Synopsis

  • Returns list of matching Launch Configurations for a given name, along with other useful information
  • Results can be sorted and sliced
  • It depends on boto
  • Based on the work by Tom Bamford (https://github.com/tombamford)

Requirements

The below requirements are needed on the host that executes this module.

  • boto

  • python >= 2.6

Parameters

Parameter Choices/Defaults Comments
aws_access_key
string
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
string
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
debug_botocore_endpoint_logs
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.
limit
-
How many results to show.
Corresponds to Python slice notation like list[:limit].
name_regex
- / required
A Launch Configuration to match
It'll be compiled as regex
profile
string
Uses a boto profile. Only works with boto >= 2.24.0.
region
- / required
The AWS region to use.

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.

sort_order
-
    Choices:
  • ascending ←
  • descending
Order in which to sort results.
validate_certs

    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.

# Search for the Launch Configurations that start with "app"
- ec2_lc_find:
    name_regex: app.*
    sort_order: descending
    limit: 2
