-**Important Note**: We suggest managing node groups as independent resources, as shown in this example. This approach enables you to add or remove node groups without having to rebuild the entire cluster. If you embed node groups directly within the vngcloud_vks_cluster resource, you will need to recreate the cluster to remove them.

 * `enable_private_nodes` - (Optional) You can choose the mode that you want your node group works.  The VKS public node groups include worker nodes deployed in public subnets within a VPC.  These worker nodes have public IP addresses and CAN communicate directly with the public internet. The private node groups configuration involves deploying worker nodes within subnets of a VPC, ensuring they cannot directly access the public internet. All outbound traffic from these nodes is routed exclusively through a NAT gateway service. The default value is "false".
 * `security_groups` - (Optional) - Specifies the security group for your cluster. A security group acts as a virtual firewall, controlling inbound and outbound traffic for associated resources. You can find the Security Group ID on the vServer Portal and input it here.
 * `ssh_key_id` - (Required) - Specifies the SSH key for secure credentials to prove your identity when connecting to the server. You can import a key and get the SSH Key ID on the vServer Portal to input here
