Redis Cluster Docker Swarm | How-to Guide

If you are looking for a guide to help you create a Redis cluster, you have come to the right place.

Here are a few options recommended by our experts:

• Redis Cluster mode:

  Redis offers a built-in clustering mode. This allows us to create a Redis cluster manually. We have to manually configure and manage the cluster. This includes including setting up the appropriate Redis instances and configuring cluster nodes. Furthermore, this method does not involve Docker Swarm.
• Use a Redis clustering solution:

  Rather than relying on Docker Swarm, we can use a Redis clustering solution designed for containerized environments. A popular option is Redis Cluster Manager. It helps manage Redis clusters in a containerized environment.

  Furthermore, it can be used with Docker Swarm to simplify the process of creating and managing a Redis cluster.

How to use Redis Cluster Manager with Docker Swarm

1. First, we have to start the Docker Swarm on our Docker host machine with the docker swarm init command.
2. Then, we must create an overlay network in Docker Swarm that will be used for communication between the cluster nodes.
3. Now, it is time to deploy multiple Redis instances as separate services in Docker Swarm. Additionally, each Redis instance has to be configured with the appropriate settings for clustering.
4. Next, we must deploy RCM as a separate service in Docker Swarm. Redis Cluster Manager will provide the needed management capabilities for the Redis cluster.
5. Then, we can use a Redis client or Redis CLI to connect to Redis Cluster Manager. We can interact with Redis Cluster Manager to create and manage the Redis cluster.
