# Build the etcd image
#
# Usage:
# [TAGS=2.2.1 2.3.7 3.0.17 3.1.10] [REGISTRY=gcr.io/google_containers] [ARCH=amd64] [BASEIMAGE=busybox] make (build|push)
# The image contains different etcd versions to simplify
# upgrades. Thus be careful when removing any tag from here.
#
# NOTE: The etcd upgrade rules are that you can upgrade only 1 minor
# version at a time, and patch release don't matter.
#
# Except from etcd-$(tag) and etcdctl-$(tag) binaries, we also
# need etcd and etcdctl binaries for backward compatibility reasons.
# That binary will be set to the last tag from $(TAGS).
