Using an existing S3 bucket in AWS SAM template

Question

I am using AWS SAM template for deployment of python AWS lambdas. The trigger for these functions are from existing S3 buckets. But in SAM template I am unable to use existing buckets (only new bucket creation is supported), hence I'am creating the trigger manually.

Is there any way we could incorporate this in SAM template ?

Not sure about sam, but since sam is based on cloudformation (CFN), maybe you could import it? CFN supports importing buckets into stacks. – Elin

you can't use an existing bucket with sam. It's a limitation mention here. You can try the workaround from this comment. – Hanzelin

In 2024, Just trying to understand it is still a restriction with SAM. If someone know an update, please help – Ecosphere
