Manage Elasticache
==================
.. versionadded:: 2014.7.0
Create, destroy and update Elasticache clusters. Be aware that this interacts
with Amazon's services, and so may incur charges.
Note: This module currently only supports creation and deletion of
elasticache resources and will not modify clusters when their configuration
changes in your state files.
This module uses ``boto``, which can be installed via package, or pip.
This module accepts explicit elasticache credentials but can also utilize
IAM roles assigned to the instance through Instance Profiles. Dynamic
credentials are then automatically obtained from AWS API and no further
configuration is necessary. More information available `here
<http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html>`_.
If IAM roles are not used you need to specify them either in a pillar file or
in the minion's config file:
.. code-block:: yaml
elasticache.keyid: GKTADJGHEIQSXMKKRBJ08H
elasticache.key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
It's also possible to specify ``key``, ``keyid`` and ``region`` via a profile, either
passed in as a dict, or as a string to pull from pillars or minion config:
.. code-block:: yaml
myprofile:
keyid: GKTADJGHEIQSXMKKRBJ08H
key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
region: us-east-1
.. code-block:: yaml

boto_elasticache.present:
- name: myelasticache
- engine: redis
- cache_node_type: cache.t1.micro

Ensure the cache cluster exists.
name
Name of the cache cluster (cache cluster id).
engine
The name of the cache engine to be used for this cache cluster. Valid
values are memcached or redis.
cache_node_type
The compute and memory capacity of the nodes in the cache cluster.
cache.t1.micro, cache.m1.small, etc. See: https://boto.readthedocs.io/en/latest/ref/elasticache.html#boto.elasticache.layer1.ElastiCacheConnection.create_cache_cluster
num_cache_nodes
The number of cache nodes that the cache cluster will have.
preferred_availability_zone
The EC2 Availability Zone in which the cache cluster will be created.
All cache nodes belonging to a cache cluster are placed in the
preferred availability zone.
port
The port number on which each of the cache nodes will accept
connections.
cache_parameter_group_name
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.
cache_security_group_names
A list of cache security group names to associate with this cache
cluster. Use this parameter only when you are creating a cluster
outside of a VPC.
replication_group_id
The replication group to which this cache cluster should belong. If
this parameter is specified, the cache cluster will be added to the
specified replication group as a read replica; otherwise, the cache
cluster will be a standalone primary that is not part of any
replication group.
auto_minor_version_upgrade
Determines whether minor engine upgrades will be applied automatically
to the cache cluster during the maintenance window. A value of True
allows these upgrades to occur; False disables automatic upgrades.
security_group_ids
One or more VPC security groups associated with the cache cluster. Use
this parameter only when you are creating a cluster in a VPC.
cache_subnet_group_name
The name of the cache subnet group to be used for the cache cluster.
Use this parameter only when you are creating a cluster in a VPC.
engine_version
The version number of the cache engine to be used for this cluster.
notification_topic_arn
The Amazon Resource Name (ARN) of the Amazon Simple Notification
Service (SNS) topic to which notifications will be sent. The Amazon SNS
topic owner must be the same as the cache cluster owner.
preferred_maintenance_window
The weekly time range (in UTC) during which system maintenance can
occur. Example: sun:05:00-sun:09:00
wait
Boolean. Wait for confirmation from boto that the cluster is in the
available state.
region
Region to connect to.
key
Secret key to be used.
keyid
Access key to be used.
profile
A dict with region, key and keyid, or a pillar key (string)
that contains a dict with region, key and keyid.
