The lobby image had never been built and two defects blocked it: the felis image .dockerignore excluded plugins/* and only re-included limbo/shared, so the lobby Dockerfile's COPY plugins/paper landed empty; and the plugin stage used eclipse-temurin:21-jdk, which ships no gradle (and the tree vendors no wrapper), failing with 'gradle: not found'. Re-include plugins/paper and build the paper plugin on gradle:8.14-jdk21, matching the limbo image. Verified: both images build and boot (limbo /healthz 200 on 25565; lobby reaches 'Done' with felis-paper enabled).

# Felis lobby image: Paper + the felis-paper /menu plugin.
|
|
#
|
|
# CODE-ONLY in this repo — not built by the Go CI. It packages the always-on
|
|
# "lobby" hub the setup provisioner points [velocity] lobby_image at. The lobby is
|
|
# the POST-auth /menu hub: it is reached only when the login gate transfers an
|
|
# authenticated player onward, and it must never be a fallback target.
|
|
#
|
|
# Build:
|
|
# docker build -f deploy/lobby/Dockerfile \
|
|
# --build-arg PAPER_JAR_URL=https://<mirror>/paper-1.21.x-<build>.jar \
|
|
# -t felis-lobby:demo .
|
|
# docker save felis-lobby:demo | sudo k3s ctr images import -
|
|
# # felis.toml → [velocity] lobby_image = "felis-lobby:demo"
|
|
#
|
|
# Contract: the game server listens on 25565 (the CRD GamePort). The lobby speaks
|
|
# only the felis:control plugin-message channel (spec §12) — it holds no felis-api
|
|
# token.
|
|
|
|
# ---- build the felis-paper plugin jar (Paper API is Java 21) ----
|
|
# gradle:8.14-jdk21 — an official Gradle image on JDK 21 (this tree vendors no Gradle
|
|
# wrapper, and a bare JDK image ships no `gradle`). JDK 21 matches the Paper API.
