aws_elasticache_clusters Resource

[edit on GitHub]

Use the aws_elasticache_clusters InSpec audit resource to test the properties of all AWS ElastiCache clusters. To audit a single ElastiCache cluster, use aws_elasticache_cluster (singular).

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

An aws_elasticache_clusters resource block collects a group of ElastiCache cluster descriptions and then tests that group.

describe aws_elasticache_clusters
  it { should exist }
end   

Parameters

This resource does not require any parameters.

Properties

ids

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

node_types

The name of the compute and memory capacity node type for the cluster, e.g. cache.m5.large.

engines

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

status

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

zones

The name of the availability zone in which the cluster is located or “Multiple” if the cache nodes are located in different availability zones.

subnet_group_names

The name of the cache subnet group.

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.

Examples

Ensure that exactly 3 ElastiCache clusters exist.

describe aws_elasticache_clusters do
  its("entries.count") { should cmp 3 }
end

Use this InSpec resource to request the IDs of all ElastiCache clusters, then test in-depth using aws_elasticache_cluster and aws_elasticache_cluster_node.

aws_elasticache_clusters.ids.each do |id|
  aws_elasticache_cluster(id).node_ids.each do |node_id|
    describe aws_elasticache_cluster_node(cache_cluster_id: id, node_id: node_id) do
      it { should exist }
    end
  end
end

Matchers

This InSpec audit resource has the following 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_elasticache_clusters.where( <property>: <value>) do
  it { should exist }
end

describe aws_elasticache_clusters.where( <property>: <value>) do
  it { should_not exist }
end

AWS Permissions

Your Principal will need the ElastiCache:Client:CacheClusterMessage action with Effect set to Allow.

You can find detailed documentation at Actions, Resources, and Condition Keys for Amazon ElastiCache, and Actions, Resources, and Condition Keys for Identity And Access Management.
