# This is a multi stage build.

# The gdal_builder image/stage can be enabled by using
# `--build-arg BUILD_GDAL=true`. The gdal_builder is derived
# from the osgeo/gdal Dockerfile (small ubuntu) and simplified
# version activating the JAVA features on top.
# It builds gdal from sources, which is necessary to get
# working gdal JAVA Bindings, e.g. for the geoserver gdal extension.
# see https://trac.osgeo.org/osgeolive/ticket/2288
#
# NOTE: the build process can take up to 15 mins on average hardware!
