describe-cluster

Description

Describes an Amazon EKS cluster.

The API server endpoint and certificate authority data returned by this operation are required for kubelet and kubectl to communicate with your Kubernetes API server. For more information, see Creating or updating a ``kubeconfig` file for an Amazon EKS cluster <https://docs.aws.amazon.com/eks/latest/userguide/create-kubeconfig.html>`__ .

Note

The API server endpoint and certificate authority data aren't available until the cluster reaches the ACTIVE state.

Options

--name (string)

The name of your cluster.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

roleArn -> (string)

The Amazon Resource Name (ARN) of the IAM role that provides permissions for the Kubernetes control plane to make calls to Amazon Web Services API operations on your behalf.

resourcesVpcConfig -> (structure)

The VPC configuration 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 .

subnetIds -> (list)

The subnets associated with your cluster.

(string)

securityGroupIds -> (list)

The security groups associated with the cross-account elastic network interfaces that are used to allow communication between your nodes and the Kubernetes control plane.

(string)

clusterSecurityGroupId -> (string)

The cluster security group that was created by Amazon EKS for the cluster. Managed node groups use this security group for control-plane-to-data-plane communication.

vpcId -> (string)

The VPC associated with your cluster.

endpointPublicAccess -> (boolean)

Whether the public API server endpoint is enabled.

endpointPrivateAccess -> (boolean)

This parameter indicates whether the Amazon EKS private API server endpoint is enabled. If the Amazon EKS private API server endpoint is enabled, Kubernetes API requests that originate from within your cluster's VPC use the private VPC endpoint instead of traversing the internet. If this value is disabled and you have nodes or Fargate pods in the cluster, then ensure that publicAccessCidrs includes the necessary CIDR blocks for communication with the nodes or Fargate pods. For more information, see Amazon EKS cluster endpoint access control in the * Amazon EKS User Guide * .

publicAccessCidrs -> (list)

The CIDR blocks that are allowed access to your cluster's public Kubernetes API server endpoint.

(string)

kubernetesNetworkConfig -> (structure)

The Kubernetes network configuration for the cluster.

serviceIpv4Cidr -> (string)

The CIDR block that Kubernetes Pod and Service object IP addresses are assigned from. Kubernetes assigns addresses from an IPv4 CIDR block assigned to a subnet that the node is in. If you didn't specify a CIDR block when you created the cluster, then Kubernetes assigns addresses from either the 10.100.0.0/16 or 172.20.0.0/16 CIDR blocks. If this was specified, then it was specified when the cluster was created and it can't be changed.

serviceIpv6Cidr -> (string)

The CIDR block that Kubernetes pod and service IP addresses are assigned from if you created a 1.21 or later cluster with version 1.10.1 or later of the Amazon VPC CNI add-on and specified ipv6 for ipFamily when you created the cluster. Kubernetes assigns service addresses from the unique local address range (fc00::/7 ) because you can't specify a custom IPv6 CIDR block when you create the cluster.

ipFamily -> (string)

The IP family used to assign Kubernetes Pod and Service objects IP addresses. The IP family is always ipv4 , unless you have a 1.21 or later cluster running version 1.10.1 or later of the Amazon VPC CNI plugin for Kubernetes and specified ipv6 when you created the cluster.

The logging configuration for your cluster.

clusterLogging -> (list)

The cluster control plane logging configuration for your cluster.

(structure)

An object representing the enabled or disabled Kubernetes control plane logs for your cluster.

types -> (list)

The available cluster control plane log types.

(string)

enabled -> (boolean)

If a log type is enabled, that log type exports its control plane logs to CloudWatch Logs. If a log type isn't enabled, that log type doesn't export its control plane logs. Each individual log type can be enabled or disabled independently.

identity -> (structure)

The identity provider information for the cluster.

clientRequestToken -> (string)

A unique, case-sensitive identifier that you provide to ensure the idempotency of the request.

platformVersion -> (string)

The platform version of your Amazon EKS cluster. For more information about clusters deployed on the Amazon Web Services Cloud, see Platform versions in the * Amazon EKS User Guide * . For more information about local clusters deployed on an Outpost, see Amazon EKS local cluster platform versions in the * Amazon EKS User Guide * .

tags -> (map)

Metadata that assists with categorization and organization. Each tag consists of a key and an optional value. You define both. Tags don't propagate to any other cluster or Amazon Web Services resources.

key -> (string)

One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

value -> (string)

The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

encryptionConfig -> (list)

The encryption configuration for the cluster.

(structure)
