I m in a ComponentResource constructor so no await async I m creating a volume but I conditionally I want to provide an initial snapshot IF the snapshot exists I m using aws ebs getSnapshot But that returns a promise How would I supply a snapshotId to aws ebs Volume

there s `aws ebs getSnapshotOutput`

if you don t want to use that do it inside an `apply`

``` const volumeName = `$ args instanceData name volume` gt gt const foundSnapshot = aws ebs getSnapshotOutput filters name tag Name values volumeName mostRecent true owners self const volume = new aws ebs Volume volumeName size args instanceData volumeSize availabilityZone args instanceData availabilityZone tags Name `$ args instanceData name volume` ProjectIdentifier Platform Environment args stack snapshotId foundSnapshot parent this ```

I e will the above work if there s no snapshot

billowy-army-68599 · Answer

if the snapshot doesn t exist in the cloud provider then it ll fail if you don t know if it exists you should create it using a resource

damp-painting-47843 · Answer

In the beginning there may be no snapshot The snapshot is a final snapshot from a previous destroy

Basically I m trying to say if it s never been destroyed before create a new volume if not create a volume from this snapshot

damp-painting-47843 · Answer

Perhaps the solution is to do this outside of the component

damp-painting-47843 · Answer

Get the snapshot outside of the component where you can use try catch and await And then supply it to the component

damp-painting-47843 · Answer

But it would be nice to have it all encapsulated

billowy-army-68599 · Answer

yeah outside the component is the way to do it just have the snapshot id as an argument input
