AWS.Compute.EKSSelfManagedNode

compute

Properties that define the computing parameters for the Amazon EKS self-managed nodes, such as, Amazon EC2 instance types and Amazon EC2 instance AMIs.

ami_id

The AMI ID used to launch the instance. AWS TNB supports instances that leverage IMDSv2. For more information, see IMDS version.

Note

You can update the AMI ID for EKSSelfManagedNode. The Amazon EKS version of the AMI must be the same as or up to 2 versions lower than the Amazon EKS cluster version. For example if the Amazon EKS cluster version is 1.31, then the Amazon EKS AMI version must be 1.31, 1.30, or 1.29.

Required: Yes

Type: String

instance_type

The instance size.

Required: Yes

Type: String

key_pair

The Amazon EC2 key pair to enable SSH access.

Required: Yes

Type: String

root_volume_encryption

Enables Amazon EBS encryption for the Amazon EBS root volume. If this property is not provided, AWS TNB encrypts Amazon EBS root volumes by default.

Required: No

Default: true

Type: Boolean

root_volume_encryption_key_arn

The ARN of the AWS KMS key. AWS TNB supports regular key ARN, multi-region key ARN and alias ARN.

Required: No

Type: String

Note

• If root_volume_encryption is false, do not include root_volume_encryption_key_arn.

• AWS TNB supports root volume encryption of Amazon EBS-backed AMI’s.

• If the AMI's root volume is already encrypted, you must include the root_volume_encryption_key_arn for AWS TNB to re-encrypt the root volume.

• If the AMI's root volume is not encrypted, AWS TNB uses the root_volume_encryption_key_arn to encrypt the root volume.

  If you do not include root_volume_encryption_key_arn, AWS TNB uses AWS Managed Services to encrypt the root volume.

• AWS TNB does not decrypt an encrypted AMI.

scaling

Properties that define the scaling parameters for the Amazon EKS self-managed nodes, such as, the desired number of Amazon EC2 instances, and minimum and maximum number of Amazon EC2 instances in the node group.

desired_size

The number of instances in this NodeGroup.

Required: Yes

Type: Integer

min_size

The minimum number of instances in this NodeGroup.

Required: Yes

Type: Integer

max_size

The maximum number of instances in this NodeGroup.

Required: Yes

Type: Integer

node_role

The ARN of the IAM role that is attached to the Amazon EC2 instance.

Required: Yes

Type: String

tags

The tags to be attached to the resource. Tags will be propagated to the instances created by the resource.

Required: No

Type: List

cluster

An AWS.Compute.EKS node.

Required: Yes

Type: String

subnets

An AWS.Networking.Subnet node.

Required: Yes

Type: List

network_interfaces

An AWS.Networking.ENI node. Ensure that the network interfaces and subnets are set to the same Availability Zone or instantiation will fail.

When you set network_interfaces, AWS TNB obtains the permission related to ENIs from the multus_role property if you included the multus property in the AWS.Compute.EKS node. Otherwise, AWS TNB obtains the permission related to ENIs from the node_role property.

Required: No

Type: List

security_groups

An AWS.Networking.SecurityGroup node.

Required: No

Type: List

placement_group

A tosca.nodes.AWS.Compute.PlacementGroup node.

Required: No

Type: String

user_data

A tosca.nodes.AWS.Compute.UserData node reference. A user data script is passed to the Amazon EC2 instances launched by the self-managed node group. Add the permissions required for executing custom user data to the node_role passed to the node group.

Required: No

Type: String

labels

A list of node labels. A node label must have a name and a value. Create a label using the following criteria:

• The name and value must be separated by =.

• The name and value can each be up to 63 characters in length.

• The label can include letters (A-Z, a-z,), numbers (0-9), and the following characters: [-, _, ., *, ?]

• The name and value must start and end with an alphanumeric, ?, or * character.

For example, myLabelName1=*NodeLabelValue1

Required: No
