls
apache-jmeter-5.6.3  jmeter-server.log
