Redis Module

Port of the Redis helm chart for Terraform

Description

Open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

(http://redis.io/)

Requirements

This module requires an unofficial Kubernetes provider fork, available here. The fork provides support for additional resource types (Deployment, StatefulSet) that are currently not available in the official build.

Example Usage

module redis {
  source = "git::https://github.com/sl1pm4t/terraform-kubernetes-redis"

  kubernetes_namespace = "redis"

  master_resource_limits = {
    cpu    = "500m"
    memory = "2Gi"
  }
  
  slave_replica_count  = 1
}
