Running JMeter tests in OpenShift using Jenkins Pipeline

Hello!



In this article, I want to share one of the ways to run JMeter performance tests in OpenShift using Jenkins as automation. First, we shall do all necessary actions (creation ImageStreams, BuildConfig, Joband so on) in the manual mode. After that, we will write Jenkins Pipeline.



:



  1. OpenShift (v3.11)
  2. Jenkins server OpenShift
  3. apache-jmeter-5.2.tgz
