1. Prerequisites

Before you begin, make sure you have the following:

  • An account with the cloud provider you plan to use (e.g., AWS, Azure, Google Cloud).
  • Terminal or Command Prompt: You'll need a terminal or command prompt on your computer.

2. Installing tfenv

On macOS and Linux:

  1. Open a Terminal window.

  2. Install tfenv using a package manager. For example, on macOS using Homebrew:

    brew install tfenv

    On Linux, you can use the following commands:

    git clone https://github.com/tfutils/tfenv.git ~/.tfenv
echo 'export PATH="$HOME/.tfenv/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

3. Using tfenv

  1. Open a Terminal or Command Prompt.
  2. Navigate to the directory where you plan to work on your Terraform projects.

Installing Specific Terraform Version

To install a specific version of Terraform using tfenv, run the following command:

tfenv install <terraform_version>

For example:

tfenv install 0.15.5

Switching Between Installed Versions

To switch between different installed Terraform versions, use the following command:

tfenv use <terraform_version>

For example:

tfenv use 0.15.5

Listing Installed Versions

You can list all the Terraform versions that are installed using tfenv:

tfenv list

Automatically Switching Versions (Optional)

You can configure your project directory to automatically switch to a specific Terraform version by creating a .terraform-version file in the project directory. Inside the file, specify the desired Terraform version. When you navigate to that directory, tfenv will automatically switch to the specified version.

4. Conclusion

Congratulations! You've successfully installed tfenv and learned how to use it to manage multiple versions of Terraform on your system. This can be especially helpful when working on different projects that require different Terraform versions.

By using tfenv, you can avoid conflicts between projects with different version requirements and ensure a smooth development and deployment process.

For more information and detailed documentation, you can visit the tfenv GitHub repository: https://github.com/tfutils/tfenv

Remember that using the appropriate version of Terraform for each project is crucial for maintaining consistent and reliable infrastructure configurations.
