# First ONLY copy and install the requirements, so that changes outside
# `requirements.txt` don't force a re-install of all dependencies.
#
# Note that this will install the Reboot library and CLI.
COPY requirements.lock requirements.txt
RUN pip install -r requirements.txt

# Next, copy the API definition and generate Reboot code. This step is also
# separate so it is only repeated if the `api/` code changes.
COPY api/ api/
COPY .rbtrc .rbtrc

# Run the Reboot code generators. We did copy all of `api/`, possibly
# including generated code, but it's not certain that `rbt protoc` was run in
# that folder before this build was started.
RUN rbt protoc

# Now copy the rest of the source code.
COPY backend/src/ backend/src/

# Running the application requires that we set the PYTHONPATH correctly.
# TODO: Update to use `rbt serve`.
