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.
names
-
List of ELB names to gather information about. Pass this option to gather information about a set of ELBs, otherwise, all ELBs are returned.

aliases: elb_ids, ec2_elbs
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_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
validate_certs
boolean
    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 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: These examples do not set authentication details, see the AWS Guide for details.
# Output format tries to match ec2_elb_lb module input parameters

# Gather information about all ELBs
- elb_classic_lb_info:
  register: elb_info

- debug:
    msg: "{{ item.dns_name }}"
  loop: "{{ elb_info.elbs }}"

# Gather information about a particular ELB
- elb_classic_lb_info:
    names: frontend-prod-elb
  register: elb_info

- debug:
    msg: "{{ elb_info.elbs.0.dns_name }}"

# Gather information about a set of ELBs
- elb_classic_lb_info:
    names:
    - frontend-prod-elb
    - backend-prod-elb
  register: elb_info

- debug:
    msg: "{{ item.dns_name }}"
