ec2_asg_facts - Gather facts about ec2 Auto Scaling Groups (ASGs) in AWS

New in version 2.2.

Synopsis

Gather facts about ec2 Auto Scaling Groups (ASGs) in AWS

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		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		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
ec2_url		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.
name		The prefix or name of the auto scaling group(s) you are searching for. Note: This is a regular expression match with implicit '^' (beginning of string). Append '$' for a complete name match.
profile (added in 1.6)		Uses a boto profile. Only works with boto >= 2.24.0.
region		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_token (added in 1.6)		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
tags		A dictionary/hash of tags in the format { tag1_name: 'tag1_value', tag2_name: 'tag2_value' } to match against the auto scaling group(s) you are searching for.
validate_certs bool (added in 1.5)	Choices: no yes ←	When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

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 http://boto.readthedocs.org/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: These examples do not set authentication details, see the AWS Guide for details.

# Find all groups
- ec2_asg_facts:
  register: asgs

# Find a group with matching name/prefix
- ec2_asg_facts:
    name: public-webserver-asg
  register: asgs

# Find a group with matching tags
- ec2_asg_facts:
    tags:
      project: webapp
      env: production
  register: asgs

# Find a group with matching name/prefix and tags
- ec2_asg_facts:
    name: myproject
    tags:
      env: production
  register: asgs

# Fail if no groups are found
- ec2_asg_facts:
    name: public-webserver-asg
  register: asgs
  failed_when: "{{ asgs.results | length == 0 }}"

# Fail if more than 1 group is found
- ec2_asg_facts:
    name: public-webserver-asg
  register: asgs
  failed_when: "{{ asgs.results | length > 1 }}"
