Synchronizing Remote Terraform Backend States

Posted on | Edited on |

Introduction

When cloning a project from a remote source, it’s crucial to synchronize the Terraform states from the backend to maintain consistency and accuracy.

Syncing Remote Backend State: A Quick Guide

Follow these steps to efficiently sync your remote backend state:

1. Initialize and Install Dependencies

First, initiate the process and update dependencies using the following command:

1
2
3
4
terraform init

# If you need to upgrade dependencies
terraform init --upgrade

2. Streamline Variable Input

Instead of manually inputting or exporting variables each time, simplify the process by creating a terraform.tfvars file:

1
echo "foo=bar" > terraform.tfvars

3. Removing Items Not Present in Remote

In cases where items are removed from the remote but haven’t been reflected in the state, use the following command:

1
terraform state rm <resource>.<name>

4. Importing New Items to Sync State

If new items have been added but aren’t yet synced with the state, consult the provider’s documentation to confirm import support. Then use the provided syntax:

1
terraform import <resource>.<name> <id>

Conclusion

Properly synchronizing Terraform backend states ensures your project’s integrity and consistency, especially when working with remote repositories. Following these concise steps will streamline your workflow and enhance your overall development process.
