Dockerfile

# 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:dspace-7_x

# 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
# The Docker version tag to build from
ARG DSPACE_VERSION=dspace-7_x
# The Docker registry to use for DSpace images. Defaults to "docker.io"
# NOTE: non-DSpace images are hardcoded to use "docker.io" and are not impacted by this build argument
ARG DOCKER_REGISTRY=docker.io

# Step 1 - Run Maven Build
FROM ${DOCKER_REGISTRY}/dspace/dspace-dependencies:${DSPACE_VERSION} AS build
ARG TARGET_DIR=dspace-installer
WORKDIR /app
# The dspace-installer directory will be written to /install

ADD --chown=dspace . /app/
# Build DSpace (note: this build doesn't include the optional, deprecated "dspace-rest" webapp)
# Copy the dspace-installer directory to /install.  Clean up the build to keep the docker image small
# Maven flags here ensure that we skip building test environment and skip all code verification checks.
# These flags speed up this compilation as much as reasonably possible.

# Step 3 - Run tomcat

# Please note that server webapp should only run on one path at a time.
