# 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.
#
# The release should be accompanied by release notes in the notes/ subdirectory.
# These are published on coredns.io. For example see: notes/coredns-1.5.1.md
# Use make -f Makefile.release notes to create a skeleton notes document.
#
# For this to work properly you must fetch the tag of the previous release.
# Be sure to prune the PR list a bit, not everything is worthy!
#
# As seen in notes/coredns-1.5.1.md we want to style the notes in the following manner:
#
# * important changes at the top
# * people who committed/review code (the latter is harder to get)
# * Slightly abbreviated list of pull requests merged for this release.
#
# Steps to release, first:
#
# 1. Up the version in coremain/version.go
# 2. Do a make -f Makefile.doc # This has been automated in GitHub, so you can probably skip this step
# 3. go generate
# 4. Send PR to get this merged.
#
# Then:
#
# 1. Open an issue for this release
# 2. In an issue give the command: /release master VERSION
# Where VERSION is the version of the release - the release script double checks this with the
# actual CoreDNS version in coremain/version.go
# 3. (to test as release /release -t master VERSION can be used.
#
# See https://github.com/coredns/release for documentation README on what needs to be setup for this to be
# automated (can still be done by hand if needed). Especially what environment variables need to be
# set! This further depends on Caddy being setup and [dreck](https://github.com/miekg/dreck) running as a plugin in Caddy.
#
# To release we run, these target from the this Makefile.release ordered like:
# * make release
# * make github-push
#
# Testing this is hard-ish as you don't want to accidentally release a coredns. If not executing the github-push target
# you should be fine.
# Docker image creation and upload are now separate steps, because it often failed before. See the Makefile.docker for
# details.
