Krause

Krause allows one to easily setup an eventually consistent, highly available, Redis-compatible datastore. It is suitable as a cache or message broker.

Overview

KeyDB is a fork of Redis which strives to maintain 100% compatibility with the Redis wire protocol. Krause is a wrapper which assists with running KeyDB on multiple nodes within Docker Swarm by adding automatic discovery to KeyDB.

Krause enables automatic discovery by querying Swarm's DNS server for a lookup of tasks.<service-name>.

Example

docker network create --opt encrypted --driver overlay --attachable keydb
