Run builds across all machine types in Cloud Build to find the optimal price/performance tradeoff

Cloud Build Optimizer

This tool allows you to quickly run your Cloud Build configuration against multiple machine types in parallel.

Once the jobs are complete you get a read out of the time each took and how much they cost.

Quick Start

This repo includes and example cloudbuild.yaml that compiles the Linux kernel. Below are the steps to test out that configuration across the available Cloud Build machine types.

1. Clone this repo and change directories to the example folder:

   git clone https://github.com/viglesiasce/cloudbuild-optimizer
   cd cloudbuild-optimizer/example

2. Download the latest release:

   curl -L https://github.com/viglesiasce/cloudbuild-optimizer/releases/download/v0.2.0/cloudbuild-optimizer_0.2.0_$(uname)_$(uname -m) -o cloudbuild-optimizer
   chmod +x cloudbuild-optimizer

3. Run the tool.

   $ ./cloudbuild-optmizer

   You should see output as follows:
