Apache JMeter is a pure Java open-source software for load testing or performance testing. This article describes how to use the pressure measurement capability Alpine JMeter base image will be of container, combined with specific examples to demonstrate this mirrored the overall process used to build from.
Alpine constructed to mirror based JMeter
Alpine mirroring feature is the small mirror mounted above the Alpine jre, and JMeter download and unpack, set environment variables to complete the JMeter's image.
Dockerfile
- Dockerfile example is shown below
[root@liumiaocn jmeter]# ls
Dockerfile
[root@liumiaocn jmeter]# cat Dockerfile

Construction of JMeter Mirror
- Use docker build JMeter mirror constructed, as shown input log
[root@liumiaocn jmeter]# docker build -t jmeter:5.1.1 .

Test Preparation
Stress test application ready
In use port 8088 starts a Docker application Nginx local machine (in other ways may also be used), example is shown below:
liumiaocn:~ liumiao$ docker images |grep nginx |grep latest
nginx latest e445ab08b2be 2 months ago 126MB
liumiaocn:~ liumiao$ docker run -p 8088:80 -d --name=nginx-test nginx:latest
a80fb1a4fc20627891a6bd7394fd79ae9aefb7dc8cf72c12967bc2673a815308

Note: the preceding example Web application on a local pressure measurement, as set localhost hostname, but since jmeter run in a container, this localhost localhost different from each other, so here to the IP (192.168.31.242), the actual please modify for your own IP verification.
