The ztunnel component of ambient mesh

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/ztunnel: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 compatible with the distroless version of the upstream image. This is the image that gets deployed by default when you run helm install ztunnel istio/ztunnel -n istio-system. The upstream project releases two container images, one with a shell and package manager and one without. This image is based on the distroless version of the upstream image. If you want to use the image with a shell and package manager, you can use the -dev variant of this image.

Getting Started

For getting started, we can use helm to deploy istio in ambient mesh mode. The details to install istio in ambient mode can be found on official documentation

When deploying the ztunnel helm chart, we need to override the

helm install ztunnel istio/ztunnel -n istio-system --set hub=cgr.dev/chainguard --set image=ztunnel --set tag=latest

If you're using values.yaml file, you can add the following lines to override the image:

hub: cgr.dev/chainguard
image: ztunnel
tag: latest

Before installation, this can also be verified by running the following command:

helm repo add istio https://istio-release.storage.googleapis.com/charts
helm repo update
helm template ztunnel istio/ztunnel -n istio-system -f values.yaml

Documentation and Resources

After installation, we can follow the starting guide of an application which can be found here

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.
