Components

• JAlgoArena
• JAlgoArena API

Continuous Delivery

• initially, developer push his changes to GitHub
• in next stage, GitHub notifies Travis CI about changes
• Travis CI runs whole continuous integration flow, running compilation, tests and generating reports
• application is deployed into Heroku machine

Infrastructure

• Heroku (PaaS)
• Spring Boot, Spring Cloud
• Netflix Eureka (discovery service)
• TravisCI - https://travis-ci.org/spolnik/JAlgoArena-Eureka

Running locally

There are two ways to run it - from sources or from binaries.

• Default port: 5000

Running from binaries

• go to releases page and download last app package (JAlgoArena-Eureka-[version_number].zip)
• after unpacking it, go to folder and run ./run.sh (to make it runnable, invoke command chmod +x run.sh)
• you can modify port in run.sh script, depending on your infrastructure settings. The script itself can be found in here: run.sh

Running from sources

• run git clone https://github.com/spolnik/JAlgoArena-Eureka to clone locally the sources
• now, you can build project with command ./gradlew clean bootRepackage which will create runnable jar package with app sources. Next, run java -Dserver.port=5000 -jar build\libs\jalgoarena-eureka-*.jar which will start application
• there is second way to run app with gradle. Instead of running above, you can just run ./gradlew clean bootRun
