Bazel rules for apko

Wraps the https://github.com/chainguard-dev/apko tool for use under Bazel.

Need help? This ruleset has support provided by https://aspect.dev.

Installation

Follow instructions in the release notes from the release you wish to use. Be sure to follow the "Initial Setup" instructions as well. https://github.com/chainguard-dev/rules_apko/releases

To use a commit rather than a release, you can point at any SHA of the repo, using the GitHub-provided source archive like `https://github.com/chainguard-dev/rules_apko/archive/abc123.tar.gz``

Note

Note that GitHub source archives don't have a strong guarantee on the sha256 stability. See https://github.blog/2023-02-21-update-on-the-future-stability-of-source-code-archives-and-hashes/

Usage

Apko usage begins with an apko.yaml configuration file. The apko resolve tool will create a corresponding apko.resolved.json file, and this is where Bazel will read to fetch external content.

First you import these base layers into Bazel:

  • With Bazel 6 and [bzlmod], call apk.translate_lock in MODULE.bazel
  • Otherwise, call translate_apko_lock in WORKSPACE

Then, call apko resolve path/to/apko.yaml to generate apko.resolved.json and use the apko_image rule to build the image, producing an OCI format output.

Finally, we recommend using https://github.com/bazel-contrib/rules_oci as the next step in your Bazel build to add application code from your repo as the next layers of the image.

See the examples folder in this repository, which relies on base layers declared in /MODULE.bazel.

Also see the e2e folder in this repository, where we declare our end-to-end test.

Public API

  • translate_lock Repository rules for translating apko.resolved.json
  • rules Build OCI images from APK packages directly without Dockerfile
