# Debian package Makefile
#
# Dependencies:  git debhelper build-essential autotools-dev devscripts golang
# Notes:
# Use 'make debian' to create the debian package
# To create a specific version, use 'VERSION_TAG=v0.2.0 make debian'
# GPG_KEY environment variable needs to contain a GPG private key for package
# to be signed and uploaded to debian.
# If GPG_KEY is not defined, make debian will create docker package and exit
# with status code 2
