To make this work, you had to use a two-step process: If you ever wanted to delete the S3 bucket and DynamoDB table, youd have to do this two-step process in reverse: This two-step process is a bit awkward, but the good news is that you can share a single S3 bucket and DynamoDB table across all of your Terraform code, so youll probably only need to do it once (or once per AWS account if you have multiple accounts). But when I tried renaming the file to statefile.tf, I seem to be hitting a different roadblock now. it will record the identity of that remote object against a particular To allow for recovery, the state has been written to the file "errored.tfstate" in the current working directory.
