Godot's headless --import/--export-release refuses to auto-detect Blender for .blend import: "Blender path is invalid or not set... Cannot configure blender path in headless mode" (modules/gltf/editor/editor_scene_importer_blend.cpp). Without this, the image's Blender install was silently unusable for its one job — no .blend file would ever import in CI. Bakes filesystem/import/blender/blender_path into a per-minor-version EditorSettings .tres, same pattern barichello/godot-ci and abarichello's own Dockerfile use for Android SDK/JDK paths. Found and verified while resolving ticket #9 (Merge, publish, and validate the debian-slim image end-to-end): confirmed a .blend import produces a real .scn with this fix, and fails without it, on a real container built from this Dockerfile.

# GODOT_VERSION is a stable Godot release tag (e.g. "4.7.1", no "-stable" suffix — Godot 4.0+
|
|
# only, see docs/handoff/godot-ci-custom-image.md). BLENDER_URL is the tarball to bake in.
|
|
# .gitea/workflows/publish.yml always resolves both at build time via
|
|
# scripts/resolve-godot-version.sh and scripts/resolve-blender-url.sh. The defaults below are
|
|
# only a fallback for a plain local `docker build`.
|
|
#
|
|
# Godot itself is downloaded straight from its official GitHub releases (godot-builds), the same
|
|
# source barichello/godot-ci's own Dockerfile uses — this image no longer depends on that image
|
|
# as a base. Decided via wayfinder map https://git.arthurerlich.de/haylan/godot-ci/issues/2,
|
|
# ticket https://git.arthurerlich.de/haylan/godot-ci/issues/7: Alpine was considered and rejected
|
|
# (official Godot/Blender binaries are glibc-only, and Alpine's musl-native alternatives live
|
|
# only on its unpinned `edge` repo); a plain glibc-slim base doesn't cost the compatibility risk.
