Chainguard Image now available for Apache Zookeeper

Apache Zookeeper is one of the most widely used programs for distributed coordination in the industry, powering some of the most critical and highly available systems and platforms. Today, we’re excited to announce a new Chainguard Image for Apache Zookeeper.

‍

Chainguard’s build of Zookeeper is powered by Wolfi, which means it comes with our own OpenJDK JRE and is built from source using our trusted build system. Our Images are minimal and hardened to run as a non-root user on a locked down filesystem.

‍

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/zookeeper

The Chainguard Zookeeper image is a fraction of the size of several alternatives and comes with our zero-known CVE target. Here’s how the numbers stack up:

If you want to see upwards of a 50% reduction in your Zookeeper Image sizes with more security built in by default, start using Chainguard’s Zookeeper Image today at github.com/chainguard-images, or get started with our Zookeeper Image using documentation in Chainguard Academy. Chainguard Images are now available for 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.
