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, and .

The worker nodes and remaining workload setup are described in the topic.

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

Setting up an Infrastructure that uses ECS is similar to creating an , except that during creation, instead of selecting Enable EKS, you select Enable ECS Cluster.

For more information about ECS Services, see the documentation.

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 .

An AWS creates a private connection to supported AWS services and VPC endpoint services powered by AWS PrivateLink. Amazon VPC instances do not require public IP addresses to communicate with the resources of the service. Traffic between an Amazon VPC and a service does not leave the Amazon network.

VPC endpoints are virtual devices. They are horizontally scaled, redundant, and highly available Amazon VPC components that allow communication between instances in an Amazon VPC and services without imposing availability risks or bandwidth constraints on network traffic. There are two types of VPC endpoints, , and .

DuploCloud allows you to specify predefined AWS endpoints for your Infrastructure in the DuploCloud Portal.
