Synopsis

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 3.6

  • boto3 >= 1.16.0

  • botocore >= 1.19.0

Parameters

Parameter

Comments

aws_access_key

aliases: ec2_access_key, 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.

aws_ca_bundle

path

The location of a CA Bundle to use when validating SSL certificates.

Not used by boto 2 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.

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

aliases: ec2_secret_key, 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.

cross_zone_load_balancing

boolean

Indicates whether cross-zone load balancing is enabled.

Defaults to false.

Choices:

  • no

  • yes

debug_botocore_endpoint_logs

boolean

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:

  • no ← (default)

  • yes

deletion_protection

boolean

Indicates whether deletion protection for the ELB is enabled.

Defaults to false.

Choices:

  • no

  • yes

ec2_url

aliases: aws_endpoint_url, endpoint_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.

ip_address_type

string

Sets the type of IP addresses used by the subnets of the specified Application Load Balancer.

Choices:

  • ipv4

  • dualstack

listeners

list / elements=dictionary

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.

Certificates

list / elements=dictionary

The SSL server certificate.

CertificateArn

string

The Amazon Resource Name (ARN) of the certificate.

DefaultActions

list / elements=dictionary / required

The default actions for the listener.

TargetGroupArn

The Amazon Resource Name (ARN) of the target group.

Type

string

The type of action.

Port

integer / required

The port on which the load balancer is listening.

Protocol

string / required

The protocol for connections from clients to the load balancer.

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

aliases: aws_profile

string

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.

purge_listeners

boolean

If purge_listeners=true, 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.

Choices:

  • no

  • yes ← (default)

purge_tags

boolean

If purge_tags=true, 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.

Choices:

string

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.

state

string

Create or destroy the load balancer.

The current default is absent. However, this behavior is inconsistent with other modules and as such the default will change to present in a release after 2022-06-01. To maintain the existing behavior explicitly set state=absent.

Choices:

  • present

  • absent

subnet_mappings

list / elements=dictionary

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 or the internal IP address for an internal load balancer. You can specify one Elastic IP address or internal address per subnet.

This parameter is mutually exclusive with subnets.

subnets

list / elements=string

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 when state=present.

This parameter is mutually exclusive with subnet_mappings.

tags

dictionary

When set to “no”, SSL certificates will not be validated for communication with the AWS APIs.

Choices:

  • no

wait

boolean

Whether or not to wait for the network load balancer to reach the desired state.

Choices:

  • no

  • yes

wait_timeout

integer

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_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

  • When no credentials are explicitly provided the AWS SDK (boto3) that Ansible uses will fall back to its configuration files (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.

  • Modules based on the original AWS SDK (boto) may read their default configuration from different files. See https://boto.readthedocs.io/en/latest/boto_config_tut.html for more information.

  • AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be defined in the configuration files.
