EFS: Lookup for filesystems by name

[Balaji-JBC]

Describe the feature

Whenever we want to use an existing EFS, we have to refer it by arn or ID. Why not have a look up that returns list of filesystems and we can continue with it

Use Case

First time i deploy, i expect the EFS to be created fresh. Second time when i deploy a stack, i want to code like if this filesystem with the given name already exists, use it, like that. But not able to do as as arn/filesystemid is mandatory

Proposed Solution

Have a lookup function which returns array of file systems available with the given name

I'm not sure I understand, if you want to create a new FileSystem and have your stack control that FileSystem, then you want to use new FileSystem(...). Also, how would a list of FileSystems be used exactly especially in this use case?

Hi,
I would like to have a cdk code as follows

1. Define a file system configuration with a file_system_name
2. If the file_system_name doesn't already exist, create a new one.
3. else if the file_system_name already exists, get that file system, modify it's properties if needed and deploy

since, file_system_name is not unique, I was expecting a function that returns array of file_system having the given file_system_name and I can work accordingly on them

You need to either have your stack manage a resource (new XXX), or create a proxy class for an existing resource to pass that information into resources your stack will manage (construct.fromXxx). You cannot have both at once while still using CDK the way it was meant to be used
