Refer to the following command for installation: For MacOS we are going to use the brew package manager. Lets first see how we can install tfenv on MacOS. Keep in mind it is not an official tool by HashiCorp. Tfenv is a versioning tool for Terraform, maintained by the open source community on Github, under the MIT Open source license. OpenTofu is the future of the Terraform ecosystem, and having a truly open-source project to support all your IaC needs is the main priority.īefore we go into the installation part of tfenv let’s first see what tfenv is. OpenTofu retained all the features and functionalities that had made Terraform popular among developers while also introducing improvements and enhancements. It is a viable alternative to HashiCorp’s Terraform, being forked from Terraform version 1.5.6. OpenTofu is an open-source version of Terraform that will expand on Terraform’s existing concepts and offerings. Note: New versions of Terraform will be placed under the BUSL license, but everything created before version 1.5.x stays open-source. In this post, we will see how you can install Terraform, as well as how to upgrade it to a specific release version (Terraform v0.15, v0.14, v0.13, v0.12, or any other) using tfenv. Similarly, you can upgrade to the next stable version so that your Terraform stack is up to date. If during the testing phase there is a bug which breaks the existing infrastructure setup, tfenv can help roll back Terraform to the previous stable version. On the other hand, development, test, and sometimes staging environments receive newer versions of any software package. As a rule of thumb, the production environment gets the most stable version. Just like a versioning tool such as Git or SVN, which allows you to rollback or upgrade if there is a problem with the current version of your code, tfenv lets you upgrade as well as rollback versions of Terraform.īut why do we need multiple versions of Terraform? A typical infrastructure setup always consists of development, testing, staging, and the production environment.
