Assemble minimal OCI images from declarative package configs with apko
SkillCloud & infraThis skill adds the ability to build minimal OCI images, the standard image format used by container tools, from declarative package configs. Instead of following a conventional Dockerfile flow, the AI works from a simple manifest that lists the packages an image should contain. The result is a small image whose contents are easy to review, which helps when supply-chain clarity matters.
Available today. Use it from your connected AI after setup.
No other account needed.
Describe the packages you want in your image and ask the AI to write the manifest and build the image from it. Then check the resulting image contents to confirm only what you listed is included.
Then ask your AI: use the Assemble minimal OCI images from declarative package configs with apko skill
What your AI can do with it
- Build small OCI images from declarative package manifests
- Define image contents in a readable package config instead of a Dockerfile
- Keep images limited to the exact packages listed in the manifest
- Review what went into an image to support supply-chain clarity

The instructions your AI receives, as published by agentskillexchange/skills in skills/assemble-minimal-oci-images-from-declarative-package-configs-with-apko/SKILL.md and read by ahel’s review.
Use apko to build small OCI images from declarative package manifests when supply-chain clarity and minimal contents matter more than a conventional Dockerfile flow.
Prerequisites
apko and access to the package sources and OCI output destination you intend to use
Installation
Use the upstream install or setup path that matches your environment:
- brew install apko
- go install chainguard.dev/apko@latest
- docker run cgr.dev/chainguard/apko version
- docker run -v "$PWD":/work cgr.dev/chainguard/apko build examples/alpine-base.yaml apko-alpine:edge apko-alpine.tar
Requirements and caveats from upstream:
- or, with Docker:
- You can then load the generated tar image into a Docker environment:

Fully reproducible by default. Run apko twice and you will get exactly the same binary.
-
Services. apko supports using the s6 supervision suite to run multiple processes
