Terraform version manager inspired by rbenv

Currently tfenv supports the following OSes

• Mac OS X (64bit)
• Linux
• 64bit
• Arm
• Windows (64bit) - only tested in git-bash

Install via Homebrew

$ brew install tfenv

Install via puppet

Using puppet module sergk-tfenv

include ::tfenv

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

$ git clone https://github.com/kamatama41/tfenv.git ~/.tfenv

2. 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

Install a specific version of Terraform
latest is a syntax to install latest version latest:<regex> is a syntax to install latest version matching regex (used by grep -e)

$ tfenv install 0.7.0
$ tfenv install latest
$ tfenv install latest:^0.8

If shasum is present in the path, tfenv will verify the download against Hashicorp's published sha256 hash. If keybase is available in the path it will also verify the signature for those published hashes using hashicorp's published public key.

If you use .terraform-version, tfenv install (no argument) will install the version written in it.

Architecture other than the default amd64 can be specified with the TFENV_ARCH environment variable

TFENV_ARCH=arm tfenv install 0.7.9

Switch a version to use latest is a syntax to use the latest installed version latest:<regex> is a syntax to use latest installed version matching regex (used by grep -e)

$ tfenv use 0.7.0
$ tfenv use latest
$ tfenv use latest:^0.8

Uninstall a specific version of Terraform latest is a syntax to uninstall latest version latest:<regex> is a syntax to uninstall latest version matching regex (used by grep -e)

$ tfenv uninstall 0.7.0
$ tfenv uninstall latest
$ tfenv uninstall latest:^0.8

If you put .terraform-version file on your project root, tfenv detects it and use the version written in it. If the version is latest or latest:<regex>, the latest matching version currently installed will be selected.

$ 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Your version of Terraform is out of date!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

$ git --git-dir=~/.tfenv/.git pull

$ rm -rf /some/path/to/tfenv

• tfenv itself
• rbenv
  • tfenv partially uses rbenv's source code
