amazon.aws.ec2_vpc_dhcp_option – Manages DHCP Options, and can ensure the DHCP options for the given VPC match what’s requested

Note

This plugin is part of the amazon.aws collection (version 1.3.0).

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

To use it in a playbook, specify: amazon.aws.ec2_vpc_dhcp_option.


New in version 1.0.0: of amazon.aws


Synopsis

  • This module removes, or creates DHCP option sets, and can associate them to a VPC. Optionally, a new DHCP Options set can be created that converges a VPC’s existing DHCP option set with values provided. When dhcp_options_id is provided, the module will 1. remove (with state=’absent’) 2. ensure tags are applied (if state=’present’ and tags are provided 3. attach it to a VPC (if state=’present’ and a vpc_id is provided. If any of the optional values are missing, they will either be treated as a no-op (i.e., inherit what already exists for the VPC) To remove existing options while inheriting, supply an empty value (e.g. set ntp_servers to [] if you want to remove them from the VPC’s options) Most of the options should be self-explanatory.

Requirements

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

  • boto
  • python >= 2.6

Parameters

Parameter Choices/Defaults Comments

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.

delete_old

boolean

  • no

  • yes ←

Whether to delete the old VPC DHCP option set when associating a new one. This is primarily useful for debugging/development purposes when you want to quickly roll back to the old option set. Note that this setting will be ignored, and the old DHCP option set will be preserved, if it is in use by any other VPC. (Otherwise, AWS will return an error.)

dhcp_options_id

string

The resource_id of an existing DHCP options set. If this is specified, then it will override other settings, except tags (which will be updated to match)

dns_servers

list / elements=string

A list of hosts to set the DNS servers for the VPC to. (Should be a list of IP addresses rather than host names.)

domain_name

string

The domain name to set in the DHCP option sets

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

inherit_existing

boolean

  • no ←

  • yes

For any DHCP options not specified in these parameters, whether to inherit them from the options set already applied to vpc_id, or to reset them to be empty.

netbios_name_servers

list / elements=string

List of hosts to advertise as NetBIOS servers.

netbios_node_type

integer

NetBIOS node type to advertise in the DHCP options. The AWS recommendation is to use 2 (when using netbios name services) https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_DHCP_Options.html

ntp_servers

list / elements=string

List of hosts to advertise as NTP servers for the VPC.

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

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


aliases: aws_region, ec2_region

security_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.


aliases: aws_security_token, access_token

state

string

  • absent

  • present ←

create/assign or remove the DHCP options. If state is set to absent, then a DHCP options set matched either by id, or tags and options will be removed if possible.

tags

dictionary

Tags to be applied to a VPC options set if a new one is created, or if the resource_id is provided. (options must match)


aliases: resource_tags

validate_certs

boolean

  • no

  • yes ←

When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

vpc_id

string

VPC ID to associate with the requested DHCP option set. If no vpc id is provided, and no matching option set is found then a new DHCP option set is created.



Notes

Note

  • 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
