# Now, typically, we want to order our COPY commands such that
# things that change most often are copied in last, so
# that we can benefit from layer caching.
# However, since meet-data is so disproportionately large,
# we COPY it in FIRST and anytime we change anything else,
# layer caching will still have this cached and will bust
# later when there's probably less than a MB left to COPY in.

# So, we'll
# COPY in data from heaviest to lightest
COPY meet-data meet-data/
COPY lifter-data lifter-data/
COPY project-data project-data/

# COPY in build instructions which shouldn't change as often as the...
COPY Cargo.* ./
COPY Makefile ./

# project code
COPY .git .git/
COPY checker checker/
COPY crates crates/
COPY goodlift-import goodlift-import/
COPY server server/
COPY tests tests/

# Build it
