How to Import an AWS VPC Endpoint into Terraform

Import AWS VPC Endpoint with Terraback (recommended)

Terraback reverse-engineers your live infrastructure: it reads the Amazon VPC resource with read-only credentials, generates the HCL, and produces the exact import block. Two commands take you from a live AWS VPC Endpoint to managed Terraform.

terraback scan all aws --region us-east-1

terraback aws import --method bulk

The Terraform import block

Terraback emits a Terraform 1.5+ import block like the one below. Because the block lives in your configuration, the import is reviewable in a pull request and repeatable across environments.

import {
  to = aws_vpc_endpoint.s3
  id = "vpce-0a1b2c3d4e5f6a7b8"
}

Example aws_vpc_endpoint configuration

Here is a realistic AWS VPC Endpoint block. Terraback generates a fuller version from your actual resource attributes; this is a minimal, valid starting point.

resource "aws_vpc_endpoint" "s3" {
  vpc_id            = "vpc-0a1b2c3d4e5f6a7b8"
  service_name      = "com.amazonaws.us-east-1.s3"
  vpc_endpoint_type = "Gateway"
  route_table_ids   = ["rtb-0a1b2c3d4e5f6a7b8"]
}

Gotchas when importing a AWS VPC Endpoint

• Import by the vpce- ID.
• Gateway endpoints use route_table_ids while Interface and GatewayLoadBalancer endpoints use subnet_ids and security_group_ids; copy only the fields valid for the endpoint type.
• Route table and subnet associations can also be expressed as separate aws_vpc_endpoint_route_table_association / aws_vpc_endpoint_subnet_association resources; do not mix the two styles.
• private_dns_enabled applies only to Interface endpoints; setting it on a Gateway endpoint is invalid.

Doing it manually with terraform import

The native approach is to write the aws_vpc_endpoint block by hand, then run terraform import aws_vpc_endpoint.example <import-id> for every resource, one at a time. That works for a handful of resources, but it does not scale: you author all the HCL yourself and repeat the command for each item. Terraback generates the HCL and the import blocks for your whole account in one pass.
