aws_vpc_endpoints Resource

[edit on GitHub]

Use the aws_vpc_endpoints InSpec audit resource to test properties of some or all AWS VPC Endpoints.

VPC Endpoints can be of two types: ‘Gateway’ and ‘Interface’.

A Gateway type VPC endpoint accepts a route-table whereas an Interface type VPC endpoint takes one or more subnets and one or more security groups. Hence their properties might differ based on the type.

For additional information, including details on parameters and properties, see the AWS documentation on VPC Endpoints.

Installation

This resource is available in the Chef InSpec AWS resource pack.

See the Chef InSpec documentation on cloud platforms for information on configuring your AWS environment for InSpec and creating an InSpec profile that uses the InSpec AWS resource pack.

Syntax

Ensure that one or more VPC Endpoints exist.

describe aws_vpc_endpoints do
  it { should exist }
end

An aws_vpc_endpoints resource block uses an optional filter to select a group of VPC Endpoints and then tests that group.

Parameters

This resource does not require any parameters.

Examples

Ensure a VPC has VPC Endpoints.

describe aws_vpc_endpoints.where( vpc_id: vpc-12345678 )
  it { should exist }
end

Match count of VPC Endpoints of Gateway type in a particular VPC.

describe aws_vpc_endpoints.where( vpc_id: vpc-12345678 ).where(vpc_endpoint_type: "Gateway") do
    its('count') { should eq 4 }
end

Check tags .

describe aws_vpc_endpoints do
  its('tags') { should include(:Environment => 'env-name',
                               :Name => 'vpce-name')}
end
