**Tell us about your request**
Hi,
I love Fargate.
I'm experimenting EKS on Fargate.
Migrate Managed Nodes to Fargare.
No change yaml, But All Pod are running...!!
It's coooool! Thank you.

But I have some problems.
Fargate with VPA 3 times costs than Managed Nodes (Running 2X `t3.medium`)
So, I get running fargete spec...
Oh, no! There is no method to get running Fargate spec.
So, Please Support Get Running Fargate spec API!

**Which service(s) is this request for?**
EKS on Fargate

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
There is no method to get running Fargate spec.

So, Please support get running Fargate spec API
or
`kubectl get node fargare-xxx` can check running Fargate spec now.

**Are you currently working around this issue?**
I was frightened to check Daily aws cost report.

**Additional context**
No, Thank you.

**Attachments**
No, Thank you.

Start by reviewing the EKS on Fargate service APIs and the node information currently visible through `kubectl get node fargare-xxx`. Clarify which running Fargate specification fields are required and whether the request belongs in an existing AWS API. Done means a defined, supported way to retrieve the running Fargate specification.
