Until now `docker compose up` built the image on the user's machine: a compiler toolchain, every dev dependency, a few minutes of CPU — on a Raspberry Pi considerably more. The compose files now pull ghcr.io/tillheidrich/klarbild:1, built by .github/workflows/image.yml for linux/amd64 and linux/arm64. `:1` follows every 1.x release, so an update is `docker compose pull && docker compose up -d`. `build: .` is one commented line away for anyone who prefers to build. The Dockerfile has two stages now. The runtime stage carries the built server, production dependencies and the migrations — no compiler, no dev dependencies, no source tree. argon2 and sharp ship prebuilt binaries for both architectures, so python/make/g++ are gone entirely. It runs as the `node` user (uid 1000); a fresh named volume at /data inherits that ownership. Verified locally: image builds, boots against Postgres, applies all 17 migrations, prints the first-run password, passes its healthcheck, accepts an upload as the unprivileged user and returns an A4 sheet that measures 210.00 x 297.00 mm.
