User Defined Variables

This is a standard facility of JMeter: settings in a JMX test script may be defined symbolically and substituted at runtime via the commandline. These are called JMeter User Defined Variables or UDVs.

See test.sh and the trivial test plan.

Specifics

The Docker image built from the Dockerfile inherits from the Alpine Linux distribution:

"Alpine Linux is built around musl libc and busybox. This makes it smaller and more resource efficient than traditional GNU/Linux distributions. A container requires no more than 8 MB and a minimal installation to disk requires around 130 MB of storage. Not only do you get a fully-fledged Linux environment but a large selection of packages from the repository."

See https://hub.docker.com/_/alpine/ for Alpine Docker images.

The Docker image will install (via Alpine apk) several required packages most specificly the OpenJDK Java JRE. JMeter is installed by simply downloading/unpacking a .tgz archive from http://mirror.serversupportforum.de/apache/jmeter/binaries within the Docker image.

A generic entrypoint.sh is copied into the Docker image and will be the script that is run when the Docker container is run. The entrypoint.sh simply calls jmeter
