Step-by-Step Guide to Downgrade Terraform
Step 1: Check Current Terraform Version
First, you need to know your current Terraform version. Open your terminal and type:
This command will display the current version of Terraform installed on your system.
Step 2: Uninstall Current Terraform Version
Next, you need to uninstall the current version of Terraform. The uninstallation process varies depending on your operating system.
For macOS users:
If you installed Terraform using Homebrew, use the following command:
brew uninstall terraform
For Linux users:
If you installed Terraform by downloading a binary, you’ll need to remove the binary file. Typically, it’s located in the
/usr/local/bin directory. Use the following command:
sudo rm /usr/local/bin/terraform
For Windows users:
If you installed Terraform using Chocolatey, use the following command in PowerShell:
choco uninstall terraform
Step 3: Download Desired Terraform Version
After uninstalling the current version, you can download the version you want from the Terraform downloads page. Choose the appropriate package for your operating system and architecture.
Step 4: Install Desired Terraform Version
Once you’ve downloaded the desired version, you need to install it.
For macOS and Linux users:
Unzip the downloaded file and move the binary to
sudo mv terraform /usr/local/bin/
For Windows users:
Unzip the downloaded file and move the binary to a directory in your system’s PATH.
Step 5: Verify the Installation
Finally, verify that you’ve successfully downgraded Terraform by checking the version:
This command should now display the version you’ve just installed.
Backup Recommendations: Create backups of critical files and configurations before initiating the downgrade. This precautionary step can mitigate potential data loss or system misconfigurations.
Version Compatibility Warning: Ensure compatibility between the downgraded Terraform version and existing scripts/modules. A version mismatch could introduce unforeseen issues, and users should verify compatibility before proceeding.
Post-Downgrade Validation: Thoroughly validate the success of the downgrade by retesting their infrastructure provisioning processes. This ensures that the new Terraform version behaves as expected and that there are no lingering issues.
Downgrading Terraform to a previous version is a straightforward process if you follow these steps. Remember, it’s essential to understand why you’re downgrading and ensure that the version you’re switching to is compatible with your existing scripts and modules.
Whether you’re a data scientist, a DevOps professional, or a cloud engineer, mastering Terraform will help you manage your cloud resources more effectively. Stay tuned for more posts on Terraform and other data science tools!
