java-docker-images's Introduction

Java Docker Images

Repository to test different Docker images.

Project structure:

hello-app: Spring Boot app with simple REST controller.
images: printscreens.
taurus: scenarios script to run Taurus stress test.
ab-test: script to run a monitored Apache Bench test against a local process.

Build the App

First build the app with: sh build_app.sh.

Test the app: curl http://localhost:8080/greetings

Build the Docker images

Images:

OpenJDK
- docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.openjdk_11 .
Open J9
- docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.openj9_11 .
Open J9 Tuned (with CDS)
- docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.openj9_11_tuned .
Open J9 Tuned (with CDS, unpacked JAR and lazy inicialization)
- docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.openj9_11_unpacked_lazy .
GraalVM 20
- docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.graalvm_20 .
GraalVM 21 - Native
- docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.graalvm_native .

Stressing and Stats

Run any of the built Java images binding the port 8080.

Then run stress test with ApacheBench: sh run_stress_with_ab.sh

Monitoring docker stats: docker stats

Here is a sample from stats output after some minutes of idle (on my machine :p).

Under stressing:

Taurus

Run all containers: build_and_run_all.sh

Run Blazemeter container with Taurus tool: sh run_stress_with_taurus.sh
