Using Google Cloud's Buildpacks with GCB

This project demonstrates how to use a cloudbuild.yamlto build an app usingGoogle Cloud's Buildpacks. This example will demonstrate how to take advantage of the --cache-image mechanism to minimise build times.

How to use

You'll be using the following GCP APIs:

  • Cloud Build
  • Artifact Registry

You'll also need to have the gcloud CLI installed

  1. Open cloudbuild.yaml
  2. Update line 10 with your app image repository name and location
  3. Update line 14 with your cache image respository name and location
  4. In your terminal, run gcloud builds submit

How this works

  • The provided cloudbuild.yaml has a single step that utilizes the gcr.io/k8s-skaffold/pack image. This is an image maintained by the Skaffold team and provides the Cloud Native Buildpacks pack CLI
  • We'll be following the instructions on using --cache-image mechanism to build
    • an app image (line 10)
    • a cache image (line 14)
  • First run of this will be relatively slow, generating both the app image and the cache image
  • Subsequent runs will take advantage of the cache image to speed up build times
