🥇使用 Jenkins Pipeline 在 OpenShift 中運行 JMeter 測試

大家好！

在本文中，我想分享使用 Jenkins 作為自動化在 OpenShift 中運行 JMeter 性能測試的方法之一。首先，我們將執行所有必要的步驟（創建 ImageStreams, BuildConfig, Job 等）在手動模式下。之後，我們來編寫Jenkins Pipeline。

作為一個起點，我們應該：

運行 OpenShift (v3.11) 集群
已配置憑據以在 OpenShift 中工作的 Jenkins 服務器
文件 apache-jmeter-5.2.tgz

作為測試，它會很簡單 HTTP Request 上 ya.ru 在一股流中。

在 OpenShift 中創建項目

讓我們從創建一個新環境開始。讓我們來創建 perftest 被一個團隊包圍：

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

我們會自動轉移到新創建的環境中 perftest，讓我們檢查一下是否是這樣：

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

創建存儲

測試報告將與網絡服務器共同存儲 jmeter-meter'一個地方 - /jmeter/reports.

最好現在創建 Storajs，因為 POD 將與其綁定 jmeter-web и jmeter-master.

您可以在官方文檔中找到有關存儲的更多詳細信息永久儲存.

讓我們創建 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

讓我們創造 PV и PVC 被 OpenShift 包圍：

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

檢查狀態 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 中的外觀如下：

創建 JMeter 基礎鏡像

讓我們繼續創建 ImageStream и BuildConfig.

您可以在文檔中找到所有必要的信息 - 構建和圖像流.

圖像構建策略是 Docker 來自當地來源。

讓我們創建一個基礎鏡像 jmeter-base，這將是基礎 jmeter-master.

Dockerfile

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

    type: Docker
  successfulBuildsHistoryLimit: 5
EOF

讓我們創建對象 IS и BC:

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

現在讓我們組裝基礎鏡像 jmeter-base:

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

JMeter 網頁版

jmeter-web 這是一個 Apache Web 服務器。它的任務是提供一個包含測試結果的目錄以供查看。

準備好的 Dockerfile 和配置文件 httpd.conf。對於指令 DocumentRoot 值集 /jmeter/reports， IE。保存測試結果的目錄。

Dockerfile

$ tee Dockerfile<<EOF
FROM httpd:2.4

讓我們創造 ImageStream и BuildConfig 對象：

$ oc create -f bc.yaml -n perftest

收集圖像 Dockerfile:

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

讓我們創建對象 Service и DeploymentConfig:

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

Jmeter大師

讓我們開始部署 Apache Web 服務器。

這是 Dockerfile jmeter-master'a，基於 jmeter-base，它將運行測試並將結果保存到存儲中。

Dockerfile

Dockerfile 為 jmeter-master，基於 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"]

運行sh

run.sh 這是一個運行 JMeter 並將結果保存到目錄的腳本 files.

每次啟動腳本時，它都會刪除以前的測試，因此您只能使用最新的數據。但這不是問題，因為您可以更改它以滿足您的需要。

#!/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

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}*

讓我們創造 IS и BC 對象：

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

我們收集 jmeter-master 圖像：

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

Job的用在 OpenShift'e 為了運行一個或多個 POD並保證執行命令/腳本後成功完成。

$ tee job.yaml<<EOF
apiVersion: batch/v1
kind: Job

  completions: 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

          imagePullPolicy: Always
      volumes:

          persistentVolumeClaim:
            claimName: jmeter-reports
      restartPolicy: Never
      terminationGracePeriodSeconds: 30
EOF

創建一個對象 Job:

$ oc create -f job.yaml -n perftest

讓我們檢查一下作業的狀態：

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

刪除 Job 讓我們使用命令：

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

詹金斯管道

現在自動化。讓我們再次回顧一下這些步驟：

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

下面是執行 OpenShift 存儲庫克隆、刪除和創建的管道 Job的。
