EKS

Client ¶

class EKS.Client¶

A low-level client representing Amazon Elastic Container Service for Kubernetes (EKS):

import boto3

client = boto3.client('eks')

These are the available methods:

can_paginate()
create_cluster()
delete_cluster()
describe_cluster()
generate_presigned_url()
get_paginator()
get_waiter()
list_clusters()

can_paginate(operation_name)¶

Check if an operation can be paginated.

Parameters: operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns: True if the operation can be paginated, False otherwise.

create_cluster(**kwargs)¶

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 .

        ],
        'securityGroupIds': [
            'string',
        ]
    },
    clientRequestToken='string'
)

Parameters

name (string) --
[REQUIRED]

The unique name to give to your cluster.
version (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.
roleArn (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 * .
resourcesVpcConfig (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) --

delete_cluster(**kwargs)¶

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 .

generate_presigned_url(ClientMethod, Params=None, ExpiresIn=3600, HttpMethod=None)¶

Generate a presigned url given a client, its method, and arguments

Parameters

ClientMethod (string) -- The client method to presign for
Params (dict) -- The parameters normally passed to ClientMethod.
ExpiresIn (int) -- The number of seconds the presigned url is valid for. By default it expires in an hour (3600 seconds)

Returns

The presigned url

get_paginator(operation_name)¶

Create a paginator for an operation.

Parameters: operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Raises OperationNotPageableError: Raised if the operation is not pageable. You can use the client.can_paginate method to check if an operation is pageable.
Return type: L{botocore.paginate.Paginator}
Returns: A paginator object.

get_waiter(waiter_name)¶

Returns an object that can wait for some condition.

Parameters: waiter_name (str) -- The name of the waiter to get. See the waiters section of the service docs for a list of available waiters.
Returns: The specified waiter object.
Return type: botocore.waiter.Waiter

list_clusters(**kwargs)¶

Lists the Amazon EKS clusters in your AWS account in the specified Region.

See also: AWS API Documentation

Request Syntax

response = client.list_clusters(
    maxResults=123,
    nextToken='string'
)

Parameters

maxResults (integer) -- The maximum number of cluster results returned by ListClusters in paginated output. When this parameter is used, ListClusters only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListClusters request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListClusters returns up to 100 results and a nextToken value if applicable.
nextToken (string) --
The nextToken value returned from a previous paginated ListClusters request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value.

Note

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

Return type

dict

Returns

Response Syntax

{
    'clusters': [
        'string',
    ],
    'nextToken': 'string'
}

Response Structure

(dict) --
- clusters (list) --
  
  A list of all of the clusters for your account in the specified Region.
  - (string) --
- nextToken (string) --
  
  The nextToken value to include in a future ListClusters request. When the results of a ListClusters request exceed maxResults , this value can be used to retrieve the next page of results. This value is null when there are no more results to return.
