# This image will be published as dspace/dspace
# See https://github.com/DSpace/DSpace/tree/main/dspace/src/main/docker for usage details
#
# - note: default tag for branch: dspace/dspace: dspace/dspace:latest-test
#
# This image is meant for TESTING/DEVELOPMENT ONLY as it deploys the old v6 REST API under HTTP (not HTTPS)

# This Dockerfile uses JDK11 by default, but has also been tested with JDK17.
# To build with JDK17, use "--build-arg JDK_VERSION=17"
ARG JDK_VERSION=11
ARG DSPACE_VERSION=latest

# Step 1 - Run Maven Build
FROM dspace/dspace-dependencies:${DSPACE_VERSION} as build
ARG TARGET_DIR=dspace-installer
WORKDIR /app
# The dspace-installer directory will be written to /install
RUN mkdir /install \
    && chown -Rv dspace: /install \
    && chown -Rv dspace: /app
USER dspace
# Copy the DSpace source code (from local machine) into the workdir (excluding .dockerignore contents)
ADD --chown=dspace . /app/
# Build DSpace (INCLUDING the optional, deprecated "dspace-rest" webapp)
# Copy the dspace-installer directory to /install.  Clean up the build to keep the docker image small

  mv /app/dspace/target/${TARGET_DIR}/* /install && \

# Step 2 - Run Ant Deploy

# Link the DSpace 'server' webapp into Tomcat's webapps directory.
