CodingBlocks Judge v2

This is CodingBlocks' new code judge

All required componenets are dockerized, so you can simply docker-compose up and get going ;)

Components

api : The API server

This is the judge api server It has 3 endpoints -

• /api/runs (to run code and get output)
• /api/submissions (to evaluate testcases)
• /api/langs (to show supported languages)

postgres : A PostgreSQL 9.6 DB

Standard postgres image Use docker-compose-withdb.yml if you want a new docker based DB created as part of the judge deployment

Use docker-compose.yml to use your own DB (If you have your own db server)

rabbitmq : An AMQP queue

Standard rabbitmq server to create queue of tasks

We use a standard RPC setup with a job_queue and a success_queue

taskmaster : The conductor of all workers

The taskmaster runs a worker when a task is received on the queue

worker-{lang} : Workers (for each language)

Available workers -

• cpp
• c
• java8
