How to Assign Sequential Names to EC2 Instances in AWS Auto-Scaling Group?

Question

Question:

Hi,

I'm using AWS Auto Scaling Groups (ASG) to manage my EC2 instances. Currently, all instances get the same name, but I need each instance to have a unique, sequential name like Instance-1, Instance-2, etc.

Current Setup:

• AWS Auto Scaling launches and manages EC2 instances.

• Instances receive the same name from the launch configuration.

Requirement:

• Unique, sequential instance names.

Challenges:

• AWS ASG doesn't support sequential naming natively.

• Need a reliable method to dynamically assign and maintain these names.

Attempts So Far:

• Tagging instances post-launch using AWS CLI scripts.

• Considering AWS Lambda with CloudWatch Events for lifecycle hooks but unsure about managing the sequence.

Questions:

1. Best practices for assigning sequential names in ASG?

2. How to implement a reliable solution for this?

3. Are there AWS services to simplify this process?

4. Any example implementations or guides?

Thanks for your help!
