Solution for "Error: multiple VPC Endpoint Services matched"

[antonbabenko]

If you have been using this VPC module and started from 2.2.2021 started seeing the error: Error: multiple VPC Endpoint Services matched; use additional constraints to reduce matches to a single VPC Endpoint Service, here are the available solutions depending on the versions you use:

Terraform 0.12, 0.13, 0.14:

1. Upgrade Terraform AWS provider to be 3.10.0 (see changelog for the release) or newer:

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = ">= 3.10"
    }
  }
}

2. Upgrade version of the module to be 2.70.0 (or newer):

module "vpc" {
  source  = "terraform-aws-modules/vpc/aws"
  version = "2.70.0"

  # ...
}

3. Alternatively, if you can't upgrade Terraform AWS provider as described in the first point, you can use this module version 2.69.0:

module "vpc" {
  source  = "terraform-aws-modules/vpc/aws"
  version = "2.69.0"

  # ...
}

Terraform 0.11

You can upgrade your configuration to use v1.73.0 to get the specified issue fixed on Terraform 0.11 (commit):

module "vpc" {
  source  = "terraform-aws-modules/vpc/aws"
  version = "1.73.0"

  # ...
}

Notes

If you want to manage the VPC endpoint for S3 outside of this module (when using Terraform 0.11, for eg), you can set enable_s3_endpoint = false and create resources aws_vpc_endpoint externally.
