Chainguard Images are regularly-updated, minimal container images with low-to-zero CVEs.

Download this Image

This image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/apko-fips:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard registry.

Getting Started

The following example builds an nginx image and covers the full range of apko features:

• Create a new file named apko-test.yaml with the following content:

  contents:
  repositories:
      - https://dl-cdn.alpinelinux.org/alpine/edge/main
  packages:
      - alpine-baselayout
      - nginx
  
  entrypoint:
  type: service-bundle
  services:
      nginx: /usr/sbin/nginx -c /etc/nginx/nginx.conf -g "daemon off;"
  
  stop-signal: SIGQUIT
  
  work-dir: /usr/share/nginx
  
  accounts:
  groups:
      - groupname: nginx
      gid: 10000
  users:
      - username: nginx
      uid: 10000
      shell: /bin/sh
  run-as: nginx
  
  # optional environment configuration
  environment:
  PATH: /usr/sbin:/sbin:/usr/bin:/bin
  
  # optional path mutations
  paths:
  - path: /run/nginx
      type: directory
      uid: 10000
      gid: 10000
      permissions: 0o755
  - path: /etc/nginx/http.d/default.conf
      type: hardlink
      source: /usr/share/nginx/http-default_server.conf
      uid: 10000
      gid: 10000
      permissions: 0o644
  
  archs:
  - amd64
  - 386
  
  annotations:
  foo: bar
  bar: baz

• You can then build this using the apko image:

  docker run -v "$PWD":/work cgr.dev/ORGANIZATION/apko-fips build apko-test.yaml apko-test:test apko-test.tar

What are Chainguard Images?

Chainguard Images are a collection of container images designed for security and minimalism.

Many Chainguard Images are distroless; they contain only an open-source application and its runtime dependencies. These images do not even contain a shell or package manager. Chainguard Images are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a secure software supply chain.

The main features of Chainguard Images include:

• Minimal design, with no unnecessary software bloat
• Automated nightly builds to ensure Images are completely up-to-date and contain all available security patches
• High quality build-time SBOMs (software bills of materials) attesting the provenance of all artifacts within the Image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

-dev Variants

As mentioned previously, Chainguard’s distroless Images have no shell or package manager by default. This is great for security, but sometimes you need these things, especially in builder images. For those cases, most (but not all) Chainguard Images come paired with a -dev variant which does include a shell and package manager.

Although the -dev image variants have similar security features as their distroless versions, such as complete SBOMs and signatures, they feature additional software that is typically not necessary in production environments. The general recommendation is to use the -dev variants only to build the application and then copy all application artifacts into a distroless image, which will result in a final container image that has a minimal attack surface and won’t allow package installations or logins.

That being said, it’s worth noting that -dev variants of Chainguard Images are completely fine to run in production environments. After all, the -dev variants are still more secure than many popular container images based on fully-featured operating systems such as Debian and Ubuntu since they carry less software, follow a more frequent patch cadence, and offer attestations for what they include.
