Rate limiting for Apache James on top of Redis sentinel

Introduction

This guide provides step-by-step instructions for deploying a rate limiter for Apache James using Redis Sentinel.

The redis-sentinel in lab environment is structured with 6 nodes:

• 1 master node (M1)
• 2 replica nodes (R1, R2)
• 3 sentinel nodes (S1, S2, S3)

Configuration file

• redis.properties file sample:

redisURL=redis-sentinel://your_password@redis-sentinel-1:26379,redis-sentinel-2:26379,redis-sentinel-3:26379?sentinelMasterId=mymaster
redis.topology=master-replica

• Another configuration file of Apache James is similar to the one in the rate-limiter-redis guide.

How to run

Run docker-compose with the following command:

docker-compose up -d -f docker-compose-with-redis-sentinel.yml
