Clear Linux* OS cassandra container image

What is this image?

clearlinux/cassandra is a Docker image with cassandra running on top of the official clearlinux base image.

Cassandra is a free and open-source, distributed, wide column store, NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple datacenters, with asynchronous masterless replication allowing low latency operations for all clients.

Why use a clearlinux based image?

Clear Linux* OS is an open source, rolling release Linux distribution optimized for performance and security, from the Cloud to the Edge, designed for customization, and manageability.

Clear Linux* OS based container images use:

• Optimized libraries that are compiled with latest compiler versions and flags.
• Software packages that follow upstream source closely and update frequently.
• An aggressive security model and best practices for CVE patching.
• A multi-staged build approach to keep a reduced container image size.
• The same container syntax as the official images to make getting started easy.
