  #
# Game build directory
# --------------------
  # Add your gamebuild directory to the env variable below.
  # The game build provided here needs to be integrated with server sdk for Amazon GameLift Servers.
ENV GAME_BUILD_DIRECTORY="<ADD_GAME_BUILD_DIRECTORY>" \
  #
# Game executable and launch parameters
# ---------------
  # Add the relative path to your executable in the 'GAME_EXECUTABLE' env variable below.
  # The game build provided over here needs to be integrated with server sdk for Amazon GameLift Servers.
  # This template assumes that the executable path is relative to the game build directory.
  # Add any launch parameters to pass into your executable in the 'LAUNCH_PARAMS' env variable below.
  # Add 'HOME_DIR' to identify where the game executable and logs exist.
GAME_EXECUTABLE="<ADD NAME OF EXECUTABLE WITHIN THE GAME DIRECTORY>" \
LAUNCH_PARAMS=<ADD LAUNCH PARAMETERS> \
HOME_DIR="/local/game" \


# Install dependencies as necessary
RUN yum install -y shadow-utils
    
RUN mkdir -p $HOME_DIR
COPY ./$GAME_BUILD_DIRECTORY/ $HOME_DIR
    
# Change directory to home
WORKDIR $HOME_DIR
    
# Set up for 'gamelift' user
RUN useradd -m gamelift && \
  echo "gamelift ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers && \
  chown -R gamelift:gamelift $HOME_DIR

# Add permissions to game build
RUN chmod +x ./$GAME_EXECUTABLE
    
USER gamelift
    
# Check directory before starting the container
RUN ls -lhrt .
    
# Check path before starting the container
RUN echo $PATH
    
# Start the game build
