Cloudflare Tunnel client (formerly Argo Tunnel)

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/cloudflared-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 cloudflared image is built with the standard Go toolchain, rather than Cloudflare’s patched fork. It is otherwise functionally equivalent to the upstream cloudflared container image.

This image enables integration into security-focused environments and reproducible builds while maintaining full compatibility with expected cloudflared behavior.

FIPS Support

The cloudflared-fips Chainguard Image ships with a validated redistribution of the OpenSSL's FIPS provider module. For more on FIPS support in Chainguard Images, consult the guide on FIPS-enabled Chainguard Images on Chainguard Academy

Quick Start

You can quickly get started with the cloudflared image using Docker:

docker run -it cgr.dev/ORGANIZATION/cloudflared-fips:latest tunnel --no-autoupdate --hello-world

This command runs the built-in hello-world tunnel check.

To start cloudflared as a DNS proxy on port 1053, run:

docker run -it -p 1053:5053/tcp -p 1053:5053/udp cgr.dev/ORGANIZATION/cloudflare-fips:latest proxy-dns

Notes

• The upstream Helm chart documentation has not been updated in several months; using this chart is not recommended.

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.
