Enable AWS RDS Auto Scaling via Cloudformation

Question

I have RDS instances running in my AWS account created via a Cloudformation template. Recently there was a storage-full occurrence and as immediate remediation, I modified storage size from default 20 GB to 50 GB from the console.

Now I am considering modifying my CFN template so that RDS auto-scaling is enabled. But as I went through the AWS documentation, it says auto-scaling can be enabled through CLI, RDS API, and Console, and no mention about Cloudformation?

Is there any way to enable auto-scaling via Cloudformation?

Answer 1

There is not direct option for that, as explained in the following GitHub issue:

• AWS::RDS::DBInstance (add Storage Auto Scaling)

However, it seems that if you set MaxAllocatedStorage, the storage autoscaling will get enabled.
