start-server.sh (1)
72-72: Consider using unquoted expansion for better multi-flag support.The current quoted expansion
"${ADDITIONALFLAGS}"has two limitations:
Empty string argument: When
ADDITIONALFLAGS=""(the default), the command receives an empty string as an argument rather than no argument, which may be passed toSCUMServer.exeunnecessarily.Single-argument limitation: Multiple flags like
ADDITIONALFLAGS="-flag1 -flag2"would be passed as a single argument"-flag1 -flag2"instead of two separate arguments.Using unquoted expansion would resolve both issues: empty values would expand to nothing (no argument added), and multiple flags would be split via word splitting.
🔎 Proposed fix
-port=${GAMEPORT:-7777} \ -QueryPort=${QUERYPORT:-27015} \ -MaxPlayers=${MAXPLAYERS:-32} \ - "${ADDITIONALFLAGS}" & + ${ADDITIONALFLAGS} &Security note: Unquoted expansion enables shell expansion and word splitting, but the security risk is acceptable here since
ADDITIONALFLAGSis controlled by the server administrator throughdocker-compose.yml.

Learning: In the EvilOlaf/scum repository, providing detailed help with customizing the gaming experience (such as extensive SCUM server configuration guidance) is out of scope. The repository focuses on the Docker container setup rather than comprehensive game server customization documentation.

docker-compose.yml (1)
10-10: LGTM!The environment variable definition follows the established pattern and provides a reasonable default.
README.md (1)
68-71: LGTM!Clear documentation with a practical example. The YAML syntax is correct and the FAQ placement is logical.

Allows setting various parameters which will be passed on to
SCUMserver.exelike-nobattleyeto disable anti-cheat.In future there may be further switches or parameters introduced upstream so this also hardens the overall setup for the future.
