Tiny judge server. docker based.

Master: Develop:

akapen is judge server for competitive programming. Every judges run on secure docker container.

just type 4 commands.

git clone https://github.com/kekeho/akapen
cd akapen
docker-compose build  # build akapen
sh build-worker.sh  # build worker containers

docker-compose up

then, boot all system include redis(port: 6379) and akapen.

Throw task json like ↓ into redis compile_queue list.

{
    "user": {
        "id": "abc1234"
    },
    "uuid": "e8411f06-c3db-436b-8d57-7af03c962b5f",
    "language": "python3",
    "code": "print(input())",
    "input": "abcdef",
    "assert": "abcdef\n",
    "memory": "1M",
    "time": "1000000000"
}

Judge results will appear on redis results list.

{
    "user": {
        "id": "abc1234"
    },
    "uuid": "e8411f06-c3db-436b-8d57-7af03c962b5f",
    "language": "python3",
    "code": "print(input())",
    "input": "abcdef",
    "assertion": "abcdef\n",
    "memory": "1M",
    "time": "1000000000",
    "status": "AC",
    "output": "abcdef\n",
    "stderr": "",
    "exec_time": "432427451"
}

Now, just supported only AC, WA, RE, TLE, Compiled, JSE

Now, just supported only python3.

• python3 version: 3.7.3 dockerfile: compile | run

• CPU limit
  1 judge container can use single core, 5% of all (cpu-period=100000, cpu-quota=5000)
• Offline
• PIDs limit
  10 (anti fork-bomb)
• Time info
  exec_time gets from docker inspect (StartedAt, FinishedAt)
  In akapen, the unit of time is nanoseconds

docker-compose run judge nimble test
