Create Auto Scaling groups using launch configurations
Important
Limitations:
-
As of January 1, 2023, new Amazon EC2 instance types are no longer supported in launch configurations. This includes support for any instance types added to an AWS Region after the initial Region launch.
-
Accounts created on or after June 1, 2023 cannot create new launch configurations using the console.
-
Accounts created on or after October 1, 2024 cannot create new launch configurations using any method (console, API, AWS CLI, or CloudFormation).
Migrate to launch templates to make sure 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.
