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.

name
string / required
The name of the ELB
profile
string
Uses a boto profile. Only works with boto >= 2.24.0.

aliases: aws_region, ec2_region
scheme
string
    Choices:
  • internal
  • internet-facing ←
The scheme to use when creating the ELB. For a private VPC-visible ELB use 'internal'. If you choose to update your scheme with a different value the ELB will be destroyed and recreated. To update scheme you must use the option wait.
security_group_ids
list
A list of security groups to apply to the elb
security_group_names
list

wait
boolean
added in 2.1
    Choices:
  • no ←
  • yes
When specified, Ansible will check the status of the load balancer to ensure it has been successfully removed from AWS.
wait_timeout
integer
added in 2.1
Default:
60
Used in conjunction with wait. Number of seconds to wait for the elb to be terminated. A maximum of 600 seconds (10 minutes) is allowed.
zones
list
List of availability zones to enable on this ELB

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: None of these examples set aws_access_key, aws_secret_key, or region.
# It is assumed that their matching environment variables are set.
