2020/03/24 - Amazon Elastic Kubernetes Service - 3 updated api methods
Changes Adding new error codes: Ec2SubnetInvalidConfiguration and NodeCreationFailure for Nodegroups in EKS
{'nodegroup': {'health': {'issues': {'code': {'Ec2SubnetInvalidConfiguration',
'NodeCreationFailure'}}}}}
Creates a managed worker node group for an Amazon EKS cluster. You can only create a node group for your cluster that is equal to the current Kubernetes version for the cluster. All node groups are created with the latest AMI release version for the respective minor Kubernetes version of the cluster.
An Amazon EKS managed node group is an Amazon EC2 Auto Scaling group and associated Amazon EC2 instances that are managed by AWS for an Amazon EKS cluster. Each node group uses a version of the Amazon EKS-optimized Amazon Linux 2 AMI. For more information, see Managed Node Groups in the Amazon EKS User Guide .

string
[REQUIRED]
The unique name to give your node group.
dict
The scaling configuration details for the Auto Scaling group that is created for your node group.
minSize (integer) --
The minimum number of worker nodes that the managed node group can scale in to. This number must be greater than zero.

integer
The root device disk size (in GiB) for your node group instances. The default disk size is 20 GiB.

(string) --
list
The instance type to use for your node group. Currently, you can specify a single instance type for a node group. The default value for this parameter is t3.medium . If you choose a GPU instance type, be sure to specify the AL2_x86_64_GPU with the amiType parameter.
(string) --
string
The AMI type for your node group. GPU instance types should use the AL2_x86_64_GPU AMI type, which uses the Amazon EKS-optimized Linux AMI with GPU support. Non-GPU instances should use the AL2_x86_64 AMI type, which uses the Amazon EKS-optimized Linux AMI.

For more information, see Security Groups for Your VPC in the Amazon Virtual Private Cloud User Guide .
(string) --
string
[REQUIRED]
The Amazon Resource Name (ARN) of the IAM role to associate with your node group. The Amazon EKS worker node kubelet daemon makes calls to AWS APIs on your behalf. Worker nodes receive permissions for these API calls through an IAM instance profile and associated policies. Before you can launch worker nodes and register them into a cluster, you must create an IAM role for those worker nodes to use when they are launched. For more information, see Amazon EKS Worker Node IAM Role in the * Amazon EKS User Guide * .
dict
The Kubernetes labels to be applied to the nodes in the node group when they are created.
(string) --
(string) --
dict
The metadata to apply to the node group to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define. Node group tags do not propagate to any other resources associated with the node group, such as the Amazon EC2 instances or subnets.

(string) --
string
Unique, case-sensitive identifier that you provide to ensure the idempotency of the request.
This field is autopopulated if not provided.
string
The Kubernetes version to use for your managed nodes. By default, the Kubernetes version of the cluster is used, and this is the only accepted specified value.
string
The AMI version of the Amazon EKS-optimized AMI to use with your node group. By default, the latest available AMI version for the node group's current Kubernetes version is used. For more information, see Amazon EKS-Optimized Linux AMI Versions in the Amazon EKS User Guide .
