	#!/bin/bash
	#
	# Run the init-hbp-solr-home script and source any '.sh' scripts that are found
	# in `/docker-entrypoint-initdb.d`. Files there will be executed in alphabetical
	# order.
	#
	# This script (run-initdb) is sourced by some of the solr-* commands, so that
	# I can run eg:
	#
	# mkdir initdb; echo "echo hi" > initdb/hi.sh
	# docker run -v $PWD/initdb:/docker-entrypoint-initdb.d hbp-lucene-solr
	#
	# and have your script execute before hbp-lucene-solr instance starts.
	#
	# Note: scripts can modify the environment, which will affect subsequent scripts
	# and ultimately Solr. That allows you to set environment variables from your
	# scripts (though you usually just use "docker run -e"). If this is undesirable
	# in your use-case, have your scripts execute a sub-shell.

	set -e
