Retrieve userdata from launch template – Amazon web services

I have a launch template in my account which is being used by an autoscaling group.

Is there any way I can retrieve the userdata which is baked inside the template from either the console or the aws cli?

I could always login an instance and find it there but I’m wondering if this functionality is exposed somehow

    This is what I ended up using:

    aws ec2 describe-launch-template-versions --launch-template-id lt-123 --query 'LaunchTemplateVersions[0].LaunchTemplateData.UserData' --output text | base64 -d

    You can use AWS CLI’s describe-launch-template-versions which returns UserData.
