About zookeeper

Current Apache ZooKeeper Docker Image from Canonical, based on Ubuntu. Receives security updates and tracks the newest combination of Apache ZooKeeper and Ubuntu. This repository is free to use and exempted from per-user rate limits.

About Apache ZooKeeper

ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or another by distributed applications. Read more on the Apache website. This image is shipped in support of the Apache Kafka image.

Please note that the images tagged up to 3.1 are Dockerfile-base images, whereas from version 3.8.2 onward the images are now rocks. As such the entrypoint is now Pebble. Read more on the Rockcraft docs.

Channel Tags shows the most stable channel for that track ordered stable, candidate, beta, edge. More risky channels are always implicitly available. So if beta is listed, you can also pull edge. If candidate is listed, you can pull beta and edge. When stable is listed, all four are available. Images are guaranteed to progress through the sequence edge, beta, candidate before stable.
