Online code execution system is a scalable and robust code execution engine. Which can be plugged in existing system and can act as code judge

1. Server
2. Worker

Server contains all the controllers for interacting with workers.
It creates a new entry in database and at the same time in redis streams

Worker can be multiple instances that does the heavy lifting of running code.
Under the hood worker uses isolate library for running code in sandboxed environment.

Start with only one replica

docker compose -f compose-file.yml up --build

To start with 3 replica of worker

docker compose -f compose-file.yml up --build --scale worker=3

Above command will spin up 4 containers

1. server
2. worker
3. pgDB
4. redis

• Swagger UI is hosted on port http://localhost:8000/
• Redis Insight can be accessed on port http://localhost:8001/
• Postgres database can be connect on port 5432 using any db client

To stop containers

docker compose -f compose-file.yml down
