EC2 Image Builder and interface VPC endpoints (AWS PrivateLink)

You can establish a private connection between your VPC and EC2 Image Builder by creating an interface VPC endpoint. Interface endpoints are powered by AWS PrivateLink, a technology that enables you to privately access Image Builder APIs without an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Instances in your VPC don't need public IP addresses to communicate with Image Builder APIs. Traffic between your VPC and Image Builder does not leave the Amazon network.

Each interface endpoint is represented by one or more Elastic Network Interfaces in your subnets.

For more information, see Interface VPC endpoints (AWS PrivateLink) in the Amazon VPC User Guide.

Considerations for Image Builder VPC endpoints

Before you set up an interface VPC endpoint for Image Builder, ensure that you review Interface endpoint properties and limitations in the Amazon VPC User Guide.

Image Builder supports making calls to all of its API actions from your VPC.

Creating an interface VPC endpoint for Image Builder

You can create a VPC endpoint for the Image Builder service using either the Amazon VPC console or the AWS Command Line Interface (AWS CLI). For more information, see Creating an interface endpoint in the Amazon VPC User Guide.

Create a VPC endpoint for Image Builder using the following service name:

If you enable private DNS for the endpoint, you can make API requests to Image Builder using its default DNS name for the Region, for example, imagebuilder.us-east-1.amazonaws.com. To look up the endpoint that applies to your target Region, see EC2 Image Builder endpoints and quotas in the Amazon Web Services General Reference.

For more information, see Accessing a service through an interface endpoint in the Amazon VPC User Guide.

Creating a VPC endpoint policy for Image Builder

You can attach an endpoint policy to your VPC endpoint that controls access to Image Builder. The policy specifies the following information:

For more information, see Controlling access to services with VPC endpoints in the Amazon VPC User Guide.

Example: VPC endpoint policy for Image Builder actions

The following is an example of an endpoint policy for Image Builder that denies permission to delete Image Builder images and components. The example policy also grants permission to perform all other EC2 Image Builder actions.
