Chainguard Image now available for NATS

NATS is a high-performance, cloud-native messaging system designed for edge and cloud use cases. We’re excited to announce we now have a hardened Chainguard Image for NATS. The Chainguard NATS Image is built on Wolfi, our secure by default operating system for containerized workloads that allows for minimal Images built with our hardened toolchain.

To get started with the Chainguard NATS Image pull the following and run it:

We also offer a development NATS Image variant that contains a few extra utilities, like the nats CLI and the nsc tool, for working with NATS and associated configurations and authentication tokens. This Image is available at cgr.dev/chainguard/nats:latest-dev. The Chainguard NATS Image is over 50% smaller than other similar options and comes with our zero-known CVE target. See the numbers for yourself:

As always, the binaries in our Images are built from source and come with comprehensive and SBOMs from the start. These SBOMs contain the package metadata for everything in the Image and can be used for vulnerability scanning or license compliance. You can download the SBOMs for these containers with cosign:

$ cosign download sbom --platform=linux/amd64 cgr.dev/chainguard/nats

If you want to see upwards of a 50% reduction in your NATS image sizes with more security built in by default, start using Chainguard’s NATS Image today at github.com/chainguard-images, or get started with our documentation in Chainguard Academy. Chainguard Images are now available for Apache Zookeeper, Bazel, curl, Git, Go, Jenkins, Postgres, Ruby and more. We currently offer our public Chainguard Images catalog for no cost to users, which includes features like SBOMs, signatures and SLSA Build Level 2 provenance information. If your organization requires patching SLAs, older version support or Images for compliance requirements, we offer Standard and Custom subscription tiers. Contact our team to learn more.
