Istio Release

This repository defines the release process for Istio.

The release process is split into two phases, the build and publish

Build

The build step will pull down all needed sources to build a release. Generally this is from GitHub, but local files can be used as well for private builds or local testing.

Next, it will build a variety of different artifacts, including a manifest.yaml which defines what dependencies were a part of the build.

While not completely possible today, the goal is for the build process to be runnable in an air gapped environment once all dependencies have been downloaded.

Publish

The publish step takes in the build artifacts as an input, and publishes them to a variety of places:

• Copy artifacts to GCS
• Push docker images
• Tag all Github source repositories
• Publish a Github release

All of these steps can be done in isolation. For example, a daily build will first publish to a staging GCS and dockerhub, then once testing has completed publish again to all locations.

Credentials

The following credentials are needed

• Github token as environment variable GITHUB_TOKEN.
• Docker credentials (TODO - how to set these).
• GCP credentials for GCS (TODO - how to set these).
