This image is comparable to the rancher/rancher image available from Docker Hub. Switching to the Chainguard image should not require any changes to your existing setup.
You can run the following command to use Chainguard's Rancher image:
If you are deploying Rancher in an airgapped environment, you will also need to use the bundled system chart:
Now, jump to https://localhost:443 in your browser and log in with the username admin
and the password you set in the CATTLE_BOOTSTRAP_PASSWORD
environment variable. Process the certificate warning in your browser and you should see the Rancher quick start wizard.
For complete instructions on installing this image with Helm, please refer to the Helm Chart documentation. As a prerequisite, you may need to install cert-manager
in your cluster.
The following is an example of how to use the Helm chart, using the Chainguard image.
Start by adding a values.yaml
file to configure the Helm chart:

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:
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.
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.
