# Build the etcd image
#
# Usage:
# [BUNDLED_ETCD_VERSIONS=2.2.1 2.3.7 3.0.17 3.1.12 3.2.24] [REGISTRY=k8s.gcr.io] [ARCH=amd64] [BASEIMAGE=busybox] make (build|push)
#
# The image contains different etcd versions to simplify
# upgrades. Thus be careful when removing any versions 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-$(version) and etcdctl-$(version) binaries, we also
# need etcd and etcdctl binaries for backward compatibility reasons.
# That binary will be set to the last version from $(BUNDLED_ETCD_VERSIONS).
BUNDLED_ETCD_VERSIONS?=2.2.1 2.3.7 3.0.17 3.1.12 3.2.24
# LATEST_ETCD_VERSION identifies the most recent etcd version available.
LATEST_ETCD_VERSION?=3.2.24
# REVISION provides a version number fo this image and all it's bundled
# artifacts. It should start at zero for each LATEST_ETCD_VERSION and increment
# for each revision of this image at that etcd version.
REVISION?=1
# IMAGE_TAG Uniquely identifies k8s.gcr.io/etcd docker image with a tag of the form "<etcd-version>-<revision>".
