## Synopsis

- Manage an AWS Application Elastic Load Balancer. See https://aws.amazon.com/blogs/aws/new-aws-application-load-balancer/ 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
--- | --- | ---
access_logs_enabled boolean | Choices: no yes | Whether or not to enable access logs. When true, access_logs_s3_bucket must be set.
access_logs_s3_bucket - |  | The name of the S3 bucket for the access logs. Required if access logs in Amazon S3 are enabled. The bucket must exist in the same region as the load balancer and have a bucket policy that grants Elastic Load Balancing permission to write to the bucket.
access_logs_s3_prefix - |  | The prefix for the log location in the S3 bucket. If you don't specify a prefix, the access logs are stored in the root of the bucket. Cannot begin or end with a slash.
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
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.
deletion_protection boolean | Choices: no ← yes | Indicates whether deletion protection for the ELB is enabled.
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.
http2 boolean added in 2.6 | Choices: no ← yes | Indicates whether to enable HTTP2 routing.
idle_timeout - | Default: 60 | The number of seconds to wait before an idle connection is closed.
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 string |  | 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_rules boolean added in 2.7 | Choices: no yes ← | When set to no, keep the existing load balancer rules in place. Will modify and add, but will not delete.
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 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 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_groups - | Default: [] | A list of the names or IDs of the security groups to assign to the load balancer. Required if state=present.
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 - | Choices: present ← absent | Create or destroy the load balancer.
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.
tags - |  | A dictionary of one or more tags to assign to the load balancer.
validate_certs boolean | Choices: no yes ← | When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
wait boolean added in 2.6 | Choices: no ← yes | Wait for the load balancer to have a state of 'active' before completing. A status check is performed every 15 seconds until a successful state is reached. An error is returned after 40 failed checks.
wait_timeout - added in 2.6 |  | The time in seconds to use 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
