Description

It's often useful to include a description when publishing a new Lambda function. For example, this can be used to specify the source control reference that the Lambda function was deployed from.

terraform-provider-aws/internal/service/lambda/function.go

Lines 1226 to 1228 in f45acbb

	versionReq := &lambda.PublishVersionInput{
	FunctionName: aws.String(d.Id()),
	}

This is not possible with the current implementation.

New or Affected Resource(s)

• aws_lambda_function

Potential Terraform Configuration

resource "aws_lambda_function" "function" {
  publish = true
  version_description = "Published by ${var.user} from ${var.source_revision}"
}

Encountered this issue this week.

I did notice that if you set the description on the lambda itself (i.e. the description field on aws_lambda_function resource), it'll magically show up in the description of the alias.
