如何从VPC中的Lambda调用AWS Rekognition

Question

I am working on a lambda function that needs to access RDS , S3 and Rekognition services from AWS.

I gave S3 and Rekognition permissions via the AmazonS3FullAccess and the AmazonRekognitionFullAccess policies respectively and it worked fine

The thing is that I could not access my Aurora instance inside RDS because it's inside a VPC

I changed my lambda network configurations so it would be able to access the VPC, and the Aurora connection worked as expected, but then the connection to Rekognition stopped working, whenever I invoke detectLabels for example it just hangs.

Am I missing some permission?

If you have no outside connection then you'll need to create an internet gateway through the VPC via NAT.

AWS has documentation for it, and there's a bit more discussion in another StackOverflow question .
