Synopsis ¶

Manage an AWS Elastic Load Balancer target group. See http://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-target-groups.html or http://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	Choices/Defaults	Comments
aws_access_key		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		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
deregistration_delay_timeout		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.
ec2_url		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_interval		The approximate amount of time, in seconds, between health checks of an individual target.
health_check_path		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.
health_check_port	Default: The port on which each target receives traffic from the load balancer.	The port the load balancer uses when performing health checks on targets. Can be set to 'traffic-port' to match target port.
health_check_protocol	Choices: http https tcp	The protocol the load balancer uses when performing health checks on targets.
health_check_timeout		The amount of time, in seconds, during which no response from a target means a failed health check.
healthy_threshold_count		The number of consecutive health checks successes required before considering an unhealthy target healthy.
modify_targets	Default: yes	Whether or not to alter existing targets in the group to match what is passed with the module
name required		The name of the target group.
port		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 `present`.
profile (added in 1.6)		Uses a boto profile. Only works with boto >= 2.24.0.
protocol	Choices: http https tcp	The protocol to use for routing traffic to the targets. Required when state is `present`.
purge_tags bool	Choices: no yes ←	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.
region		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 aliases: aws_region, ec2_region
security_token (added in 1.6)		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 required	Choices: present absent	Create or destroy the target group.
stickiness_enabled bool	Choices: no yes	Indicates whether sticky sessions are enabled.
stickiness_lb_cookie_duration		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).
stickiness_type	Default: lb_cookie	The type of sticky sessions. The possible value is lb_cookie.
successful_response_codes		The HTTP codes to use when checking for a successful response from a target. You can specify multiple values (for example, "200,202") or a range of values (for example, "200-299").
tags		A dictionary of one or more tags to assign to the target group.
target_type (added in 2.5)	Choices: instance ← ip	The type of target that you must specify when registering targets with this target group. The possible values are `instance` (targets are specified by instance ID) or `ip` (targets are specified by IP address). Note that you can't specify targets for a target group using both instance IDs and IP addresses. If the target type is ip, specify IP addresses from the subnets of the virtual private cloud (VPC) for the target group, the RFC 1918 range (10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16), and the RFC 6598 range (100.64.0.0/10). You can't specify publicly routable IP addresses.
targets		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.
unhealthy_threshold_count		The number of consecutive health check failures required before considering a target unhealthy.
validate_certs bool (added in 1.5)	Choices: no yes ←	When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
vpc_id		The identifier of the virtual private cloud (VPC). Required when state is `present`.
wait bool (added in 2.4)	Choices: no ← yes	Whether or not to wait for the target group.
wait_timeout (added in 2.4)	Default: 200	The time to wait for the target group.

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_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
