## Synopsis

- Can create or delete AWS Autoscaling Configurations
- Works with the ec2_asg module to manage Autoscaling Groups

## Requirements

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

- boto
- boto3 >= 1.4.4
- python >= 2.6

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
assign_public_ip - |  | Used for Auto Scaling groups that launch instances into an Amazon Virtual Private Cloud. Specifies whether to assign a public IP address to each instance launched in a Amazon VPC.
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
classic_link_vpc_id - |  | Id of ClassicLink enabled VPC
classic_link_vpc_security_groups - |  | A list of security group IDs with which to associate the ClassicLink VPC instances.
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.
ebs_optimized - | Default: "no" | Specifies whether the instance is optimized for EBS I/O (true) or not (false).
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.
image_id - |  | The AMI unique identifier to be used for the group
instance_id - added in 2.4 |  | The Id of a running instance to use as a basis for a launch configuration. Can be used in place of image_id and instance_type.
instance_monitoring boolean | Choices: no ← yes | Specifies whether instances are launched with detailed monitoring.
instance_profile_name - |  | The name or the Amazon Resource Name (ARN) of the instance profile associated with the IAM role for the instances.
instance_type - / required |  | Instance type to use for the instance
kernel_id - |  | Kernel id for the EC2 instance
key_name - |  | The SSH key name to be used for access to managed instances
name - / required |  | Unique name for configuration
placement_tenancy - added in 2.4 | Default: "default" | Determines whether the instance runs on single-tenant hardware or not.
profile string |  | Uses a boto profile. Only works with boto >= 2.24.0.
ramdisk_id - |  | A RAM disk id for the instances.
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_groups - |  | A list of security groups to apply to the instances. Since version 2.4 you can specify either security group names or IDs or a mix. Previous to 2.4, for VPC instances, specify security group IDs and for EC2-Classic, specify either security group names or IDs.
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. aliases: access_token
spot_price - |  | The spot price you are bidding. Only applies for an autoscaling group with spot instances.
state - | Choices: present ← absent | Register or deregister the instance
user_data - |  | Opaque blob of data which is made available to the ec2 instance. Mutually exclusive with user_data_path.
user_data_path - |  | Path to the file that contains userdata for the ec2 instances. Mutually exclusive with user_data.
validate_certs boolean | Choices: no yes ← | When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
volumes - |  | A list of volume dicts, each containing device name and optionally ephemeral id or snapshot id. Size and type (and number of iops for io device type) must be specified for a new volume or a root volume, and may be passed for a snapshot volume. For any volume, a volume size less than 1 will be interpreted as a request not to create the volume.
vpc_id - added in 2.4 |  | VPC ID, used when resolving security group names to IDs.

## Notes

Note

- Amazon ASG Autoscaling Launch Configurations are immutable once created, so modifying the configuration after it is changed will not modify the launch configuration on AWS. You must create a new config and assign it to the ASG instead.
- encrypted volumes are supported on versions >= 2.4
- 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
