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

For information on configuring your AWS environment for Chef InSpec and creating an InSpec profile that uses the InSpec AWS resource pack, see the Chef InSpec documentation on the AWS cloud platform.

Syntax

An aws_elasticache_cluster resource block declares the tests for a single AWS ElastiCache cluster by cache_cluster_id.

describe aws_elasticache_cluster(cache_cluster_id: 'my-cluster-123') do
  it { should exist }
end

The value of the cache_cluster_id can be provided as a string.

describe aws_elasticache_cluster('my-cluster-123') do
  its('engine') { should cmp 'redis' }
end

Parameters

The ElastiCache cluster ID must be provided.

cache_cluster_id (required)

The ID of the ElastiCache cluster:

• contains between 1 and 50 alphanumeric characters or hyphens,
• should start with a letter,
• cannot end with a hyphen or contain two consecutive hyphens.

It can be passed either as a string or as a cache_cluster_id: 'value' key-value entry in a hash.

Properties

cache_cluster_id

The user-supplied identifier of the cluster. This identifier is a unique key that identifies a cluster.

engine

The name of the cache engine, e.g. redis.

node_ids

The id list of all cluster nodes.

ports

A hash of the node ID and port number pairs.

status

The current state of the cluster, e.g. creating, available.

encrypted_at_rest

Indicates whether the content is encrypted at rest or not.

encrypted_at_transit

Indicates whether the content is encrypted at transit or not.

There are also additional properties available. For a comprehensive list, see the API reference documentation.

Examples

Test that an ElastiCache cluster is available.

describe aws_elasticache_cluster("my-cluster-123") do
    its("status") { should eq 'available' }
end

Test that an Elasticache cluster engine is listening on port 11211.

describe aws_elasticache_cluster(cache_cluster_id: "my-cluster-123") do
    its("port") { should cmp 11211 }
end

Test that an Elasticache cluster’s engine version is 1.5.16.

describe aws_elasticache_cluster(cache_cluster_id: "my-cluster-123") do
    its("engine_version") { should cmp 1.5.16 }
end
