Eric Chiang ee27a4f9f4 *: only use docker when releasing, update to Go 1.8, remove aci scripts

This change modifies our release process to only require Docker
when building a release and updates our released binary to use Go
1.8. It also removes our .aci scripts, which we've not been
regularly building.

A nice consequence is that OSX users can now build a release image.

Releases

Making a dex release involves:

Tagging a git commit and pushing the tag to GitHub.
Building and pushing a Docker image.

This requires the following tools.

Docker

And the following permissions.

Push access to the github.com/coreos/dex git repo.
Push access to the quay.io/coreos/dex Docker repo.

Tagging the release

Make sure you've uploaded your GPG key and configured git to use that signing key either globally or for the Dex repo. Note that the email the key is issued for must be the email you use for git.

git config [--global] user.signingkey "{{ GPG key ID }}"
git config [--global] user.email "{{ Email associated with key }}"

Create a signed tag at the commit you wish to release. This action will prompt you to enter a tag message, which can just be the release version.

git tag -s v2.0.0 ea4c04fde83bd6c48f4d43862c406deb4ea9dba2

Push that tag to the CoreOS repo.

git push git@github.com:coreos/dex.git v2.0.0

Draft releases on GitHub and summarize the changes since the last release. See previous releases for the expected format.

https://github.com/coreos/dex/releases

Minor releases - create a branch

If the release is a minor release (2.1.0, 2.2.0, etc.) create a branch for future patch releases.

git checkout -b v2.1.x tags/v2.1.0
git push git@github.com:coreos/dex.git v2.1.x

Patch releases - cherry pick required commits

If the release is a patch release (2.0.1, 2.0.2, etc.) checkout the desired release branch and cherry pick specific commits. A patch release is only meant for urgent bug or security fixes.

RELEASE_BRANCH="v2.0.x"
git checkout $RELEASE_BRANCH
git checkout -b "cherry-picked-change"
git cherry-pick (SHA of change)
git push origin "cherry-picked-change"

Open a PR onto $RELEASE_BRANCH to get the changes approved.

Building the Docker image

Build the Docker image and push to Quay.

# checkout the tag
git checkout tags/v2.1.0
# will prompt for sudo password
make docker-image
sudo docker push quay.io/coreos/dex:v2.1.0
