Docker Redis

Introduction

What is Redis?

Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions, and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.

What is Redis Sentinel?

Redis Sentinel provides high availability for Redis. In practical terms this means that using Sentinel you can create a Redis deployment that resists without human intervention certain kinds of failures. Redis Sentinel also provides other collateral tasks such as monitoring, notifications and acts as a configuration provider for clients. Learn more here⁠.

Features

• Based off latest version of Redis.
• Included bash scripts to run Redis Sentinel easily in Kubernetes.
• Included examples of Kubernetes manifests to run Redis Sentinel in Kubernetes (suitable for production).
