Parameters:

  • options (Hash)

Options Hash (options):

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::SharedCredentials - Used for loading credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]

Instance Method Details

#create_cluster(params = {}) ⇒ Types::CreateClusterResponse

Creates an Amazon EKS control plane.

The Amazon EKS control plane consists of control plane instances that run the Kubernetes software, such as 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. Each Amazon EKS cluster control plane is single-tenant and unique and runs on its own set of Amazon EC2 instances.

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).

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.

You can use the endpointPublicAccess and endpointPrivateAccess parameters to enable or disable public and private access to your cluster's Kubernetes API server endpoint. By default, public access is enabled, and private access is disabled. For more information, see Amazon EKS Cluster Endpoint Access Control in the Amazon EKS User Guide .

You can use the logging parameter to enable or disable exporting the Kubernetes control plane logs for your cluster to CloudWatch Logs. By default, cluster control plane logs aren't exported to CloudWatch Logs. For more information, see Amazon EKS Cluster Control Plane Logs in the Amazon EKS User Guide .

CloudWatch Logs ingestion, archive storage, and data scanning rates apply to exported control plane logs. For more information, see Amazon CloudWatch Pricing.

Cluster creation typically takes between 10 and 15 minutes. 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.

#create_fargate_profile(params = {}) ⇒ Types::CreateFargateProfileResponse

Creates an AWS Fargate profile for your Amazon EKS cluster. You must have at least one Fargate profile in a cluster to be able to run pods on Fargate.

The Fargate profile allows an administrator to declare which pods run on Fargate and specify which pods run on which Fargate profile. This declaration is done through the profile’s selectors. Each profile can have up to five selectors that contain a namespace and labels. A namespace is required for every selector. The label field consists of multiple optional key-value pairs. Pods that match the selectors are scheduled on Fargate. If a to-be-scheduled pod matches any of the selectors in the Fargate profile, then that pod is run on Fargate.

When you create a Fargate profile, you must specify a pod execution role to use with the pods that are scheduled with the profile. This role is added to the cluster's Kubernetes Role Based Access Control (RBAC) for authorization so that the kubelet that is running on the Fargate infrastructure can register with your Amazon EKS cluster so that it can appear in your cluster as a node. The pod execution role also provides IAM permissions to the Fargate infrastructure to allow read access to Amazon ECR image repositories. For more information, see Pod Execution Role in the Amazon EKS User Guide.

Fargate profiles are immutable. However, you can create a new updated profile to replace an existing profile and then delete the original after the updated profile has finished creating.

If any Fargate profiles in a cluster are in the DELETING status, you must wait for that Fargate profile to finish deleting before you can create any other profiles in that cluster.

For more information, see AWS Fargate Profile in the Amazon EKS User Guide.

Options Hash (params):

  • :fargate_profile_name (required, String) —

    The name of the Fargate profile.

  • :cluster_name (required, String) —

    The name of the Amazon EKS cluster to apply the Fargate profile to.

  • :pod_execution_role_arn (required, String) —

    The Amazon Resource Name (ARN) of the pod execution role to use for pods that match the selectors in the Fargate profile. The pod execution role allows Fargate infrastructure to register with your cluster as a node, and it provides read access to Amazon ECR image repositories. For more information, see Pod Execution Role in the Amazon EKS User Guide.

  • :subnets (Array<String>) —

    The IDs of subnets to launch your pods into. At this time, pods running on Fargate are not assigned public IP addresses, so only private subnets (with no direct route to an Internet Gateway) are accepted for this parameter.

  • :selectors (Array<Types::FargateProfileSelector>) —

    The selectors to match for pods to use this Fargate profile. Each selector must have an associated namespace. Optionally, you can also specify labels for a namespace. You may specify up to five selectors in a Fargate profile.

  • :client_request_token (String) —

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

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :tags (Hash<String,String>) —

    The metadata to apply to the Fargate profile to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define. Fargate profile tags do not propagate to any other resources associated with the Fargate profile, such as the pods that are scheduled with it.

#create_nodegroup(params = {}) ⇒ Types::CreateNodegroupResponse

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.

  • :remote_access (Types::RemoteAccessConfig) —

    The remote access (SSH) configuration to use with your node group.

  • :node_role (required, String) —

    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 .

  • :labels (Hash<String,String>) —

    The Kubernetes labels to be applied to the nodes in the node group when they are created.

  • :tags (Hash<String,String>) —

    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.

  • :client_request_token (String) —

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

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :version (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.

  • :release_version (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.

#delete_cluster(params = {}) ⇒ Types::DeleteClusterResponse

Deletes the Amazon EKS cluster control plane.

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.

If you have managed node groups or Fargate profiles attached to the cluster, you must delete them first. For more information, see DeleteNodegroup and DeleteFargateProfile.

Examples:

Example: To delete a cluster


# This example command deletes a cluster named `devel` in your default region.

resp = client.delete_cluster({
  name: "devel",

#delete_fargate_profile(params = {}) ⇒ Types::DeleteFargateProfileResponse

Deletes an AWS Fargate profile.

When you delete a Fargate profile, any pods running on Fargate that were created with the profile are deleted. If those pods match another Fargate profile, then they are scheduled on Fargate with that profile. If they no longer match any Fargate profiles, then they are not scheduled on Fargate and they may remain in a pending state.

Only one Fargate profile in a cluster can be in the DELETING status at a time. You must wait for a Fargate profile to finish deleting before you can delete any other profiles in that cluster.

Examples:

#list_clusters(params = {}) ⇒ Types::ListClustersResponse

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

The returned response is a pageable response and is Enumerable. For details on usage see PageableResponse.

Examples:

Example: To list your available clusters


# This example command lists all of your available clusters in your default region.

resp = client.list_clusters({
})

resp.to_h outputs the following:
{
  clusters: [
    "devel", 
    "prod", 
  ], 
}

Request syntax with placeholder values


resp = client.list_clusters({
  max_results: 1,
  next_token: "String",
})

Response structure


resp.clusters #=> Array
resp.clusters[0] #=> String
resp.next_token #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :max_results (Integer) —

    The maximum number of cluster results returned by ListClusters in paginated output. When you use this parameter, ListClusters returns only maxResults results in a single page along with a nextToken response element. You can see the remaining results of the initial request by sending another ListClusters request with the returned nextToken value. This value can be between 1 and 100. If you don't use this parameter, ListClusters returns up to 100 results and a nextToken value if applicable.

  • :next_token (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.

#update_cluster_config(params = {}) ⇒ Types::UpdateClusterConfigResponse

Updates an Amazon EKS cluster configuration. Your cluster continues to function during the update. The response output includes an update ID that you can use to track the status of your cluster update with the DescribeUpdate API operation.

You can use this API operation to enable or disable exporting the Kubernetes control plane logs for your cluster to CloudWatch Logs. By default, cluster control plane logs aren't exported to CloudWatch Logs. For more information, see Amazon EKS Cluster Control Plane Logs in the Amazon EKS User Guide .

CloudWatch Logs ingestion, archive storage, and data scanning rates apply to exported control plane logs. For more information, see Amazon CloudWatch Pricing.

You can also use this API operation to enable or disable public and private access to your cluster's Kubernetes API server endpoint. By default, public access is enabled, and private access is disabled. For more information, see Amazon EKS Cluster Endpoint Access Control in the Amazon EKS User Guide .

At this time, you can not update the subnets or security group IDs for an existing cluster.

Cluster updates are asynchronous, and they should finish within a few minutes. During an update, the cluster status moves to UPDATING (this status transition is eventually consistent). When the update is complete (either Failed or Successful), the cluster status moves to Active.

Examples:

Request syntax with placeholder values


resp = client.update_cluster_config({
  name: "String", # required
  resources_vpc_config: {
    subnet_ids: ["String"],

#update_cluster_version(params = {}) ⇒ Types::UpdateClusterVersionResponse

Updates an Amazon EKS cluster to the specified Kubernetes version. Your cluster continues to function during the update. The response output includes an update ID that you can use to track the status of your cluster update with the DescribeUpdate API operation.

Cluster updates are asynchronous, and they should finish within a few minutes. During an update, the cluster status moves to UPDATING (this status transition is eventually consistent). When the update is complete (either Failed or Successful), the cluster status moves to Active.

If your cluster has managed node groups attached to it, all of your node groups’ Kubernetes versions must match the cluster’s Kubernetes version in order to update the cluster to a new Kubernetes version.

#update_nodegroup_version(params = {}) ⇒ Types::UpdateNodegroupVersionResponse

Updates the Kubernetes version or AMI version of an Amazon EKS managed node group.

You can update to the latest available AMI version of a node group's current Kubernetes version by not specifying a Kubernetes version in the request. You can update to the latest AMI version of your cluster's current Kubernetes version by specifying your cluster's Kubernetes version in the request. For more information, see Amazon EKS-Optimized Linux AMI Versions in the Amazon EKS User Guide.

You cannot roll back a node group to an earlier Kubernetes version or AMI version.

When a node in a managed node group is terminated due to a scaling action or update, the pods in that node are drained first. Amazon EKS attempts to drain the nodes gracefully and will fail if it is unable to do so. You can force the update if Amazon EKS is unable to drain the nodes as a result of a pod disruption budget issue.

Examples:

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean

Polls an API operation until a resource enters a desired state.

Basic Usage

A waiter will call an API operation until:

  • It is successful
  • It enters a terminal state
  • It makes the maximum number of attempts

In between attempts, the waiter will sleep.

# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.

# poll for ~25 seconds
client.wait_until(waiter_name, params, {
  max_attempts: 5,
  delay: 5,
})

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(waiter_name, params, {

  # disable max attempts
  max_attempts: nil,

  # poll for 1 hour, instead of a number of attempts
  before_wait: -> (attempts, response) do
    throw :failure if Time.now - started_at > 3600
  end
})

Handling Errors

When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

Valid Waiters

The following table lists the valid waiter names, the operations they call, and the default :delay and :max_attempts values.

waiter_name params :delay :max_attempts
cluster_active #describe_cluster 30 40
cluster_deleted #describe_cluster 30 40
nodegroup_active #describe_nodegroup 30 80
nodegroup_deleted #describe_nodegroup 30 40

Parameters:

  • waiter_name (Symbol)
  • params (Hash) (defaults to: {}) —

    ({})

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :max_attempts (Integer)
  • :delay (Integer)
  • :before_attempt (Proc)
  • :before_wait (Proc)

Yields:

  • (w.waiter)

Returns:

  • (Boolean) —

    Returns true if the waiter was successful.

Raises:

  • (Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError) —

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError) —

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError) —

    Raised when you request to wait for an unknown state.
