Synopsis ¶

Manage an AWS Network Elastic Load Balancer. See https://aws.amazon.com/blogs/aws/new-network-load-balancer-effortless-scaling-to-millions-of-requests-per-second/ 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
cross_zone_load_balancing boolean	Choices: no ← yes	Indicates whether cross-zone load balancing is enabled.
deletion_protection boolean	Choices: no ← yes	Indicates whether deletion protection for the ELB is enabled.
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.
listeners -		A list of dicts containing listeners to attach to the ELB. See examples for detail of the dict required. Note that listener keys are CamelCased.
name - / required		The name of the load balancer. This name must be unique within your AWS account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen.
profile - added in 1.6		Uses a boto profile. Only works with boto >= 2.24.0.
purge_listeners boolean	Choices: no yes ←	If yes, existing listeners will be purged from the ELB to match exactly what is defined by listeners parameter. If the listeners parameter is not set then listeners will not be modified
purge_tags boolean	Choices: no yes ←	If yes, existing tags will be purged from the resource to match exactly what is defined by tags parameter. If the tags 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
scheme -	Choices: internet-facing ← internal	Internet-facing or internal load balancer. An ELB scheme can not be modified after creation.
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 load balancer.
subnet_mappings -		A list of dicts containing the IDs of the subnets to attach to the load balancer. You can also specify the allocation ID of an Elastic IP to attach to the load balancer. You can specify one Elastic IP address per subnet. This parameter is mutually exclusive with subnets
subnets -		A list of the IDs of the subnets to attach to the load balancer. You can specify only one subnet per Availability Zone. You must specify subnets from at least two Availability Zones. Required if state=present. This parameter is mutually exclusive with subnet_mappings
tags -		A dictionary of one or more tags to assign to the load balancer.
validate_certs boolean added in 1.5	Choices: no yes ←	When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
wait boolean	Choices: no yes	Whether or not to wait for the network load balancer to reach the desired state.
wait_timeout -		The duration in seconds to wait, used in conjunction with wait.

Notes ¶

Note

Listeners are matched based on port. If a listener’s port is changed then a new listener will be created.
Listener rules are matched based on priority. If a rule’s priority is changed then a new rule will be created.
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
