Chainguard Image for harbor-registry

A Wolf-based image for Harbor - an open-source container registry with policies and RBAC, vulnerability scans, and provides trusted image signing.

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

This image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/harbor-registry:latest

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

Deploying Harbor with Helm

The easiest way to get up and running with Chainguard's Harbor images is via deployment with Harbor's official Helm chart.

To get started, we need to add Harbor's Helm repository:

helm repo add harbor https://helm.goharbor.io

Now that we've added the repository, we can deploy Harbor!:

helm install harbor harbor/harbor \
  --set core.image.repository=cgr.dev/chainguard/harbor-core,core.image.tag=latest \
  --set jobservice.image.repository=cgr.dev/chainguard/harbor-jobservice,jobservice.image.tag=latest \
  --set portal.image.repository=cgr.dev/chainguard/harbor-portal,portal.image.tag=latest \
  --set registry.registry.image.repository=cgr.dev/chainguard/harbor-registry,registry.registry.image.tag=latest \
  --set registry.registryctl.image.repository=cgr.dev/chainguard/harbor-registryctl,registry.registryctl.image.tag=latest \
  --set trivy.image.repository=cgr.dev/chainguard/harbor-trivy-adapter,trivy.image.tag=latest

You will need to override the image and tag values for each image like we've done here to point to Chainguard's Harbor images and tags.

Additionally, you may fetch Harbor's Helm chart after adding the repository and edit values directly without overriding them on installation:

helm fetch harbor/harbor --untar

Afterwards, edit values.yml and substitute in Chainguard's images/tags. For instance, for harbor-core, the following changes should be made:

core:
  ...
  image: cgr.dev/chainguard/harbor-core
  tag: latest
  ...

And then deploy after configuration:

helm install harbor .

For more information on deploying Harbor via Helm, see the official documentation here.

Deploying Harbor with Docker Compose

Harbor provides an online installer that can be retrieved from their releases on GitHub here.

Follow all of their steps for installation up until you've successfully generated your docker-compose.yml. At this point, you can swap the upstream images out for Chainguard's.

For instance, to switch out harbor-core with Chainguard's image, edit docker-compose.yml and make the following change:

services:
  ...
  core:
    image: cgr.dev/chainguard/harbor-core:latest
  ...

Then run the following in the terminal:

docker-compose up

Now you're up and running with Harbor powered by Chainguard images!

Usage

Now that you've deployed Harbor, the portal should be accessible on whatever host you've opted to use. For example, if configured to use localhost, the portal will be accessible at localhost:80 via HTTP or localhost:443 via HTTPS, if setup.

You may now login with the username and password you've set or via the default username and password, admin and Harbor12345. You'll be presented with several options, including the ability to create a new project in the registry.

Additionally, you can now login to the registry with Docker! To do so, open a terminal and run:

docker login localhost

Where localhost should be substituted with the hostname or external URL you've chosen for Harbor.

Now let's push an image using Chainguard's base container for Wolfi!

Pull Wolfi:

docker pull cgr.dev/chainguard/wolfi-base:latest

Tag Wolfi using the registry and project path (library is created by default):

docker tag cgr.dev/chainguard/wolfi-base:latest locahost/library/wolfi-base:latest

And finally, push Wolfi to the registry!:

docker push localhost/library/wolfi-base:latest

Wolfi is now being pushed to the registry and will be viewable in the portal.

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.
