Add integration

Deploy

This Helm chart deploys a Distributed Redis cluster on Kubernetes with master-slave replication, high availability, and monitoring capabilities. Below is a detailed guide to the configuration options available.


Add Helm Repository

Add the Helm repository by running:

For more details, see the Helm Repository Documentation.


Install Helm Chart

To deploy the Redis Distributed Helm chart, use the following command:

helm install [RELEASE_NAME]

Replace [RELEASE_NAME] with your desired release name. Example:

You can override default values during installation by providing a values.yaml file.
Refer to the Helm Install Documentation for further details.

Uninstall Helm Chart
To remove the Redis Distributed Helm chart and associated resources, run:
helm uninstall [RELEASE_NAME]
Example:

Features
  • Deploy Redis master-slave architecture with high availability on Kubernetes.
  • Configurable master and slave resources, persistence, and scaling options.
  • Built-in health monitoring with liveness and readiness probes.
  • Automatic failover and replication management for data reliability.
  • Comprehensive monitoring with Redis Exporter and Prometheus integration.
  • Customizable service types and ports for flexible networking.
  • Rolling updates with zero downtime for seamless deployments.
  • Persistent storage for both master and slave nodes.

Monitoring
The chart includes a Redis Exporter container that exposes metrics on port 2121. These metrics are automatically collected by Prometheus when using the Prometheus Operator.
Key metrics include:
  • Redis instance information
  • Connected slaves count
  • Memory usage
  • Command statistics
  • Replication status
  • Connection metrics
