CodeDeploy to update Auto scaling launch template

Question

Hi,
Is this possible to update the auto scaling group launch template with new code built with aws code build and I need to deploy that new code via codedeploy to a launch instance.
Here I already had the auto scaling group and launch template.
I need a example Cloud formation script to build the above solution

Hello.

Why not just deploy the code directly to EC2 in the AutoScaling group instead of updating the launch template?  
https://docs.aws.amazon.com/codedeploy/latest/userguide/deployment-groups-create-blue-green.html

Blue/Green deployment of AutoScaling groups is not supported by CloudFormation, so you will need to create Lambda etc. as shown in the blog below.

Hello,

I'm no expert, but I think all you have to do is rename your CodeDeploy.

CloudFormation will create a new CodeDeploy for you by keeping resources that are currently in use.
Of course, make sure you don't rename your other resources.

For exemple, if tou have this code:

```
MyDeploy: 
  Type: AWS::CodeDeploy::Application 
  Properties:
    ComputePlatform: Lambda
```

You can do that:

```
MyDeploy2: 
  Type: AWS::CodeDeploy::Application 
  Properties:
    ComputePlatform: Lambda
```

**Please don't rename other ressources because CloudFormation will destroy and create new ones.**

@Riku_Kobayashi Can you tell me if I'm wrong or not? (It's my first comment on re:Post)
