How to use brutal tester

Dockerised so non-Java users can easily build it

And image trading can be easier when using a common container registry

1. Docker build

docker build -t codingame-brutaltester-spring-2023 .

2. Run

docker run --name brutaltester --rm \
        -v /var/run/docker.sock:/var/run/docker.sock \ # Required so brutaltester container can docker run itself
        -v ~/.docker/config.json:/root/.docker/config.json \ # Optional : may need this so docker can have same credentials as host, and pull on private registries
        -v /var/log/brutaltester:/var/log/brutaltester \ # Optional : this way you can retrive logs on your local filesystem
        codingame-brutaltester-spring-2023
        -p1 "first-player-container-name"  # container name for first player
        -p2 "second-player-container-name" # container name for second player
        -lvl 4 # League level : see below (4 is default value)
        -n 100 # For example : Number of games to play. Any other usual brutaltester options can be used

League levels

  • 1 = Wood 2 : Single base, no eggs, no attacking
  • 2 = Wood 1 : Eggs appears
  • 3 = Bronze : Multiple bases, attacks enabled
  • 4 = Silver+ : Score in inputs

3. Sample Player Dockerfile (Java)

For a Java player, sample Dockerfile to convert an "Output.java" to container (change path to your needs) :

FROM eclipse-temurin:11-jdk-alpine AS build

WORKDIR /app
COPY ./Output.java ./
RUN javac Output.java

FROM eclipse-temurin:11-jre-alpine

WORKDIR /app
COPY --from=build ./app/*.class ./

ENTRYPOINT [ "java", "Player" ]

Can be built with

docker build -t my-codingame-2023:latest .

Same kind of dockerfile can easily be created for other languages
