2018/08/31 - Amazon Elastic Container Service for Kubernetes - 3 updated api methods
Changes Amazon EKS DescribeCluster API returns a platformVersion attribute which allows you to identify the features that are currently enabled for your clusters. The Amazon EKS platform version represents capabilities of the cluster control plane, such as which Kubernetes API server flags are enabled, as well as the current Kubernetes patch version.
{'cluster': {'platformVersion': 'string'}}
Creates an Amazon EKS control plane.
The Amazon EKS control plane consists of control plane instances that run the Kubernetes software, like etcd and the API server. The control plane runs in an account managed by AWS, and the Kubernetes API is exposed via the Amazon EKS API server endpoint.
Amazon EKS worker nodes run in your AWS account and connect to your cluster's control plane via the Kubernetes API server endpoint and a certificate file that is created for your cluster.
The cluster control plane is provisioned across multiple Availability Zones and fronted by an Elastic Load Balancing Network Load Balancer. Amazon EKS also provisions elastic network interfaces in your VPC subnets to provide connectivity from the control plane instances to the worker nodes (for example, to support kubectl exec , logs , and proxy data flows).
After you create an Amazon EKS cluster, you must configure your Kubernetes tooling to communicate with the API server and launch worker nodes into your cluster. For more information, see Managing Cluster Authentication and Launching Amazon EKS Worker Nodes in the Amazon EKS User Guide .

Request Syntax
client.create_cluster(
name='string',
version='string',
roleArn='string',
resourcesVpcConfig={
'subnetIds': [
'string',
],
'securityGroupIds': [
'string',
]
},
clientRequestToken='string'
)
string
[REQUIRED]
The unique name to give to your cluster.
string
The desired Kubernetes version for your cluster. If you do not specify a value here, the latest version available in Amazon EKS is used.
string
[REQUIRED]
The Amazon Resource Name (ARN) of the IAM role that provides permissions for Amazon EKS to make calls to other AWS API operations on your behalf. For more information, see Amazon EKS Service IAM Role in the * Amazon EKS User Guide * .
dict
[REQUIRED]
The VPC subnets and security groups used by the cluster control plane. Amazon EKS VPC resources have specific requirements to work properly with Kubernetes. For more information, see Cluster VPC Considerations and Cluster Security Group Considerations in the Amazon EKS User Guide . You must specify at least two subnets. You may specify up to 5 security groups, but we recommend that you use a dedicated security group for your cluster control plane.
subnetIds (list) -- [REQUIRED]
Specify subnets for your Amazon EKS worker nodes. Amazon EKS creates cross-account elastic network interfaces in these subnets to allow communication between your worker nodes and the Kubernetes control plane.
(string) --
securityGroupIds (list) --
Specify one or more security groups for the cross-account elastic network interfaces that Amazon EKS creates to use to allow communication between your worker nodes and the Kubernetes control plane.
(string) --
string
Unique, case-sensitive identifier you provide to ensure the idempotency of the request.
This field is autopopulated if not provided.

{'cluster': {'platformVersion': 'string'}}
Deletes the Amazon EKS cluster control plane.
Note
If you have active services in your cluster that are associated with a load balancer, you must delete those services before deleting the cluster so that the load balancers are deleted properly. Otherwise, you can have orphaned resources in your VPC that prevent you from being able to delete the VPC. For more information, see Deleting a Cluster in the Amazon EKS User Guide .
