## Synopsis

- Manage cache clusters in Amazon Elasticache.

- Returns information about the specified cache cluster.

## Requirements

The below requirements are needed on the host that executes this module.

- boto

- boto3

- python >= 2.6

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
aws_access_key string |  | AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used. aliases: ec2_access_key, access_key
aws_secret_key string |  | AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used. aliases: ec2_secret_key, secret_key
cache_engine_version - |  | The version number of the cache engine
cache_parameter_group - |  | The name of the cache parameter group to associate with this cache cluster. If this argument is omitted, the default cache parameter group for the specified engine will be used. aliases: parameter_group
cache_port - |  | The port number on which each of the cache nodes will accept connections
cache_security_groups - |  | A list of cache security group names to associate with this cache cluster. Must be an empty list if inside a vpc
cache_subnet_group - |  | The subnet group name to associate with. Only use if inside a vpc. Required if inside a vpc

debug_botocore_endpoint_logs
boolean
added in 2.8

Choices:
- no ←
- yes

Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.

ec2_url string |  | Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.

engine
-

Choices:
- redis
- memcached ←

Name of the cache engine to be used.

hard_modify
boolean

Choices:
- no ←
- yes

Whether to destroy and recreate an existing cache cluster if necessary in order to modify its state

name - / required |  | The cache cluster identifier
node_type - | Default: "cache.m1.small" | The compute and memory capacity of the nodes in the cache cluster
num_nodes - |  | The initial number of cache nodes that the cache cluster will have. Required when state=present.
profile string |  | Uses a boto profile. Only works with boto >= 2.24.0.
region string |  | The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region aliases: aws_region, ec2_region
security_group_ids - |  | A list of vpc security group IDs to associate with this cache cluster. Only use if inside a vpc
security_token string |  | AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token

state
- / required

Choices:
- present
- absent
- rebooted

`absent` or `present` are idempotent actions that will create or destroy a cache cluster as needed. `rebooted` will reboot the cluster, resulting in a momentary outage.

validate_certs
boolean

Choices:
- no
- yes ←

When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

wait
boolean

Choices:
- no
- yes ←

Wait for cache cluster result before returning

zone - |  | The EC2 Availability Zone in which the cache cluster will be created

## Notes

Note

- If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence `AWS_URL` or `EC2_URL`, `AWS_ACCESS_KEY_ID` or `AWS_ACCESS_KEY` or `EC2_ACCESS_KEY`, `AWS_SECRET_ACCESS_KEY` or `AWS_SECRET_KEY` or `EC2_SECRET_KEY`, `AWS_SECURITY_TOKEN` or `EC2_SECURITY_TOKEN`, `AWS_REGION` or `EC2_REGION`

- Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html

- `AWS_REGION` or `EC2_REGION` can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file

## Examples

    # Note: None of these examples set aws_access_key, aws_secret_key, or region.
    # It is assumed that their matching environment variables are set.

    # Basic example
    - elasticache:
        name: "test-please-delete"
        state: present
        engine: memcached
        cache_engine_version: 1.4.14
        node_type: cache.m1.small
        num_nodes: 1
        cache_port: 11211
        cache_security_groups:
          - default
        zone: us-east-1d

    # Ensure cache cluster is gone
    - elasticache:
        name: "test-please-delete"
        state: absent

    # Reboot cache cluster
    - elasticache:
        name: "test-please-delete"
        state: rebooted
