Devops关键工具及技术(七)—基于Pipeline的Jmeter性能测试[一](Jmeter容器化)

上三篇文章中，我们从windows下Web自动化测试工具的安装再到将Web自动化测试工具RobotFramework+Selenium+Chome容器化，最后利用容器化后的自动化工具与Jenkins Docker Cloud集成，并在Pipeline中实现Web的自动化测试。
三篇文章链接见下：
Devops关键工具及技术(六)—基于Pipeline的Web自动化测试(Windows下自动化测试工具安装)
Devops关键工具及技术(六)—基于Pipeline的Web自动化测试(Web自动化测试工具容器化)
Devops关键工具及技术(六)—基于Pipeline的Web自动化测试(Web自动化测试的流水线集成)

有了自动化测试、自然性能测试也需要成为Pipeline的一部分。性能测试的工具常见的主要有Jmeter和LoadRunner。我们将选用Jmeter作为我们的主角。因为它是免费的。由于在Windows下安装Jmeter比较简单，所以我们在Jmeter性能测试会由两种文章来介绍。分别是Jmeter性能测试容器化、Jmeter性能测试的流水线集成。

本篇我们将先介绍Jmeter性能测试的容器化。
以下所有的文件代码都可以在Github找到:

1、容器化

Jmeter容器化的目的和Web自动化测试工具的容器化一样，是为了能够将Jmeter加入到我们的Jenkins中成为一个 节点，这样Jmeter将会很容易地集成到我们pipeline流水线中。
下面是Jmeter的Dockerfile文件

FROM openjdk:8-jdk

ENV http_proxy http://192.168.88.130:8118      //增加代理，如果无需代理可以删除
ENV https_proxy https://192.168.88.130:8118    //增加代理，如果无需代理可以删除

ENV JMETER_VERSION=5.0       //定义环境变量
ENV JMETER_HOME=/usr/local/apache-jmeter-${JMETER_VERSION}
ENV PATH=${JMETER_HOME}/bin:${PATH}

RUN apt-get -y update && \     //安装必要软件
apt-get -y install wget

RUN wget http://www.eu.apache.org/dist/jmeter/binaries/apache-jmeter-${JMETER_VERSION}.tgz && \
tar -xzf apache-jmeter-${JMETER_VERSION}.tgz -C /usr/local/    //下载Jmeter的包并解压

RUN rm -rf apache-jmeter-${JMETER_VERSION}.tgz \
${JMETER_HOME}/bin/examples \
${JMETER_HOME}/bin/templates \
${JMETER_HOME}/bin/*.cmd \
${JMETER_HOME}/bin/*.bat \
${JMETER_HOME}/docs \
${JMETER_HOME}/printable_docs && \
apt-get -y remove wget && \
apt-get -y --purge autoremove && \
apt-get -y clean && \
rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

ENV http_proxy ""
ENV https_proxy ""   //取消代理

根据Dockerfile镜像Docker的构建。

docker build -t jmeter:latest .

构建完成后运行

docker run --name jmeter -it -d jmeter:latest

测试

• 测试Jmeter容器化是否都已成功安装

[root@localhost ~]# docker ps

以上即是Jmeter容器化的内容，后面将会利用容器化后的镜像与Jenkins、Pipeline结合进行性能测试的集成
