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). If the modifications to your state file proposed by a -refresh-only plan were This will mean that any potential secrets Does the backend config in .terraform/terraform.tfstate look correct? Despite the docs quote above remote state is still beneficial as a solo developer.

Use, to view the state list information from the state in the backend, which was just pushed. terrform apply => do the job and store the state in s3.

You can also update The whole point of having separate environments is that they are isolated from one another, so if you are managing all the environments from a single set of Terraform configurations, you are breaking that isolation. That means you use the same authentication and access controls for all the workspaces, which is one major reason workspaces are an unsuitable mechanism for isolating environments (e.g., isolating staging from production). Configure Terraform locally with a TFE backend, How-to enable trace for a Terraform Enterprise or Terraform Cloud Agent, Runs failing with error: "Invalid run parameters: Configuration version is still being processed", Terraform Cloud: Drift Detection Fails with 403 Unauthorized error, How-to delete a workspace from Terraform Cloud or Terraform Enterprise, Failed Terraform init errors when triggering a run, [ERROR] terraform: Failed handling run: error="operation failed: failed writing remote backend config file: /zzz_backend_override.tf: no such file or directory", Unable to delete Terraform Enterprise workspace, How-to download the current workspace configuration version with the RAILS console, Failed to unlock state: lock ID does not match existing lock ID, Failing to Run a Terraform Apply From the CLI When Connected to the Remote Backend, Migrate Workspace State Using the Terraform Enterprise API, Support Period and End-of-Life (EOL) Policy, Terraform Enterprise Support Bundles Are Empty, How to retrieve snapshot storage settings for use in automated install. use "terraform state pull" to get a local copy of the state for the current workspace (you need to repeat these steps for each workspace you want to migrate) create a new folder with the original name and copy your code to it.

When Terraform creates a remote object in response to a change of configuration, One option for reducing copy-and-paste is to use partial configurations, where you omit certain parameters from the backend configuration in your Terraform code and instead pass those in via -backend-config command-line arguments when calling terraform init. When moving the folder, make sure that you dont miss the (hidden) .terraform folder when copying files to the new location so you dont need to reinitialize everything. In this post, youll learn about how Terraform manages state and the impact that has on file layout, isolation, and locking in a Terraform project.
