Dockerfile

# --- Multi-stage Docker build ---
# 1. Build runtime environment (see runtime/README.md)
# 2. Compile better-sqlite3 module
# 3. Run unit tests to confirm everything is ok
# 4. Produce a minimally sized image for distribution

# 1. ------------------------------------------------
FROM pelias/spatial:runtime_ubuntu_bionic as runtime

# 2. ------------------------------------------------
FROM pelias/baseimage as better_sqlite3

# we require clang++ for compiling better-sqlite3
# this adds ~400MB to the image, so we build in a
# separate image and only copy the files we need.
