🥇使用 Jenkins Pipeline 在 OpenShift 中运行 JMeter 测试

您好！

在本文中，我想分享使用 Jenkins 作为自动化在 OpenShift 中运行 JMeter 性能测试的方法之一。首先，我们将执行所有必要的步骤（创建 ImageStreams, BuildConfig, Job 等）在手动模式下。之后，我们来编写Jenkins Pipeline。

作为一个起点，我们应该：

运行 OpenShift (v3.11) 集群
已配置凭据以在 OpenShift 中工作的 Jenkins 服务器
文件 apache-jmeter-5.2.tgz

作为测试，它会很简单 HTTP Request 上 ya.ru 在一股流中。

在 OpenShift 中创建项目

让我们从创建一个新环境开始。让我们来创建 perftest 被一个团队包围：

$ oc new-project perftest --display-name="Performance Tests" --description="Performance Tests - JMeter"

我们会自动转移到新创建的环境中 perftest，让我们检查一下是否是这样：

$ oc project
Using project "perftest" on server "https://127.0.0.1:8443".

创建存储

测试报告将与网络服务器共同存储 jmeter-meter'一个地方 - /jmeter/reports.

最好现在创建 Storajs，因为 POD 将与其绑定 jmeter-web и jmeter-master.

您可以在官方文档中找到有关存储的更多详细信息永久储存.

让我们创建 yaml 文件 PV и PVC.

pv.yaml

$ tee pv.yaml<<EOF
apiVersion: v1
kind: PersistentVolume
metadata:
  name: jmeter-reports
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteMany
  glusterfs:
    endpoints: glusterfs-cluster
    path: /jmeter/reports
    readOnly: false
  persistentVolumeReclaimPolicy: Retain
EOF

PVC.yaml

$ tee pvc.yaml<<EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: jmeter-reports
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Gi
EOF

让我们创造 PV и PVC 被 OpenShift 包围：

$ oc create -f pv.yaml -n perftest
$ oc create -f pvc.yaml -n perftest

检查状态 PVC:

$ oc get pvc -n perftest
NAME             STATUS    VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS        AGE
jmeter-reports   Bound     pvc-b0e5f152-db4b-11ea-a497-566f75280024   10Gi       RWX            glusterfs-storage   8m

GUI 中的外观如下：

创建 JMeter 基础镜像

让我们继续创建 ImageStream и BuildConfig.

您可以在文档中找到所有必要的信息 - 构建和图像流.

图像构建策略是 Docker 来自当地来源。

让我们创建一个基础镜像 jmeter-base，这将是基础 jmeter-master.

Dockerfile

FROM openjdk:8u212-jdk

ARG JMETER_VER="5.2"
ENV JMETER_HOME /jmeter/apache-jmeter-$JMETER_VER
ENV PATH $JMETER_HOME/bin:$PATH

RUN mkdir -p /jmeter/results 
    && mkdir /jmeter/tests

WORKDIR /jmeter

COPY apache-jmeter-$JMETER_VER.tgz .

RUN tar -xzf $JMETER_HOME.tgz 
    && rm $JMETER_HOME.tgz 
    && ls -la

RUN sed -i s/#server.rmi.ssl.disable=false/server.rmi.ssl.disable=true/ $JMETER_HOME/bin/jmeter.properties

EXPOSE 60000

is.yaml

$ tee is.yaml<<EOF

        kind: ImageStreamTag
        name: 'openjdk:8u212-jdk'
    type: Docker
  successfulBuildsHistoryLimit: 5
EOF

让我们创建对象 IS и BC:

$ oc create -f is.yaml -n perftest
$ oc create -f bc.yaml -n perftest

现在让我们组装基础镜像 jmeter-base:

$ oc start-build jmeter-base -n perftest --from-dir=. --follow

JMeter 网页版

jmeter-web 这是一个 Apache Web 服务器。它的任务是提供一个包含测试结果的目录以供查看。

准备好了 Dockerfile 和配置文件 httpd.conf。对于指令 DocumentRoot 值集 /jmeter/reports， IE。保存测试结果的目录。

Dockerfile

$ tee Dockerfile<<EOF
FROM httpd:2.4

COPY httpd.conf /usr/local/apache2/conf/httpd.conf
RUN chmod -R 777 /usr/local/apache2/logs

EXPOSE 8080

CMD ["httpd", "-D", "FOREGROUND"]
EOF

      from:
        kind: ImageStreamTag
        name: 'httpd:2.4'
    type: Docker
  successfulBuildsHistoryLimit: 5
EOF

让我们创造 ImageStream и BuildConfig 对象：

$ oc create -f is.yaml -n perftest
$ oc create -f bc.yaml -n perftest

收集图像 Dockerfile:

$ oc start-build jmeter-web -n perftest --from-dir=. --follow

让我们创建对象 Service и DeploymentConfig:

$ oc create -f sc.yaml -n perftest
$ oc create -f dc.yaml -n perftest

Jmeter大师

让我们开始部署 Apache Web 服务器。

这是 Dockerfile jmeter-master'a，基于 jmeter-base，它将运行测试并将结果保存到存储中。

Dockerfile

Dockerfile 为 jmeter-master，基于 jmeter-base.

FROM jmeter-base

ARG JMETER_VER="5.2"
ENV JMETER_HOME /jmeter/apache-jmeter-$JMETER_VER
ENV PATH $JMETER_HOME/bin:$PATH

WORKDIR /jmeter
COPY run.sh /jmeter/
COPY tests/*.jmx /jmeter/tests/
RUN chmod +x /jmeter/run.sh

ENTRYPOINT ["/bin/bash"]
CMD ["/jmeter/run.sh"]

运行

run.sh 这是一个运行 JMeter 并将结果保存到目录的脚本 files.

每次启动脚本时，它都会删除以前的测试，因此您只能使用最新的数据。但这不是问题，因为您可以更改它以满足您的需要。

#!/bin/bash

set -e

if [ -d "/jmeter/reports/files" ]
then
    echo "Directory /jmeter/reports/files exist - OK"
else
    echo "Creating /jmeter/reports/files directory"
    mkdir /jmeter/reports/files
fi

if [ -d "/jmeter/reports/dashboards" ]
then
    echo "Directory /jmeter/reports/dashboards exist"
else
    echo "Creating /jmeter/reports/dashboards directory"
    mkdir /jmeter/reports/dashboards
fi

echo "*** JMeter START Tests ***"

for item in $(ls -1 /jmeter/tests | grep jmx)
do
    echo "*** Removing dashboard directory for $item"
    rm -rdf /jmeter/reports/dashboards/${item}*

    echo "*** Removing tests directory for $item"
    rm -rdf /jmeter/reports/files/${item}*

    echo "*** Testing a $item file ***"
    jmeter -n -t /jmeter/tests/${item} -l /jmeter/reports/files/${item}-report.jtl -e -o /jmeter/reports/dashboards/${item}-dash
done

$ tee is.yaml<<EOF

      from:
        kind: ImageStreamTag
        name: 'jmeter-base:latest'
    type: Docker
  successfulBuildsHistoryLimit: 5
EOF

让我们创造 IS и BC 对象：

$ oc create -f is.yaml -n perftest
$ oc create -f bc.yaml -n perftest

我们收集 jmeter-master 图像：

$ oc start-build jmeter-master -n perftest --from-dir=. --follow

工作

Job的用在 OpenShift'e 为了运行一个或多个 POD并保证执行命令/脚本后成功完成。

$ tee job.yaml<<EOF
apiVersion: batch/v1
kind: Job
metadata:
  name: jmeter-master
  labels:
    jobName: jmeter-master
spec:
  completions: 1
  parallelism: 1
  template:
    metadata:
      name: jmeter-master
      labels:
        jobName: jmeter-master
    spec:
      containers:
        - name: jmeter-master
          image: 172.30.1.1:5000/perftest/jmeter-master:latest
          volumeMounts:
            - mountPath: /jmeter/reports
              name: jmeter-reports
          imagePullPolicy: Always
      volumes:
        - name: jmeter-reports
          persistentVolumeClaim:
            claimName: jmeter-reports
      restartPolicy: Never
      terminationGracePeriodSeconds: 30
EOF

创建一个对象 Job:

$ oc create -f job.yaml -n perftest

让我们检查一下作业的状态：

$ oc get jobs -n perftest
NAME            DESIRED   SUCCESSFUL   AGE
jmeter-master   1         1            5m

删除 Job 让我们使用命令：

$ oc delete jobs/jmeter-master -n perftest --ignore-not-found=true

詹金斯管道

现在自动化。让我们再次回顾一下这些步骤：

git clone
oc whoami -t
oc start-build ...
oc delete jobs/jmeter-master
oc create -f job.yaml -n perftest

下面是执行存储库克隆、删除和 OpenShift 创建的管道 Job的。

Pipeline完成运行后，我们将收到电子邮件通知 '[email protected] 从 [email protected].

通过点击链接 http://jmeter-web.127.0.0.1.nip.io/ 我们会看到目录 files，存储测试报告：
