Enable Cluster Autoscaler for a Kubernetes cluster
The Cluster AutoScaler automatically adjusts the number of nodes in your cluster when Pods fail or are rescheduled onto other nodes.
In the DuploCloud Portal, navigate to Administrator -> Infrastructure. The Infrastructure page displays.
From the NAME column, select the Infrastructure with which you want to use Cluster AutoScaler.
Click the Settings tab.
Click Add. The Add Infra - Set Custom Data pane displays.
From the Setting Name list box, select Cluster Autoscaler.
Select Enable to enable EKS.
Click Set. Your configuration is displayed in the Settings tab.
Enable logging functionality for EKS
Follow the steps in the section Creating an Infrastructure. In the EKS Logging list box, select one or more ControlPlane Log types.
Enable EKS logging for an Infrastructure that you have already created.
In the DuploCloud Portal, navigate to Administrator -> Infrastructure.
From the NAME column, select the Infrastructure for which you want to enable EKS logging.
Click the Settings tab.
Click Add. The Infra - Set Custom Data pane displays.
From the Setting Name list box, select EKS ControlPlane Logs.
In the Setting Value field, enter: api;audit;authenticator;controllerManager;scheduler

Enable Elastic Kubernetes Service (EKS) for AWS by creating a DuploCloud Infrastructure
In the DuploCloud platform, a Kubernetes Cluster maps to a DuploCloud Infrastructure.
Start by creating a new Infrastructure in DuploCloud. When prompted to provide details for the new Infrastructure, select Enable EKS. In the EKS Version field, select the desired release.
Optionally, enable logging and custom EKS endpoints.
The worker nodes and remaining workload setup are described in the Tenant topic.
Up to one instance (0 or 1) of an EKS is supported for each DuploCloud Infrastructure.
Creating an Infrastructure with EKS can take some time. See the Infrastructure section for details about other elements on the Add Infrastructure form.
When the Infrastructure is in the ready state, as indicated by a Complete status, navigate to Kubernetes -> Services and select the Infrastructure from the NAME column to view the Kubernetes configuration details, including the token and configuration for kubectl.
When you create Tenants in an Infrastructure, a namespace is created in the Kubernetes cluster with the name duploservices-TENANT_NAME
Specify EKS endpoints for an Infrastructure
AWS SDKs and the AWS Command Line Interface (AWS CLI) automatically use the default public endpoint for each service in an AWS Region. However, when you create an Infrastructure in DuploCloud, you can specify a custom Private endpoint, a custom Public endpoint, or Both public and private custom endpoints. If you specify no endpoints, the default Public endpoint is used.
For more information about AWS Endpoints, see the .
Follow the steps in the section . Before clicking Create, specify EKS Endpoint Visibility.
From the EKS Endpoint Visibility list box, select Public, Private, or Both public and private. If you select private or Both public and private, the Allow VPN Access to the EKS Cluster option is enabled.
Click Advanced Options.
Using the Private Subnet CIDR and Public Subnet CIDR fields, specify CIDRs for alternate public and private endpoints.
Click Create.
In the DuploCloud Portal, navigate to Administrator -> Infrastructure. The Infrastructure page displays.
From the NAME column, select the Infrastructure.
Click the Settings tab.
From the Setting Name list box, select Enable VPN Access to EKS Cluster.
Select Enable to enable VPN.
Modifying endpoints can incur an outage of up to thirty (30) minutes in your EKS cluster. Plan your update accordingly to minimize disruption for your users.
To modify the visibility for EKS endpoints you have already created:
In the DuploCloud Portal, navigate to Administrator -> Infrastructure. The Infrastructure page displays.
From the Name column, select the Infrastructure for which you want to modify EKS endpoints.
Click the Settings tab.
From the Setting Value list box, select the desired type of visibility for endpoints (private, public, or both).
Click Set.
To change VPN visibility from public to private after you have , follow these steps.
In the EKS Endpoint Visibility row, in the Actions column, click the ( ) icon and select Update Setting. The Infra - Set Custom Data pane displays.
Click Set. When you , the Allow VPN Access to the EKS Cluster option will be enabled.
In the EKS Endpoint Visibility row, in the Actions column, click the ( ) icon and select Update Setting. The Infra - Set Custom Data pane displays.
