+# Releases
+
+Making a dex release involves:
+
+* Tagging a git commit and pushing the tag to GitHub.
+* Building and pushing a Docker image.
+* Building, signing, and hosting an ACI.
+
+This requires the following tools.
+
+* rkt
+* Docker
+* [docker2aci](https://github.com/appc/docker2aci)
+* [acbuild](https://github.com/containers/build) (must be in your sudo user's PATH)
+
+And the following permissions.
+
+* Push access to the github.com/coreos/dex git repo.
+* Push access to the quay.io/coreos/dex Docker repo.
+* Access to the CoreOS application signing key.
+
+## Tagging the release
+
+Make sure you've [uploaded your GPG key](https://github.com/settings/keys) and
+configured git to [use that signing key](
+https://git-scm.com/book/en/v2/Git-Tools-Signing-Your-Work) 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 v2.1.0-alpha ea4c04fde83bd6c48f4d43862c406deb4ea9dba2
+```
+
+Push that tag to the CoreOS repo.
+
+```
+git push git@github.com:coreos/dex.git v2.1.0-alpha
+```
+
+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
+
+## Building the Docker image
+
+Build the Docker image and push to Quay.
+
+```bash
+# checkout the tag
+git checkout tags/v2.1.0-alpha
+# rkt doesn't play nice with SELinux, see https://github.com/coreos/rkt/issues/1727
+sudo setenforce Permissive
+# will prompt for sudo password
+make docker-image
+sudo docker push quay.io/coreos/dex:v2.1.0-alpha
+```
+
+## Building the ACI
+
+```bash
+# checkout the tag
+git checkout tags/v2.1.0-alpha
+# rkt doesn't play nice with SELinux, see https://github.com/coreos/rkt/issues/1727
+sudo setenforce Permissive
+# will prompt for sudo password
+make aci
+# aci will be built at _output/image/dex.aci
+```
+
+Sign the ACI using the CoreOS application signing key. Upload the ACI and
+signature to the GitHub release.
