Publish moved off the host docker socket to a rootless SSH forced-command on Lucy (#444), so the docker CLI in the build image is now unused. Keep openssh-client (the publish step ssh's the signed APK to the host).

# Sulkta straw-build — reproducible Android + Rust build image for the Straw APK.
|
|
#
|
|
# Pushed to git.sulkta.com/sulkta-infra/straw-build:latest and used as the job
|
|
# `container:` in .forgejo/workflows/build.yml. It bakes the toolchain that
|
|
# otherwise lives only in bind-mounts on the long-running crafting-table, so a
|
|
# FRESH Forgejo CI job container is fully self-contained (no host /caches
|
|
# dependency, no per-machine signing key).
|
|
#
|
|
# Toolchain pinned to exactly what builds successfully:
|
|
# JDK 21 · NDK 27.2.12479018 · build-tools 34.0.0 + 36.0.0 · platforms android-36
|
|
# Rust stable + 4 Android targets · cargo-ndk · clang/libclang (rquickjs bindgen)
|
|
# AGP 9.2.1 (compileSdk 36) requires build-tools 36; we pre-install it so the build
|
|
# doesn't sdkmanager-download it on every run (older images shipped only 34.0.0 and
|
|
# AGP auto-fetched 36 at build time — works, but a per-build network dependency).
|
|
# 34.0.0 is kept for belt-and-suspenders; apksigner uses the highest present (36).
