Rurikawa

Rurikawa is a simple Docker-based online judge system for complex multi-file projects with changing building scripts and multi-stage assignments.

Rurikawa（琉璃河琉璃川）是一个简易的自动评测系统，主要面向构建流程多变、复杂的多文件项目，以及多阶段的作业。

Features

• Online judging system
• Git repository submission (plus, it's the only way to submit, so you always have your submission versioned)
• Customize assignment building scripts using Dockerfile
• Standalone judgers (judger tags coming soon™)
• "Special judge" scripts for complex judging dynamic scoring Not yet available in v0.5.0
• Horizontally-scalable backend design

Not-yet implemented

• I18n (Currently only supports Chinese)

Building

Building coordinator requires the following tools:

• DotNet 5 SDK

Building web requires the following tools:

• NodeJS v12+
• Yarn 1.22+

Building judger requires the following tools:

• Rust 1.56+
• GCC or Clang that support C11

Running

Before running

You'll need these tools to run a Rurikawa server (coordinator + web):

• A PostgreSQL-compatible database (You can try CockroachDB, though it hasn't been tested).
• A Amazon S3-compatible object storage service (I would recommend Minio if you're serving your own files).
• Redis.
• Any recent version of git inside coordinator environment.

You can refer to the development docker compose file (dev.docker-compose.yml) for an example.

You'll need these tools to run a Rurikawa judger:

• A Unix-family operating system (Sadly, windows doesn't work for now).
• Any recent version of git.
• Any recent version of docker, with API exposed at the default path.
  • You might need to log into a paid account if your clients use many different kinds of build environments - Docker now limits access rates for unpaid accounts.
  • You might need to run docuum to manage Docker's build image cache.

You can check out the corresponding dockerfiles provided for detailed building instructions.

Backend

Configure coordinator/appsettings.json before running:

{
  // These parts are for controlling logging behavior. Change if you need.
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },

  // Enter information about your database here:
  "pgsqlLink": "Host=<host>;Database=<db>;Port=<port>;Username=<username>;Password=<password>",

  // Enter your Redis host here:
  "redisLink": "<redis>",

  // Enter information about your OSS here:
  "testStorage": {
    "endpoint": "<your_endpoint>",
    "accessKey": "<your_access_key>",
    "secretKey": "<your_secret_key>",
    "bucket": "<your_bucket>",
    "ssl": true
  }
}

You can find an example of this file at coordinator/appsettings.dev.json.

You'll also need an ECDSA private key in PFX format next to the coordinator CWD, as certs/dev.pfx (Subject to change), in order to sign JWTs.

To run coordinator, run:

$ dotnet run

Judger

You'll need coordinator running before running judger.

To run the judger the first time, you'll need a register token from coordinator. Visit <your_web_host>/admin/judger to get a token, and then run:

$ path/to/rurikawa connect <your_coordinator_host> --register-token <token>

In subsequent runs, only rurikawa connect is needed if the configuration stays the same.

Data created by the judger will be stored at ~/.rurikawa.
