boto3 >= 1.16.0
botocore >= 1.19.0
Parameters
Parameter |
Comments |
|---|---|
If profile is set this parameter is ignored. Passing the aws_access_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01. |
|
The location of a CA Bundle to use when validating SSL certificates. Not used by boto 2 based modules. Note: The CA Bundle is read ‘module’ side and may need to be explicitly copied from the controller if not run locally. |
|
A dictionary to modify the botocore configuration. Parameters can be found at https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config. Only the ‘user_agent’ key is used for boto modules. See http://boto.cloudhackers.com/en/latest/boto_config_tut.html#boto for more boto configuration. |
|
If profile is set this parameter is ignored. Passing the aws_secret_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01. |
|
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. Choices:
|
|
Indicates whether the load balancer terminates connections at the end of the deregistration timeout. Using this option is only supported when attaching to a Network Load Balancer (NLB). Choices:
|
|
The amount time for Elastic Load Balancing to wait before changing the state of a deregistering target from draining to unused. The range is 0-3600 seconds. |
|
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. |
|
The approximate amount of time, in seconds, between health checks of an individual target. |
|
The ping path that is the destination on the targets for health checks. The path must be defined in order to set a health check. Requires the health_check_protocol parameter to be set. |
|
The port the load balancer uses when performing health checks on targets. Can be set to ‘traffic-port’ to match target port. When not defined will default to the port on which each target receives traffic from the load balancer. |
|
The protocol the load balancer uses when performing health checks on targets. Choices:
|
|
The amount of time, in seconds, during which no response from a target means a failed health check. |
|
The number of consecutive health checks successes required before considering an unhealthy target healthy. |
|
The type of load balancing algorithm to use. Changing the load balancing algorithm is only supported when used with Application Load Balancers (ALB). If not set AWS will default to Choices:
|
|
Whether or not to alter existing targets in the group to match what is passed with the module Choices:
|
|
The name of the target group. |
|
The port on which the targets receive traffic. This port is used unless you specify a port override when registering the target. Required when state is |
|
Indicates whether client IP preservation is enabled. The default is disabled if the target group type is preserve_client_ip_enabled is supported only by Network Load Balancers. Choices:
|
|
Using profile will override aws_access_key, aws_secret_key and security_token and support for passing them at the same time as profile has been deprecated. aws_access_key, aws_secret_key and security_token will be made mutually exclusive with profile after 2022-06-01. |
|
The protocol to use for routing traffic to the targets. Required when state is Choices:
|
|
Indicates whether Proxy Protocol version 2 is enabled. The value is proxy_protocol_v2_enabled is supported only by Network Load Balancers. Choices:
|
|
If yes, existing tags will be purged from the resource to match exactly what is defined by tags parameter. If the tag parameter is not set then tags will not be modified. Choices:
|
|
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 |
|
If profile is set this parameter is ignored. Passing the security_token and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01. Aliases aws_session_token and session_token have been added in version 3.2.0. |
|
Create or destroy the target group. Choices:
|
|
The time period, in seconds, during which requests from a client should be routed to the same target. After this time period expires, the application-generated cookie is considered stale. The range is 1 second to 1 week (604800 seconds). |
|
The name of the application cookie. Required if stickiness_type=app_cookie. |
|
Indicates whether sticky sessions are enabled. Choices:
|
|
The time period, in seconds, during which requests from a client should be routed to the same target. After this time period expires, the load balancer-generated cookie is considered stale. The range is 1 second to 1 week (604800 seconds). |
|
The type of sticky sessions. Valid values are If not set AWS will default to |
|
The HTTP codes to use when checking for a successful response from a target. Accepts multiple values (for example, “200,202”) or a range of values (for example, “200-299”). Requires the health_check_protocol parameter to be set. |
|
A dictionary of one or more tags to assign to the target group. |
|
The type of target that you must specify when registering targets with this target group. The possible values are The default behavior is Choices:
|
|
A list of targets to assign to the target group. This parameter defaults to an empty list. Unless you set the ‘modify_targets’ parameter then all existing targets will be removed from the group. The list should be an Id and a Port parameter. See the Examples for detail. |
|
The number of consecutive health check failures required before considering a target unhealthy. |
|
When set to “no”, SSL certificates will not be validated for communication with the AWS APIs. Choices:
|
|
The identifier of the virtual private cloud (VPC). Required when state is |
|
Whether or not to wait for the target group. Choices:
|
|
The time to wait for the target group. Default: |
Notes
Note
Once a target group has been created, only its health check can then be modified using subsequent calls
If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence
AWS_URLorEC2_URL,AWS_PROFILEorAWS_DEFAULT_PROFILE,AWS_ACCESS_KEY_IDorAWS_ACCESS_KEYorEC2_ACCESS_KEY,AWS_SECRET_ACCESS_KEYorAWS_SECRET_KEYorEC2_SECRET_KEY,AWS_SECURITY_TOKENorEC2_SECURITY_TOKEN,AWS_REGIONorEC2_REGION,AWS_CA_BUNDLEWhen no credentials are explicitly provided the AWS SDK (boto3) that Ansible uses will fall back to its configuration files (typically
~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.Modules based on the original AWS SDK (boto) may read their default configuration from different files. See https://boto.readthedocs.io/en/latest/boto_config_tut.html for more information.
AWS_REGIONorEC2_REGIONcan be typically be used to specify the AWS region, when required, but this can also be defined in the configuration files.
