aws_cloudformation_stack resource

Use the aws_cloudformation_stack InSpec audit resource to test properties of a single AWS Cloud Formation Stack.

Syntax

Ensure that an aws_cloudformation_stack exists

describe aws_cloudformation_stack('stack-name') do
  it { should exist }
end

describe aws_cloudformation_stack(stack_name: 'stack-name') do
  it { should exist }
end

Parameters

stack_name (required)

This resource accepts a single parameter, the CloudFormation Stack name which uniquely identifies the stack. This can be passed either as a string or as a stack_name: 'value' key-value entry in a hash.

Examples

Test that a CloudFormation Stack has its stack_status configured correctly

describe aws_cloudformation_stack('stack_name') do
its ('stack_status')  { should eq 'CREATE_COMPLETE' }
end

Matchers

This InSpec audit resource has no special matchers. For a full list of available matchers, please visit our Universal Matchers page.

exist

The control will pass if the describe returns at least one result.

Use should_not to test the entity should not exist.

describe aws_cloudformation_stack('AnExistingStack') do
  it { should exist }
end

describe aws_cloudformation_stack('ANonExistentStack') do
  it { should_not exist }
end

AWS Permissions

Your Principal will need the cloudformation:DescribeStacks action set to Allow.

You can find detailed documentation at Authentication and Access Control for CloudFormation
