# Kandev Server Dockerfile
#
# Single-stage build that consumes prebuilt artifacts. The release workflow
# (.github/workflows/release.yml) extracts the per-arch release bundle
# (`kandev-linux-{x64,arm64}.tar.gz`) into the build context, then this file
# just COPYs the native binaries into the runtime layout.
#
# Building this file outside CI (manual `docker build .`) will fail because
# the `bundle/` directory isn't present in the build context. To build
# locally, extract a release tarball into ./ctx/bundle/ alongside
# ./ctx/docker-entrypoint.sh and run:
#   docker build -f Dockerfile ./ctx
#
# Run:
#   docker run -p 38429:38429 -v kandev-data:/data ghcr.io/kdlbs/kandev:latest
