# Makefile for creating and uploading CoreDNS docker image.
|
|
#
|
|
# First you should do a release and then call this Makefile to create and upload
|
|
# the image.
|
|
#
|
|
# 1. Reuse the issue for this release
|
|
# 2. In an issue give the command: /docker VERSION
|
|
# Where VERSION is the version of the release.
|
|
# 3. (to test as release /docker -t VERSION can be used.
|
|
#
|
|
# To release we run, these target from the this Makefile.docker ordered like:
|
|
# * make release
|
|
# * make docker-push
|
|
#
|
|
# Testing docker is done e.g. via:
|
|
#
|
|
# export DOCKER_PASSWORD=<pass>
|
|
# export DOCKER_LOGIN=miek
|
|
# make VERSION=x.y.z DOCKER=miek -f Makefile.docker release docker-push
