amazon.aws.ec2_eni module – Create and optionally attach an Elastic Network Interface (ENI) to an instance

Note

This module is part of the amazon.aws collection (version 2.3.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install amazon.aws.

To use it in a playbook, specify: amazon.aws.ec2_eni.

New in version 1.0.0: of amazon.aws

Synopsis

• Create and optionally attach an Elastic Network Interface (ENI) to an instance. If an ENI ID or private_ip is provided, the existing ENI (if any) will be modified. The ‘attached’ parameter controls the attachment status of the network interface.

Requirements

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

• python >= 3.6

• boto3 >= 1.15.0

• botocore >= 1.18.0

Parameters

Parameter	Comments
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: no ← (default) yes
attached boolean	Specifies if network interface should be attached or detached from instance. If omitted, attachment status won’t change Choices: no yes
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.
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
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: no yes
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
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.
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: no ← (default) yes
instance_id string	Instance ID that you wish to attach ENI to. Since version 2.2, use the attached parameter to attach or detach an ENI. Prior to 2.2, to detach an ENI from an instance, use None.
name string	Name for the ENI. This will create a tag called “Name” with 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	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_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: no ← (default) yes
purge_tags boolean added in 1.3.0 of amazon.aws	Indicates whether to remove tags not specified in tags or name. This means you have to specify all the desired tags on each task affecting a network interface. If tags is omitted or None this option is disregarded. Choices: no yes ← (default)
region aliases: aws_region, ec2_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
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
security_groups list / elements=string	List of security groups associated with the interface. Only used when state=present. Since version 2.2, you can specify security groups by ID or by name or a combination of both. Prior to 2.2, you can specify only by ID.
security_token aliases: aws_security_token, access_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. 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.
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: no yes
state string	Create or delete ENI. Choices: present ← (default) absent
subnet_id string	ID of subnet in which to create the ENI.
tags dictionary added in 1.3.0 of amazon.aws	A hash/dictionary of tags to add to the new ENI or to add/remove from an existing one. Please note that the name field sets the “Name” tag. To clear all tags, set this option to an empty dictionary to use in conjunction with purge_tags. If you provide name, that tag will not be removed. To prevent removing any tags set purge_tags to false.
validate_certs boolean	When set to “no”, SSL certificates will not be validated for communication with the AWS APIs. Choices: no yes ← (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.

• 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.
