# Keda Helm Chart | ||
|
||
KEDA allows for fine grained autoscaling (including to/from zero) for event driven Kubernetes workloads. | ||
|
||
## Installation | ||
Below terraform script shows how to use Keda Terraform Addon, A complete example is also given [here](https://github.com/clouddrove/terraform-helm-eks-addons/blob/master/_examples/complete/main.tf). | ||
```bash | ||
module "addons" { | ||
source = "clouddrove/eks-addons/aws" | ||
version = "0.0.9" | ||
|
||
depends_on = [module.eks.cluster_id] | ||
eks_cluster_name = module.eks.cluster_name | ||
|
||
keda = true | ||
} | ||
``` | ||
