# Build the etcd image

|
|
# Usage:
|
|
# [BUNDLED_ETCD_VERSIONS=2.2.1 2.3.7 3.0.17 3.1.12 3.2.18] [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).
