# Self Managed Node Groups Example

Configuration in this directory creates an AWS EKS cluster with various Self Managed Node Groups (AutoScaling Groups) demonstrating the various methods of configuring/customizing:

- A default, "out of the box" self managed node group as supplied by the `self-managed-node-group` sub-module
- A Bottlerocket self managed node group that demonstrates many of the configuration/customizations offered by the `self-manged-node-group` sub-module for the Bottlerocket OS
- A self managed node group that demonstrates nearly all of the configurations/customizations offered by the `self-managed-node-group` sub-module

See the [AWS documentation](https://docs.aws.amazon.com/eks/latest/userguide/managed-node-groups.html) for further details.

## Usage

To run this example you need to execute:

```bash
$ terraform init
$ terraform plan
$ terraform apply
```

Note that this example may create resources which cost money. Run `terraform destroy` when you don't need these resources.
