Synopsis

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

  • no
  • yes

Whether or not to enable access logs.

When set, access_logs_s3_bucket must also be set.

access_logs_s3_bucket

string

The name of the S3 bucket for the access logs.

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.

Required if access logs in Amazon S3 are enabled.

When set, access_logs_enabled must also be set.

access_logs_s3_prefix

string

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.

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.


aliases: ec2_access_key, access_key

aws_ca_bundle

path

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.

aws_config

dictionary

A dictionary to modify the botocore configuration.

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

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.

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.


aliases: ec2_secret_key, secret_key

debug_botocore_endpoint_logs

boolean

  • 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

  • no
  • yes

Indicates whether deletion protection for the ELB is enabled.

Defaults to false.

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.


aliases: aws_endpoint_url, endpoint_url

http2

boolean

  • no
  • yes

Indicates whether to enable HTTP2 routing.

Defaults to false.

idle_timeout

integer

The number of seconds to wait before an idle connection is closed.

Conditions which must be met for the actions to be applied.

Priority

integer

The rule priority.

SslPolicy

string

The security policy that defines which ciphers and protocols are supported.

name

string / 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.

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.


aliases: aws_profile

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_PROFILE or AWS_DEFAULT_PROFILE, 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, AWS_CA_BUNDLE
  • 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
