Lookup Plugins

Most of the AWS Lookup plugins contained here assume that you have a correctly configured .aws/credentials file. This provides the credentials for boto, the underlying AWS library used by Ansible.

AWS Regions

Allows you to look up the available AWS Regions and then filters out any that contain the string 'gov'

- shell: echo region is =={{ item }}==
  with_items: lookup('aws_regions').split(',')

Cloudformation

Allows you to look up Cloudformation stack output values.

The key should be structured like this:

{{ lookup('cloudformation', 'region/stackname/output/outputname') }}

and an actual example:

{{ lookup('cloudformation', 'eu-west-1/unixdaemon-natinstance/output/nat_group_id') }}

Elasticache Replica Group

Allows you to look up the endpoint address and port of a given Elasticache Replica Groups

The key should be structured like this:

{{ lookup('elasticache_replica_group', 'region/repl_group_name/query_value') }}

and some actual examples:

{{ lookup('elasticache_replica_group', 'ap-southeast-1/locarch2-elastiredis/endpoint_address') }}

{{ lookup('elasticache_replica_group', 'ap-southeast-1/locarch2-elastiredis/endpoint_port') }}

AWS Security Group ID

Allows you to look up the ID (something like sg-62f43457) of a remote security group.

"{{ lookup('aws_sg_id', 'eu-west-1/my-stack-name') }}"

I wrote this to avoid adding lots of outputs to certain templates.

AWS DefaultVPC ID

Allows you to look up the default VPC id for a given ec2 region.

- debug: msg="The default vpc is {{ lookup('default_vpc', 'ap-southeast-1') }}"

Currently doesn't handle ec2classics.
