aws_route_table

Use the aws_route_table InSpec audit resource to test properties of a single Route Table. A route table contains a set of rules, called routes, that are used to determine where network traffic is directed.

Syntax

This resource expects a single parameter that uniquely identifies the Route Table. You may pass it as a string, or as the value in a hash:

describe aws_route_table('rtb-123abcde') do
  it { should exist }
end

describe aws_route_table(route_table_id: 'rtb-123abcde') do
  it { should exist }
end

Parameters

route_table_id (required)

This resource accepts a single parameter, the route_table_id. This can be passed either as a string or as a route_table_id: 'value' key-value entry in a hash.

See also the AWS documentation on Route Tables.
