# The default deploy instructions (https://biffweb.com/docs/reference/production/) don't
# use Docker, but this file is provided in case you'd like to deploy with containers.
#
# When running the container, make sure you set any environment variables defined in config.env,
# e.g. using whatever tools your deployment platform provides for setting environment variables.
#
# Run these commands to test this file locally:
#
#   docker build -t your-app .
#   docker run --rm -e BIFF_PROFILE=dev -v $PWD/config.env:/app/config.env your-app

# This is the base builder image, construct the jar file in this one
# it uses alpine for a small image
FROM clojure:temurin-21-tools-deps-alpine AS jre-build

# Install the missing packages and applications in a single layer
RUN apk add curl rlwrap

WORKDIR /app
COPY deps.edn ./
RUN clj -P
COPY build.clj config.edn ./
COPY src ./src

# construct the application jar
RUN clj -T:build uber  && cp target/snippets-standalone.jar ./app.jar && rm -r target

# This stage (see multi-stage builds) is a bare Java container
# copy over the uberjar from the builder image and run the application
