What is Apache ZooKeeper?

The apache-zookeeper image runs Apache ZooKeeper, a distributed coordination service that provides configuration management, naming, distributed synchronization, and group services. It has been a hard dependency for older Apache Kafka deployments and a foundation for HBase, Hadoop, and other big-data systems. ZooKeeper deploys as an ensemble (typically 3 or 5 nodes) that elects a leader and replicates state via the ZAB protocol.

What is Echo's Apache ZooKeeper image?

Echo's apache-zookeeper image bundles the standard ZooKeeper distribution on a hardened JRE and minimal base. Echo images are designed to be a drop-in replacement: change the FROM line in your Dockerfile and CVEs go to zero without breaking your app. Every image is tested across clouds, image use cases, and deployment targets. Echo ships every image in two variants: a distroless variant optimized for runtime use, and a default variant that includes essential build tools, package managers, and shells. The default variant supports four-letter-word debugging and snapshot inspection on a live node; the distroless variant suits clusters where management is fully automated and shells aren't needed.

What is the difference between Echo's Apache ZooKeeper image and the public Apache ZooKeeper image?

Public apache-zookeeper images bundle a broader JRE and OS layer than ZooKeeper actually uses. Echo's image trims to the essentials, dropping CVE counts on a workload that is often retained for years for backwards-compatibility reasons. Echo commits to a 7-day SLA for critical and high severity vulnerabilities, and 10 days for medium, low, and unknown - with vulnerabilities triaged within 24 hours. Echo images are recognized by all major scanners and mirrored to all major registries, so they fit into existing pipelines without changing your registry, scanner, or runtime tooling.

FAQ

Can I replace my apache-zookeeper image with Echo's apache-zookeeper image?

Yes. Echo's apache-zookeeper image is a drop-in replacement. Update the FROM line in your Dockerfile (or the image reference in your manifests) and your application keeps working - the CVEs disappear, the behavior doesn't.

What is Echo's vulnerability management SLA on the apache-zookeeper image?

Echo commits to a 7-day SLA for critical and high severity vulnerabilities, and 10 days for medium, low, and unknown - with vulnerabilities triaged within 24 hours. Patches are mirrored automatically into your private registry so you're always running a clean version.

Is Echo's apache-zookeeper image distroless?

Echo ships every image in two variants: a distroless variant optimized for runtime use, and a default variant that includes essential build tools, package managers, and shells.

How does Echo achieve such a drastic CVE reduction in apache-zookeeper?

Echo apache-zookeeper is built from source with only the absolute essentials needed to run the workload, which significantly shrinks the attack surface. Echo also patches aggressively over time, with backports available so you can stay on the version that works for you without forcing a functional change for the sake of security.

Will Echo's apache-zookeeper image help us achieve FedRAMP?

Yes. The hard parts of FedRAMP - managing vulnerabilities, applying fixes, and using FIPS-validated cryptography - are baked into Echo images, including STIG-hardened configuration and ConMon/POA&M-ready reporting.
