Auto selection of Terraform version
Tired of always switching terraform version every time you changed project or even folder ?
.terraform-version file inside your terraform project with the required version.
Tfenv will specifically read this file and automatically change the Terraform version for you.
$ cat .terraform-version 0.6.16 $ terraform --version Terraform v0.6.16 Your version of Terraform is out of date! The latest version is 0.7.3. You can update by downloading from www.terraform.io $ echo 0.7.3 > .terraform-version $ terraform --version Terraform v0.7.3 $ echo latest:^0.8 > .terraform-version $ terraform --version Terraform v0.8.8
With all of this commands you'll be able to manage all of your terraform projects without having to change a single time your Terraform version. Everything can be automated in a few lines of codes with the simple addition of the
.terraform-version file. Please let me know if you've found a better tool to manage your Terraform versions in the commentary. I'll be more than happy to update my article.
