  • python >= 2.6

  • boto

Parameters

Parameter Choices/Defaults Comments
access_logs
dictionary
An associative array of access logs configuration settings (see example)
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
connection_draining_timeout
integer
Wait a specified timeout allowing connections to drain before terminating an instance
cross_az_load_balancing
boolean
    Choices:
  • no ←
  • yes
Distribute load across all configured Availability Zones
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.
health_check
dictionary
An associative array of health check configuration settings (see example)
idle_timeout
integer
ELB connections from clients and to servers are timed out after this amount of time
instance_ids
list
List of instance ids to attach to this ELB
listeners
list
List of ports/protocols for this ELB to listen on (see example)
name
string / required
The name of the ELB
profile
string
Uses a boto profile. Only works with boto >= 2.24.0.
purge_instance_ids
boolean
    Choices:
  • no ←
  • yes
Purge existing instance ids on ELB that are not found in instance_ids
purge_listeners
boolean
    Choices:
  • no
  • yes ←
Purge existing listeners on ELB that are not found in listeners
purge_subnets
boolean
    Choices:

purge_zones
boolean
    Choices:
  • no ←
  • yes
Purge existing availability zones on ELB that are not found in zones
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
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
A list of security group names to apply to the elb
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
state
string / required
    Choices:
  • absent
  • present
Create or destroy the ELB
stickiness
dictionary
An associative array of stickiness policy settings. Policy will be applied to all listeners ( see example )
subnets
list
A list of VPC subnets to use when creating ELB. Zones should be empty if using this.
tags
dictionary
An associative array of tags. To delete all tags, supply an empty dict.
validate_certs
boolean
    Choices:
  • no
  • yes ←
When set to no, SSL certificates will not be validated for boto versions >= 2.6.0.
wait
boolean
    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
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.
