Redis using Elasticache

Setup for Redis using AWS Elasticache

• Usage
• High Availability
• Access

Usage

Remember to check out the variables and outputs to see all options.

module "elasticache" {
  source = "github.com/nsbno/terraform-aws-redis?ref=x.y.z"

  application_name = "my-cool-train-status-thingy"
  security_group_ids = [aws_security_group.this.id]

  subnet_ids = data.aws_subnet_ids.private.ids
}

High Availability

The availability_zones variable decides if the cluster is spun up in high availability.

If it is set up, it will set up the amount of nodes needed to match the AZs and enable automatic failover.

Access

Only the given security_group_ids can access the cluster.

If you want to grant additional services access to the cluster, make sure to either add them to the list or manually grant access using the security_group_id output.
