Chainguard Container for fulcio-fips

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/fulcio-fips:latest

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

Compatibility Notes

The Chainguard fulcio-fips image is based on the sigstore/fulcio project and is comparable to container images built from the sigstore/fulcio repository. Fulcio is Sigstore's certificate authority for issuing short-lived code signing certificates based on OIDC identity.

FIPS Support

This Chainguard Container ships with a validated redistribution of OpenSSL's FIPS provider module. For more on FIPS support in Chainguard Containers, consult our guide on FIPS-enabled Chainguard Images on Chainguard Academy.

Prerequisites

Fulcio requires OIDC provider configuration for certificate issuance and certificate chains for key management setup. Refer to the Fulcio setup documentation for detailed configuration requirements.

Getting Started

Testing the Image

You can verify the fulcio-fips image works with the following command:

docker run --rm cgr.dev/ORGANIZATION/fulcio-fips:latest version

Check available commands:

docker run --rm cgr.dev/ORGANIZATION/fulcio-fips:latest --help

Running Fulcio Server

To start the Fulcio server with minimal testing configuration:

docker run --rm -p 8080:8080 cgr.dev/ORGANIZATION/fulcio-fips:latest serve --ca ephemeralca

This example uses an ephemeral certificate authority (CA) for testing purposes. Production deployments require proper OIDC configuration, certificate chains, and key management setup as detailed in the Sigstore documentation.

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro 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 -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
