Minimal FIPS image of step-ca, an online Certificate Authority (CA) for secure, automated X.509 and SSH certificate management
Chainguard Containers are regularly-updated, secure-by-default container images.
For those with access, this container image is available on cgr.dev
:
Be sure to replace the ORGANIZATION
placeholder with the name used for your organization's private repository within the Chainguard Registry.
The Chainguard step-ca-fips
image is a minimal drop-in replacement for the upstream smallstep/step-ca container image. It provides equivalent functionality for operating a private Certificate Authority (CA) and is fully compatible with official configurations and the smallstep Helm chart. This image is designed to be a minimal, secure alternative that runs as a non-root user. Switching to this image should not require any changes to your existing deployment configuration.
Chainguard's step-ca-fips
image ships with a validated redistribution of the OpenSSL FIPS provider module. For more on FIPS support in Chainguard container images, consult the guide on FIPS-enabled Chainguard Images on Chainguard Academy.
You can deploy this image using the step-ca Helm chart. Be sure to override the image by setting the following values in a values.yaml
file:
Be sure to replace the ORGANIZATION
placeholder with the name used for your organization's private repository within the Chainguard registry.
Then, deploy the step-ca
helm chart.
Once deployed, you can issue a certificate using the step CLI by port-forwarding the CA service and referencing the provisioner and root certificate.
If successful, step
will issue a TLS certificate signed by the step-ca instance.
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.
