Synopsis
Manage an AWS Elastic Load Balancer target group. See https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-target-groups.html or https://docs.aws.amazon.com/elasticloadbalancing/latest/network/load-balancer-target-groups.html for details.
Requirements
The below requirements are needed on the host that executes this module.
boto
boto3
python >= 2.6
Parameters
Parameter |
Comments |
|---|---|
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. 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. Only used for boto3 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. |
|
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. 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:
|
|
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. |
|
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 if state is |
|
Uses a boto profile. Only works with boto >= 2.24.0. 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:
|
|
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 |
|
AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. 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. |
|
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 boto versions >= 2.6.0. 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: 200 |
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_BUNDLEAnsible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html
AWS_REGIONorEC2_REGIONcan be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
