Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. A launch template is a resource that contains the configuration information to launch an instance, such as the AMI ID, instance type, key pair, security groups, and network configurations.
When attempting to launch an EC2 instance using a launch template, you may encounter the error: InvalidLaunchTemplateName.NotFound. This indicates that the specified launch template name does not exist or is incorrect.
This error typically occurs when the launch template name is misspelled, the template has been deleted, or it exists in a different AWS region than expected.
The InvalidLaunchTemplateName.NotFound error is an indication from AWS that the launch template you are trying to use cannot be found. This could be due to a typo in the template name, or the template might have been removed or is not available in the current region.
Launch templates are region-specific, meaning they are only available in the region they were created. If you attempt to use a launch template in a different region, AWS will not be able to find it.
To resolve the InvalidLaunchTemplateName.NotFound error, follow these steps:
To list all launch templates in a specific region, use the AWS CLI command:
aws ec2 describe-launch-templates --region
This command will return a list of all launch templates available in the specified region. Verify that your launch template is listed.
For more information on managing launch templates, visit the AWS EC2 Launch Templates Documentation.
