Waypoint Plugin Google Cloud Functions

waypoint-plugin-cloudfunctions is a deploy (registry, platform & release) plugin for Waypoint. It allows you to stage previously built zip artifcats to Google Cloud Functions and then release the staged deployment and open it to general traffic.

Status

I am currently using this plugin to deploy several Google Cloud Functions in production. It is working fine as far as my use case goes. Please open an issue for feedback, issues or feature requests.

Current Limitation

The plugin doesn't support staging deployments before releasing them to general traffic, this is mainly because I haven't found a way to support this using Cloud Functions. This means that the plugin does almost nothing in the release stage expect setting the IAM policy for unauthenticated functions.
Destroy is not supported for build nor release for the same reason mentioned above. The only way I was able to implement this was by deleting the function, which is not what most people would want I think.

Install

To install the plugin, run the following command:

# First install the plugin archive by following the instuction here: https://github.com/sharkyze/waypoint-plugin-archive
