Self-managed Node Group example node fails to join cluster

[RyanTimoney]

Description

I've cloned the repo at 70866e6, commented out lines 75-302 within examples/self_managed_node_group/main.tf (this is the content within self_managed_nod_groups except for default_node_group = {}) and applied it. coredns fails to deploy and the one node that is created does not join the cluster.

• ✋ I have searched the open/closed issues and my issue is not listed.

Versions

• Module version [Required]: 20.8.4 (this also fails on 20.8.3)
• Terraform version: 1.7.5
• Provider version(s):

Terraform v1.7.5
on darwin_amd64
+ provider registry.terraform.io/hashicorp/aws v5.41.0
+ provider registry.terraform.io/hashicorp/cloudinit v2.3.3
+ provider registry.terraform.io/hashicorp/null v3.2.2
+ provider registry.terraform.io/hashicorp/time v0.11.1
+ provider registry.terraform.io/hashicorp/tls v4.0.5

Reproduction Code [Required]

1. Clone the repo at 70866e6
2. CD to examples/self_managed_node_group
3. Within main.tf, comment out lines 75-302. Within the self_managed_node_groups map, only default_node_group = {} will remain.
4. terraform init
5. terraform apply

• No workspace
• No cache
• This was in an empty AWS region. No custom VPC was present.
• I've got AdministratorAccess within this account

Expected behavior

CoreDNS installs successfully and the node joins the cluster.

Actual behavior

After 20 minutes, this error is thrown:

╷
│ Warning: Running terraform apply again will remove the kubernetes add-on and attempt to create it again effectively purging previous add-on configuration

While the Auto Scaling Group is created with what seems to be appropriate tags, no nodes join the cluster.
