# Builds the Druid image for testing. Does not include dependent
# tools such as MySQL, Zookeeper or Kafka: those reside in their own images.
#
# The script assumes that Maven as placed a Druid distribution and the
# required extra jars in the same location as this file: in the target/docker
# directory. You must run Maven once to populate these files after each
# build. After that first image build, you can use rebuild.sh to do follow-on
# image builds.

# This Dockerfile prefers to use the COPY command over ADD.
# See: https://phoenixnap.com/kb/docker-add-vs-copy

ARG JDK_VERSION=8-slim-buster

# The FROM image provides Java on top of Debian, and
# thus provides bash, apt-get, etc.
