API Client generation

The Update API client is automatically generated based on the API discovery functionality provided by the endpoints library. This document describes how to update updateservicectl to reflect changes in the API.

Most of the work is done by the Makefile. Before it can be run though, a couple of things have to be set up. First, stand up an instance of CoreUpdate with the API you want to generate the bindings for. Then, make sure you have the google-api-go-generator tool installed. Get it with the following command -

go get google.golang.org/api/google-api-go-generator

Once the environment is set up, simply run this make command -

make api-gen

and the bindings should be updated. Check its work, commit all the binding changes into a single, separate commit, and then update the necessary function calls to use the new bindings (if necessary).
