Create Auto Scaling groups using launch configurations
Important
You can not call CreateLaunchConfiguration with new Amazon EC2 instance types that are
released after December 31, 2022. In addition, any new accounts
created on or after June 1, 2023 will not have the option to create
new launch configurations through the console. In the future, new accounts will not be able to create
new launch configurations by using the console, API, CLI, and CloudFormation. Migrate to launch templates
to ensure that you don’t need to create new launch configurations now or in the future. For information
about migrating your Auto Scaling groups to launch templates, see
Migrate your Auto Scaling groups to launch
templates.
If you have created a launch configuration or an EC2 instance, you can create an Auto Scaling group that uses a launch configuration as a configuration template for its EC2 instances. The launch configuration specifies information such as the AMI ID, instance type, key pair, security groups, and block device mapping for your instances. For information about creating launch configurations, see Create a launch configuration.
You must have sufficient permissions to create an Auto Scaling group. You must also have sufficient permissions to create the service-linked role that Amazon EC2 Auto Scaling uses to perform actions on your behalf if it does not yet exist. For examples of IAM policies that an administrator can use as a reference for granting you permissions, see Identity-based policy examples.
