coredns/Makefile.release

# Makefile for releasing CoreDNS
#
# The release is controlled from coremain/version.go. The version found there is
# used to tag the git repo and to build the assets that are uploaded to github
# (after some sanity checks).
#
# The release should be accompanied by release notes published on coredns.io.
# For example: https://coredns.io/2016/09/18/coredns-001-release/ Also send an
# email to coredns-discuss@ to announce the new version.
#
# We use https://github.com/progrium/gh-release to automate github stuff be sure
# to have that binary in your path.
#
# Get a list of authors for this release with:
#
# git log --pretty=format:'%an' v001..master | sort -u (where v001 is the
# previous release, obviously you'll need to adjust this)
#
# Steps:
#
# * Get an access token: https://help.github.com/articles/creating-an-access-token-for-command-line-use/
# * export GITHUB_ACCESS_TOKEN=<token>
# * Up the version in coremain/version.go
# * Run: make -f Makefile.release release
#   * will *commit* your change with 'Release $VERSION'
#   * push to github
#   * build the release and do all that fluff.
#
# Steps for docker:
#
# * Login into docker: docker login (should have push creds for coredns registry)
# * We use the manifest-tool from https://github.com/estesp/manifest-tool to build the manifest list
# * Make sure you have the binary in your path.
#
# * Run: make -f Makefile.release docker
#
# Docker push should happen after you make the new release and uploaded it to
# Github.
