I'm unsure at this time if this will be a pattern we want to adopt elsewhere? But it seems to work well here. It uses a two-part build process:
FROM python:3.13-slim AS builderestablishes the first build layer- We generate a
requirements.txtfile from the project'spyproject.tomlanduv.lockfiles - We start a new layer
FROM python:3.13-slim(the final layer) - We use
COPY --from=builder /requirements.txt /requirements.txtto get that importantrequirements.txtfile, but that's the only asset from the previous layer - We use the global python environment and install dependencies
- We launch the click CLI in a pretty boring way, no
uvscripts involved
