Parameters

Parameter	Comments
access_key aliases: aws_access_key_id, aws_access_key, ec2_access_key string	AWS access key ID. See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys. The AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variables may also be used in decreasing order of preference. The aws_access_key and profile options are mutually exclusive. The aws_access_key_id alias was added in release 5.1.0 for consistency with the AWS botocore SDK. The ec2_access_key alias has been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_ACCESS_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.
allow_reassignment boolean	Indicates whether to allow an IP address that is already assigned to another network interface or instance to be reassigned to the specified network interface. Choices: false ← (default) true
attached boolean	Specifies if network interface should be attached or detached from instance. If omitted, attachment status won’t change Choices: false true
aws_ca_bundle path	The location of a CA Bundle to use when validating SSL certificates. The AWS_CA_BUNDLE environment variable may also be used.
aws_config dictionary	A dictionary to modify the botocore configuration. Parameters can be found in the AWS documentation https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config.
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: false ← (default) true
delete_on_termination boolean	Delete the interface when the instance it is attached to is terminated. You can only specify this flag when the interface is being modified, not on creation. Choices: false true
description string	Optional description of the ENI.
device_index integer	The index of the device for the network interface attachment on the instance. Default: 0
endpoint_url aliases: ec2_url, aws_endpoint_url, s3_url string	URL to connect to instead of the default AWS endpoints. While this can be used to connection to other AWS-compatible services the amazon.aws and community.aws collections are only tested against AWS. The AWS_URL or EC2_URL environment variables may also be used, in decreasing order of preference. The ec2_url and s3_url aliases have been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_URL environment variable has been deprecated and will be removed in a release after 2024-12-01.
eni_id string	The ID of the ENI (to modify). If eni_id=None and state=present, a new ENI will be created.
force_detach boolean	Force detachment of the interface. This applies either when explicitly detaching the interface by setting instance_id=None or when deleting an interface with state=absent. Choices: false ← (default) true
instance_id string	Instance ID that you wish to attach ENI to.
name string	Name for the ENI. This will create a tag with the key Name and the value assigned here. This can be used in conjunction with subnet_id as another means of identifiying a network interface. AWS does not enforce unique Name tags, so duplicate names are possible if you configure it that way. If that is the case, you will need to provide other identifying information such as private_ip_address or eni_id.
private_ip_address string	Private IP address.
profile aliases: aws_profile string	A named AWS profile to use for authentication. See the AWS documentation for more information about named profiles https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html. The AWS_PROFILE environment variable may also be used. The profile option is mutually exclusive with the aws_access_key, aws_secret_key and security_token options.
purge_secondary_private_ip_addresses boolean	To be used with secondary_private_ip_addresses to determine whether or not to remove any secondary IP addresses other than those specified. Set secondary_private_ip_addresses=[] to purge all secondary addresses. Choices: false ← (default) true
purge_tags boolean	If purge_tags=true and tags is set, 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, even if purge_tags=True. Tag keys beginning with aws: are reserved by Amazon and can not be modified. As such they will be ignored for the purposes of the purge_tags parameter. See the Amazon documentation for more information https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html#tag-conventions. Choices: false true ← (default)
region aliases: aws_region, ec2_region string	The AWS region to use. For global services such as IAM, Route53 and CloudFront, region is ignored. The AWS_REGION or EC2_REGION environment variables may also be used. See the Amazon AWS documentation for more information http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region. The ec2_region alias has been deprecated and will be removed in a release after 2024-12-01 Support for the EC2_REGION environment variable has been deprecated and will be removed in a release after 2024-12-01.
secondary_private_ip_address_count integer	The number of secondary IP addresses to assign to the network interface. This option is mutually exclusive of secondary_private_ip_addresses.
secondary_private_ip_addresses list / elements=string	A list of IP addresses to assign as secondary IP addresses to the network interface. This option is mutually exclusive of secondary_private_ip_address_count.
secret_key aliases: aws_secret_access_key, aws_secret_key, ec2_secret_key string	AWS secret access key. See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys. The AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variables may also be used in decreasing order of preference. The secret_key and profile options are mutually exclusive. The aws_secret_access_key alias was added in release 5.1.0 for consistency with the AWS botocore SDK. The ec2_secret_key alias has been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_SECRET_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.
security_groups list / elements=string	List of security groups associated with the interface. Ignored when state=absent. Default: []
session_token aliases: aws_session_token, security_token, aws_security_token, access_token string	AWS STS session token for use with temporary credentials. See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys. The AWS_SESSION_TOKEN, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variables may also be used in decreasing order of preference. The security_token and profile options are mutually exclusive. Aliases aws_session_token and session_token were added in release 3.2.0, with the parameter being renamed from security_token to session_token in release 6.0.0. The security_token, aws_security_token, and access_token aliases have been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_SECRET_KEY and AWS_SECURITY_TOKEN environment variables has been deprecated and will be removed in a release after 2024-12-01.
source_dest_check boolean	By default, interfaces perform source/destination checks. NAT instances however need this check to be disabled. You can only specify this flag when the interface is being modified, not on creation. Choices: false true
state string	Create or delete ENI. Choices: "present" ← (default) "absent"
subnet_id string	ID of subnet in which to create the ENI.
tags aliases: resource_tags dictionary	A dictionary representing the tags to be applied to the resource. If the tags parameter is not set then tags will not be modified.
validate_certs boolean	When set to false, SSL certificates will not be validated for communication with the AWS APIs. Setting validate_certs=false is strongly discouraged, as an alternative, consider setting aws_ca_bundle instead. Choices: false true ← (default)

Notes

Note

• This module identifies and ENI based on either the eni_id, a combination of private_ip_address and subnet_id, or a combination of instance_id and device_id. Any of these options will let you specify a particular ENI.

• Support for tags and purge_tags was added in release 1.3.0.

• Caution: For modules, environment variables and configuration files are read from the Ansible ‘host’ context and not the ‘controller’ context. As such, files may need to be explicitly copied to the ‘host’. For lookup and connection plugins, environment variables and configuration files are read from the Ansible ‘controller’ context and not the ‘host’ context.

• The AWS SDK (boto3) that Ansible uses may also read defaults for credentials and other settings, such as the region, from its configuration files in the Ansible ‘host’ context (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.
