Class: Aws::EKS::Client

Inherits:
Seahorse::Client::Base show all
Defined in:
(unknown)

Overview

An API client for Amazon Elastic Kubernetes Service. To construct a client, you need to configure a :region and :credentials.

eks = Aws::EKS::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

See #initialize for a full list of supported configuration options.

Region

You can configure a default region in the following locations:

  • ENV['AWS_REGION']
  • Aws.config[:region]

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

  • ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY']
  • Aws.config[:credentials]
  • The shared credentials ini file at ~/.aws/credentials (more information)
  • From an instance profile when running on EC2

You can also construct a credentials object from one of the following classes:

Alternatively, you configure credentials with :access_key_id and :secret_access_key:

# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))

Aws::EKS::Client.new(
  access_key_id: creds['access_key_id'],
  secret_access_key: creds['secret_access_key']
)

Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

Instance Method Details

#create_cluster(options = {}) ⇒ 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.

#delete_cluster(options = {}) ⇒ 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 attached to the cluster, you must delete them first. For more information, see DeleteNodegroup.

#update_cluster_config(options = {}) ⇒ 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({

#update_nodegroup_version(options = {}) ⇒ 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.

    The name of the Amazon EKS cluster that is associated with the managed node group to update.

  • :nodegroup_name (required, String)

    The name of the managed node group to update.

  • :version (String)

    The Kubernetes version to update to. If no version is specified, then the Kubernetes version of the node group does not change. You can specify the Kubernetes version of the cluster to update the node group to the latest AMI version of the cluster\'s Kubernetes version.

  • :release_version (String)

    The AMI version of the Amazon EKS-optimized AMI to use for the update. By default, the latest available AMI version for the node group\'s Kubernetes version is used. For more information, see Amazon EKS-Optimized Linux AMI Versions in the Amazon EKS User Guide.

  • :force (Boolean)

    Force the update if the existing node group\'s pods are unable to be drained due to a pod disruption budget issue. If a previous update fails because pods could not be drained, you can force the update after it fails to terminate the old node regardless of whether or not any pods are running on the node.

  • :client_request_token (String)

    This parameter will be auto-filled on your behalf with a random UUIDv4 when no value is provided. Unique, case-sensitive identifier that you provide to ensure the idempotency of the request.

Returns:

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

Waiters polls an API operation until a resource enters a desired state.

Basic Usage

Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.

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

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You configure waiters by passing a block to #wait_until:

# poll for ~25 seconds
client.wait_until(...) do |w|
  w.max_attempts = 5
  w.delay = 5
end

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(...) do |w|

  # disable max attempts
  w.max_attempts = nil

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

end

Handling Errors

When a waiter is successful, it returns true. When a waiter fails, it raises an error. All errors raised extend from Waiters::Errors::WaiterFailed.

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

Parameters:

  • waiter_name (Symbol)

    The name of the waiter. See #waiter_names for a full list of supported waiters.

  • params (Hash) (defaults to: {})

    Additional request parameters. See the #waiter_names for a list of supported waiters and what request they call. The called request determines the list of accepted parameters.

Yield Parameters:

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.
