module: ec2_lc
short_description: Create or delete AWS Autoscaling Launch Configurations
description:
- Can create or delete AWS Autoscaling Configurations
- Works with the ec2_asg module to manage Autoscaling Groups
notes:
- "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."
version_added: "1.6"
author: "Gareth Rushgrove (@garethr)"
options:
state:
description:
- register or deregister the instance
required: true
choices: ['present', 'absent']
name:
description:
- Unique name for configuration
required: true
instance_type:
description:

required: false
key_name:
description:
- The SSH key name to be used for access to managed instances
required: false
security_groups:
description:
- A list of security groups to apply to the instances. For VPC instances, specify security group IDs. For EC2-Classic, specify either security group names or IDs.
required: false
volumes:
description:
- 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.
required: false
user_data:
description:
- opaque blob of data which is made available to the ec2 instance
required: false
kernel_id:
description:
- Kernel id for the EC2 instance
required: false
spot_price:
description:
- The spot price you are bidding. Only applies for an autoscaling group with spot instances.
required: false
instance_monitoring:
description:
- whether instances in group are launched with detailed monitoring.
default: false
assign_public_ip:
description:
- 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.
required: false

ramdisk_id:
description:
- A RAM disk id for the instances.
required: false
version_added: "1.8"
instance_profile_name:
description:
- The name or the Amazon Resource Name (ARN) of the instance profile associated with the IAM role for the instances.
required: false
version_added: "1.8"
ebs_optimized:
description:
- Specifies whether the instance is optimized for EBS I/O (true) or not (false).
required: false
default: false
version_added: "1.8"
classic_link_vpc_id:
description:
- Id of ClassicLink enabled VPC
required: false
