Rancher CAPI extension

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/rancher-turtles:latest

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

Compatibility Notes

This image is a drop-in replacement for the upstream rancher/turtles image. It is built with Go from the upstream rancher/turtles source (Apache License 2.0) and, like the upstream image, uses /manager as its entrypoint and runs as the nonroot user (UID 65532) by default.

Getting Started

Rancher Turtles is a Kubernetes operator that integrates Rancher Manager with Cluster API (CAPI). It reconciles CAPIProvider and ClusterctlConfig custom resources, drives the Cluster API Operator to install CAPI providers, and auto-imports CAPI-provisioned clusters into Rancher.

The controller-manager serves metrics on port 8080, health probes on port 9440, and its admission webhook on port 9443. These ports are configured through command-line flags set by the Helm chart.

Installation

Using Helm Chart

Rancher Manager must already be installed in the cluster before you deploy Rancher Turtles. The controller-manager depends on the Rancher Manager cluster CRDs, and the upstream chart requires Rancher 2.15 or later. Without them, the manager exits with problem running manager. Refer to the Rancher installation documentation for instructions.

Rancher Turtles also requires cert-manager. If it is not already present, install it first:

helm repo add jetstack https://charts.jetstack.io
helm repo update
helm install cert-manager jetstack/cert-manager \
  --namespace cert-manager \
  --create-namespace \
  --set crds.enabled=true

Then add the public Rancher Turtles Helm repository and install the chart with the Chainguard image:

helm repo add turtles https://rancher.github.io/turtles
helm repo update
helm install rancher-turtles turtles/rancher-turtles \
  --namespace cattle-turtles-system \
  --create-namespace \
  --set image.repository=cgr.dev/ORGANIZATION/rancher-turtles \
  --set image.tag=latest \
  --wait

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
