# Java Docker Images
Repository to test different Docker images.
Project structure:
* *hello-app*: Spring Boot app with simple REST controller.
* *hello-app-native*: Spring Boot app with simple REST controller and Native plugin.
* *images*: printscreens.
* *taurus*: scenarios script to run Taurus stress test.
* *ab-test*: script to run a monitored Apache Bench test against a local process.
Recommendations:
* always unpack the JAR
## 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 - CDS
* `docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.openj9_11_tuned .`
* Open J9 Tuned - Unpacked, CDS, Lazy Inicialization
* `docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.openj9_11_unpacked_lazy .`
* GraalVM 21 - JVM
* `docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.graalvm_21 .`
* GraalVM 21 - Native
* `docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.graalvm_native .`
* Liberica JVM 21 - AOT and CDS
* `docker build -t wesleyegberto/hello-app:minimal -f Dockerfile.liberica_21_cds .`
## 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`
## TODO
* [x] Spring Boot splitting the lib and classes
* [x] Spring Boot Native build
* [x] Spring Boot Native with GraalVM
* [x] Spring Boot with AOT and CDS
