## Synopsis

- Create, modify, and delete EC2 Launch Templates, which can be used to create individual instances or with Autoscaling Groups.

- The ec2_instance and ec2_asg modules can, instead of specifying all parameters on those tasks, be passed a Launch Template which contains settings like instance size, disk type, subnet, and more.

## Requirements

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

- boto

- boto3 >= 1.6.0

- botocore

- 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. aliases: ec2_access_key, access_key
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. aliases: ec2_secret_key, secret_key

block_device_mappings
-

The block device mapping. Supplying both a snapshot ID and an encryption value as arguments for block-device mapping results in an error. This is because only blank volumes can be encrypted on start, and these are not created from a snapshot. If a snapshot is the basis for the volume, it contains data by definition and its encryption status cannot be changed using this action.

| device_name - |  | The device name (for example, /dev/sdh or xvdh).
| ebs - |  | Parameters used to automatically set up EBS volumes when the instance is launched.

delete_on_termination
boolean

Choices:
- no
- yes

Indicates whether the EBS volume is deleted on instance termination.

|  | encrypted - |  | Indicates whether the EBS volume is encrypted. Encrypted volumes can only be attached to instances that support Amazon EBS encryption. If you are creating a volume from a snapshot, you can't specify an encryption value.

iops
-

The number of I/O operations per second (IOPS) that the volume supports. For io1, this represents the number of IOPS that are provisioned for the volume. For gp2, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting. For more information about General Purpose SSD baseline performance, I/O credits, and bursting, see Amazon EBS Volume Types in the Amazon Elastic Compute Cloud User Guide.
Condition: This parameter is required for requests to create io1 volumes; it is not used in requests to create gp2, st1, sc1, or standard volumes.

|  | kms_key_id - |  | The ARN of the AWS Key Management Service (AWS KMS) CMK used for encryption.
|  | snapshot_id - |  | The ID of the snapshot to create the volume from
|  | volume_size - |  | The size of the volume, in GiB. Default: If you're creating the volume from a snapshot and don't specify a volume size, the default is the snapshot size.
|  | volume_type - |  | The volume type
| no_device - |  | Suppresses the specified device included in the block device mapping of the AMI.
| virtual_name - |  | The virtual device name (ephemeralN). Instance store volumes are numbered starting from 0. An instance type with 2 available instance store volumes can specify mappings for ephemeral0 and ephemeral1. The number of available instance store volumes depends on the instance type. After you connect to the instance, you must mount the volume.
cpu_options - |  | Choose CPU settings for the EC2 instances that will be created with this template. For more information, see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-optimize-cpu.html
| core_count - |  | The number of CPU cores for the instance.
| threads_per_core - |  | The number of threads per CPU core. To disable Intel Hyper-Threading Technology for the instance, specify a value of 1. Otherwise, specify the default value of 2.
credit_specification - |  | The credit option for CPU usage of the instance. Valid for T2 or T3 instances only.

cpu_credits
-

Choices:
- standard
- unlimited

The credit option for CPU usage of a T2 or T3 instance. Valid values are standard and unlimited.

debug_botocore_endpoint_logs
boolean
added in 2.8

Choices:
- 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.

default_version - | Default: "latest" | Which version should be the default when users spin up new instances based on this template? By default, the latest version will be made the default.

disable_api_termination
boolean

Choices:
- no
- yes

This helps protect instances from accidental termination. If set to true, you can't terminate the instance using the Amazon EC2 console, CLI, or API. To change this attribute to false after launch, use ModifyInstanceAttribute.

ebs_optimized
boolean

Choices:
- no
- yes

Indicates whether the instance is optimized for Amazon EBS I/O. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal Amazon EBS I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using an EBS-optimized instance.

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.
elastic_gpu_specifications - |  | Settings for Elastic GPU attachments. See https://aws.amazon.com/ec2/elastic-gpus/ for details.
| type - |  | The type of Elastic GPU to attach
iam_instance_profile - |  | The name or ARN of an IAM instance profile. Requires permissions to describe existing instance roles to confirm ARN is properly formed.
image_id - |  | The AMI ID to use for new instances launched with this template. This value is region-dependent since AMIs are not global resources.

instance_initiated_shutdown_behavior
-

Choices:
- stop
- terminate

Indicates whether an instance stops or terminates when you initiate shutdown from the instance using the operating system shutdown command.

instance_market_options dictionary |  | Options for alternative instance markets, currently only the spot market is supported.
| market_type - |  | The market type. This should always be 'spot'.
| spot_options - |  | Spot-market specific settings
|  | block_duration_minutes - |  | The required duration for the Spot Instances (also known as Spot blocks), in minutes. This value must be a multiple of 60 (60, 120, 180, 240, 300, or 360).

instance_interruption_behavior
-

Choices:
- hibernate
- stop
- terminate

## 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_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`

- 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
