- Notes
- API Gateway is the single point forwarding to destination service. It's using Eureka for identifying url/addresses of the services just based on their names. Additionally - it has configured client load balancer (Netflix Ribbon) - which load balance requests - it's mainly used in JAlgoArena for many Judge Agents - as they are stateless services and considerably slowest part of JAlgoArena infrastructure.
- 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
- Heroku (PaaS)
- Spring Boot, Spring Cloud
- Netflix Zuul (api gateway), Ribbon (load balancer), Hystrix (circut breaker)
- TravisCI - https://travis-ci.org/spolnik/JAlgoArena-API
There are two ways to run it - from sources or from binaries.
- Default port:
5001
- go to releases page and download last app package (JAlgoArena-API-[version_number].zip)
- after unpacking it, go to folder and run
./run.sh(to make it runnable, invoke commandchmod +x run.sh) - you can modify port and Eureka service url in run.sh script, depending on your infrastructure settings. The script itself can be found in here: run.sh
- run
git clone https://github.com/spolnik/JAlgoArena-APIto clone locally the sources - now, you can build project with command
./gradlew clean bootRepackagewhich will create runnable jar package with app sources. Next, runjava -Dserver.port=5001 -jar build\libs\jalgoarena-api-*.jarwhich will start application - there is second way to run app with gradle. Instead of running above, you can just run
./gradlew clean bootRun
