# 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
# blog.coredns.io. For example:
# https://blog.coredns.io/2016/09/18/coredns-001-release/
#
# We use https://github.com/progrium/gh-release to automate github stuff
# be sure to have that binary in your path.
#
# 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
# * Commit
# * Run: make -f Makefile.release
