# panel-native 7 Days to Die runtime image.
|
|
#
|
|
# Unlike third-party images (vinanrra/LGSM, didstopia, etc.), this image does
|
|
# ONE thing: run a 7DTD dedicated server. Download + validate is handled by
|
|
# the panel's SteamCMD updater sidecar, which writes into the same Docker
|
|
# volume we mount read/write here. No LGSM, no tmux, no GitHub-fetch on
|
|
# start, no backup-before-start "surprises" — just the game.
|
|
#
|
|
# Expected runtime layout inside the container:
|
|
# /game — SteamCMD-installed 7DTD binaries (panel volume)
|
|
# /game-saves — save + config data (panel volume)
|
|
# /entrypoint.sh — this image's entrypoint (renders serverconfig.xml and
|
|
# execs the game with stdout/stderr unbuffered)
