Prefect Community

hey guys, I’m trying to `prefect deployment build` with `-sb` on S3 and `-ib` of a DockerContainer, then I got
```botocore.exceptions.ClientError: An error occurred (AccessDenied) when calling the PutObject operation: Access Denied```
I guess it has to do with the IAM role, but I don’ know how to switch/use a IAM role during `deployment build`, any ideas?

your S3 block needs explicit credentials on the block to work with docker ib

since I build the deployment on local, I realize that I need to do `assume-role` to switch my IAM role, then prefect can build and upload the artifacts from my local to s3
