Switching between different/multiple terraform versions

2022, Jun 06    

Prerequisites

This can be achieved with an OS tool called tfenv

Currently tfenv supports the following OSes

  • Mac OS X (64bit)
  • Linux ( 64bit and Arm )
  • Windows (64bit) - only tested in git-bash - currently presumed failing due to symlink issues in git-bash

Install tfenv via Homebrew for MacOS

brew install tfenv

How to use

Check if tfenv is properly installed

tfenv version

Pick the terraform version you want and use the tfenv install command :

List remotes :

  tfenv list-remote

As alternative, for checking available terraform versions you can check the list in here :

https://releases.hashicorp.com/terraform /

tfenv install 0.15.1

Use the terraform version you’ve just installed

tfenv use 0.15.1

Check that proper terraform version is used

terraform --version

List all currently installed terraform versions :

tfenv list

For windows (git-bash):

Check out tfenv into any path (here is ${HOME}/.tfenv)

git clone https://github.com/tfutils/tfenv.git ~/.tfenv

Add ~/.tfenv/bin to your $PATH any way you like

$ echo 'export PATH="$HOME/.tfenv/bin:$PATH"' >> ~/.bash_profile

OR you can make symlinks for tfenv/bin/* scripts into a path that is already added to your $PATH (e.g. /usr/local/bin) OSX/Linux Only!

ln -s ~/.tfenv/bin/* /usr/local/bin

On Ubuntu/Debian

Touching /usr/local/bin might require sudo access, but you can create ${HOME}/bin or ${HOME}/.local/bin and on next login it will get added to the session $PATH or by running . ${HOME}/.profile it will get added to the current shell session’s $PATH.

mkdir -p ~/.local/bin/
. ~/.profile
ln -s ~/.tfenv/bin/* ~/.local/bin
which tfenv
