Cloud Native Buildpacks CI

This repository contains configuration for our CI deployment, at ci.buildpacks.io.

Using assets generated by the pipeline

We generate versioned lifecycle binaries for each commit (GCP account login required). You can also get a listing of binaries, without needing to login, by using gsutil:

$ gsutil ls -al gs://cloud-native-buildpacks-lifecycle-binaries/development/

We also provide a "latest" file to ease consumption by other automated systems, which can be directly accessed via HTTPS:

https://storage.googleapis.com/cloud-native-buildpacks-lifecycle-binaries/development/lifecycle-binaries-latest.tgz

https://storage.googleapis.com/cloud-native-buildpacks-lifecycle-binaries/release/lifecycle-binaries-latest.tgz

This file is updated after each successful acceptance test of the lifecycle.

To see and retrieve older versions of lifecycle-binaries-latest.tgz, you can use gsutil:

$ gsutil ls -al gs://cloud-native-buildpacks-lifecycle-binaries/development/lifecycle-binaries-latest.tgz

Concourse

If you are using Concourse, here are the YAML snippets you need:

resource_types:
- name: gcs-resource
  type: docker-image
  source:
    repository: frodenas/gcs-resource

resources:
- name: latest-lifecycle-archive-dev
  type: gcs-resource
  source:
    bucket: cloud-native-buildpacks-lifecycle-binaries
    # A GCP service account token with "Storage Legacy Bucket Viewer" and "Storage Object Viewer"
    json_key: ((concourse-service-account-key-json))
    versioned_file: development/lifecycle-binaries-latest.tgz

jobs:
- name: jobbityjob
  plan:
  - get: latest-lifecycle-archive-dev

Contents

The lifecycle-binaries-latest.tgz archive contains:

  • Lifecycle binaries without versions appended to their name, and
  • A VERSION file.

For each file we zero out the mtime, user and group values to improve reproducibility.

You can’t perform that action at this time.
