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
DescribeUpdate"/>.
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
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.
You can also use this API operation to choose different subnets and security groups for the cluster. You must specify at least two subnets that are in different Availability Zones. You can't change which VPC the subnets are from, the subnets must be in the same VPC as the subnets that the cluster was created with. For more information about the VPC requirements, see
https://docs.aws.amazon.com/eks/latest/userguide/network_reqs.html in the
Amazon EKS User Guide.
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.
