Pre-requisites

1. Java Development Kit (8+).
2. Maven. Download from here and follow instructions to install here.

Steps to create a Docker image from sources:

Step 1) From the current directory (open-sourced-essim), run the following command:

mvn clean package

This should create essim.jar that will be available in the essim-engine\target\ folder and used in the next step.

Step 2) When Step 1 is successfully completed, run the following command to build the docker image from the same directory:

docker build -t [optional-repository/]<name-of-image>[:optional-image-version] essim-engine

Step 3) Done. You may now use this built image in your stack or push it to your favourite repository.

PS: Please take a look at essim-engine/Dockerfile to see what environment variables need to be defined.
PS: To execute in a non-Docker environment, you can use the jar generated after Step 1:

• Traverse to essim-engine\target\ and execute using the command java -Xms8G -XX:+UseParallelGC -XX:GCTimeRatio=9 -jar essim.jar.
• Also remember to define the environment variables (refer to essim-engine/Dockerfile) in your execution environment.
