Creates an Amazon EKS Cluster control plane.
Optionally, can also create the supporting compute architecture:
- If argument 'compute' is provided with a value of 'nodegroup', will also
attempt to create an Amazon EKS Managed Nodegroup for the cluster.
See :class:`~airflow.providers.amazon.aws.operators.EksCreateNodegroupOperator`
documentation for requirements.
- If argument 'compute' is provided with a value of 'fargate', will also attempt to create an AWS
Fargate profile for the cluster.
See :class:`~airflow.providers.amazon.aws.operators.EksCreateFargateProfileOperator`
documentation for requirements.

For more information on how to use this operator, take a look at the guide:
:ref:`howto/operator:EksCreateClusterOperator`
:param cluster_name: The unique name to give to your Amazon EKS Cluster. (templated)
:param cluster_role_arn: The Amazon Resource Name (ARN) of the IAM role that provides permissions for the
Kubernetes control plane to make calls to AWS API operations on your behalf. (templated)
:param resources_vpc_config: The VPC configuration used by the cluster control plane. (templated)
:param compute: The type of compute architecture to generate along with the cluster. (templated)
Defaults to 'nodegroup' to generate an EKS Managed Nodegroup.
:param create_cluster_kwargs: Optional parameters to pass to the CreateCluster API (templated)
:param wait_for_completion: If True, waits for operator to complete. (default: False) (templated)
:param aws_conn_id: The Airflow connection used for AWS credentials. (templated)
If this is None or empty then the default boto3 behaviour is used. If
running Airflow in a distributed manner and aws_conn_id is None or
empty, then the default boto3 configuration would be used (and must be
maintained on each worker node).
:param region: Which AWS region the connection should use. (templated)
If this is None or empty then the default boto3 behaviour is used.
If compute is assigned the value of 'nodegroup':
:param nodegroup_name: *REQUIRED* The unique name to give your Amazon EKS managed node group. (templated)
:param nodegroup_role_arn: *REQUIRED* The Amazon Resource Name (ARN) of the IAM role to associate with
the Amazon EKS managed node group. (templated)
:param create_nodegroup_kwargs: Optional parameters to pass to the CreateNodegroup API (templated)
If compute is assigned the value of 'fargate':
:param fargate_profile_name: *REQUIRED* The unique name to give your AWS Fargate profile. (templated)
:param fargate_pod_execution_role_arn: *REQUIRED* The Amazon Resource Name (ARN) of the pod execution
role to use for pods that match the selectors in the AWS Fargate profile. (templated)
:param fargate_selectors: The selectors to match for pods to use this AWS Fargate profile. (templated)
:param create_fargate_profile_kwargs: Optional parameters to pass to the CreateFargateProfile API
(templated)
:param waiter_delay: Time (in seconds) to wait between two consecutive calls to check cluster state
:param waiter_max_attempts: The maximum number of attempts to check cluster state
:param deferrable: If True, the operator will wait asynchronously for the job to complete.
This implies waiting for completion. This mode requires aiobotocore module to be installed.
