ec2_eni - Create and optionally attach an Elastic Network Interface (ENI) to an instance
New in version 2.0.
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 >= 2.6
- boto
Parameters
Parameter | Choices/Defaults | Comments |
---|---|---|
attached (added in 2.2) | Default: yes | Specifies if network interface should be attached or detached from instance. If ommited, attachment status won't change |
aws_access_key | Default: None | 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 | Default: None | 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 |
delete_on_termination | 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. | |
description | Default: None | Optional description of the ENI. |
device_index | Default: 0 | The index of the device for the network interface attachment on the instance. |
ec2_url | Default: None | 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 | Default: None | The ID of the ENI (to modify); if null and state is present, a new eni will be created. |
force_detach | Default: no | Force detachment of the interface. This applies either when explicitly detaching the interface by setting instance_id to None or when deleting an interface with state=absent. |
instance_id | Default: None | 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'. |
private_ip_address | Default: None | Private IP address. |
profile (added in 1.6) | Default: None | Uses a boto profile. Only works with boto >= 2.24.0. |
purge_secondary_private_ip_addresses (added in 2.5) | Default: no | 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 an empty list to purge all secondary addresses. |
region | 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 | |
secondary_private_ip_address_count (added in 2.2) | 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 (added in 2.2) | 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 | Default: None | 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 (added in 1.6) | Default: None | 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 |
source_dest_check | 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. | |
state |
| Create or delete ENI |
subnet_id | ID of subnet in which to create the ENI. | |
validate_certs (added in 1.5) |
| When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0. |
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
orEC2_URL
,AWS_ACCESS_KEY_ID
orAWS_ACCESS_KEY
orEC2_ACCESS_KEY
,AWS_SECRET_ACCESS_KEY
orAWS_SECRET_KEY
orEC2_SECRET_KEY
,AWS_SECURITY_TOKEN
orEC2_SECURITY_TOKEN
,AWS_REGION
orEC2_REGION
- Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See http://boto.readthedocs.org/en/latest/boto_config_tut.html
-
AWS_REGION
orEC2_REGION
can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
Examples
# Note: These examples do not set authentication details, see the AWS Guide for details. # Create an ENI. As no security group is defined, ENI will be created in default security group - ec2_eni: private_ip_address: 172.31.0.20 subnet_id: subnet-xxxxxxxx state: present # Create an ENI and attach it to an instance - ec2_eni: instance_id: i-xxxxxxx device_index: 1 private_ip_address: 172.31.0.20 subnet_id: subnet-xxxxxxxx state: present # Create an ENI with two secondary addresses - ec2_eni: subnet_id: subnet-xxxxxxxx state: present secondary_private_ip_address_count: 2 # Assign a secondary IP address to an existing ENI # This will purge any existing IPs - ec2_eni: subnet_id: subnet-xxxxxxxx eni_id: eni-yyyyyyyy state: present secondary_private_ip_addresses: - 172.16.1.1 # Remove any secondary IP addresses from an existing ENI - ec2_eni: subnet_id: subnet-xxxxxxxx eni_id: eni-yyyyyyyy state: present secondary_private_ip_address_count: 0 # Destroy an ENI, detaching it from any instance if necessary - ec2_eni: eni_id: eni-xxxxxxx force_detach: yes state: absent # Update an ENI - ec2_eni: eni_id: eni-xxxxxxx description: "My new description" state: present # Update an ENI identifying it by private_ip_address and subnet_id - ec2_eni: subnet_id: subnet-xxxxxxx private_ip_address: 172.16.1.1 description: "My new description" # Detach an ENI from an instance - ec2_eni: eni_id: eni-xxxxxxx instance_id: None state: present ### Delete an interface on termination # First create the interface - ec2_eni: instance_id: i-xxxxxxx device_index: 1 private_ip_address: 172.31.0.20 subnet_id: subnet-xxxxxxxx state: present register: eni # Modify the interface to enable the delete_on_terminaton flag - ec2_eni: eni_id: "{{ eni.interface.id }}" delete_on_termination: true
