Is there a way to attach a

DockerImageFunction

to a Bucket notification? I’m getting:

Copy code

Type 'DockerImageFunction' is not assignable to type 'FunctionDefinition'.
  Type 'DockerImageFunction' is missing the following properties from type 'Function': _isLiveDevEnabled, localId, attachPermissions, getConstructMetadata ts(2322)

Currently

sst.Bucket

only takes

sst.Function

notifications.

That said, you can do this with CDK code:

Copy code

const bucket = new sst.Bucket(...);

const function = // create a DockerImageFunction

bucket.s3Bucket.addEventNotification(s3.EventType.OBJECT_CREATED, new s3n.LambdaDestination(function));

Works great. Thanks. As a side question related to DockerImageFunction - Is there some helper to create a role for an array of permissions? DockerImageFunction takes a role as a prop. I can’t specify

permissions: [this.table, this.rds, this.bucket],

like we do for the others functions. I wonder if there is a easy way to use that helper and then to get the role. Currently, we create an sst.Function (that we need and happens to be very similar) and then we set the role

role: myOtherSimilarFunction.role

and it works well

Yeah the

permissions: […]

syntax is very specific to SST functions. The workaround you did is probably the best way to go.
