salt.states.boto_elasticache¶

Manage Elasticache¶

New in version 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.

If IAM roles are not used you need to specify them either in a pillar file or in the minion's config file:

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:

myprofile:
  keyid: GKTADJGHEIQSXMKKRBJ08H
  key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
    region: us-east-1

Ensure myelasticache exists:
  boto_elasticache.present:
    - name: myelasticache
    - engine: redis
    - cache_node_type: cache.t1.micro
    - num_cache_nodes: 1
    - notification_topic_arn: arn:aws:sns:us-east-1:879879:my-sns-topic
    - region: us-east-1
    - keyid: GKTADJGHEIQSXMKKRBJ08H
    - key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs

# Using a profile from pillars
Ensure myelasticache exists:
  boto_elasticache.present:
    - name: myelasticache
    - engine: redis
    - cache_node_type: cache.t1.micro
    - num_cache_nodes: 1
    - notification_topic_arn: arn:aws:sns:us-east-1:879879:my-sns-topic
    - region: us-east-1
    - profile: myprofile

# Passing in a profile
Ensure myelasticache exists:
  boto_elasticache.present:
    - name: myelasticache
    - engine: redis
    - cache_node_type: cache.t1.micro
    - num_cache_nodes: 1
    - notification_topic_arn: arn:aws:sns:us-east-1:879879:my-sns-topic
    - region: us-east-1
    - profile:
        keyid: GKTADJGHEIQSXMKKRBJ08H
        key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs

salt.states.boto_elasticache.absent(name, wait=True, region=None, key=None, keyid=None, profile=None)¶

Ensure the named elasticache cluster is deleted.

name: Name of the cache cluster.
wait: Boolean. Wait for confirmation from boto that the cluster is in the deleting 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.

salt.states.boto_elasticache.present(name, engine, cache_node_type, num_cache_nodes=1, preferred_availability_zone=None, port=None, cache_parameter_group_name=None, cache_security_group_names=None, replication_group_id=None, auto_minor_version_upgrade=True, security_group_ids=None, cache_subnet_group_name=None, engine_version=None, notification_topic_arn=None, preferred_maintenance_window=None, wait=True, region=None, key=None, keyid=None, profile=None)¶

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: http://boto.readthedocs.org/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 creating 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.
