Terraform version manager inspired by rbenv
Currently tfenv supports the following OSes
- macOS
- 64bit
- Arm (Apple Silicon)
- Linux
- 64bit
- Arm
- Windows (64bit) - only tested in git-bash - currently presumed failing due to symlink issues in git-bash
Install via Homebrew
brew install tfenv
Install via Arch User Repository (AUR)
yay --sync tfenv
Install via puppet
Using puppet module sergk-tfenv
include ::tfenv
- Check out tfenv into any path (here is
${HOME}/.tfenv
)
git clone --depth=1 https://github.com/tfutils/tfenv.git ~/.tfenv
- Add
~/.tfenv/bin
to your$PATH
any way you like
bash:
echo 'export PATH="$HOME/.tfenv/bin:$PATH"' >> ~/.bash_profile
zsh:
$ echo 'export PATH="$HOME/.tfenv/bin:$PATH"' >> ~/.zprofile
For WSL users:
echo 'export PATH=$PATH:$HOME/.tfenv/bin' >> ~/.bashrc
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
Install a specific version of Terraform.
If no parameter is passed, the version to use is resolved automatically via TFENV_TERRAFORM_VERSION environment variable or .terraform-version files, in that order of precedence, i.e. TFENV_TERRAFORM_VERSION, then .terraform-version. The default is 'latest' if none are found.
If a parameter is passed, available options:
x.y.z
Semver 2.0.0 string specifying the exact version to installlatest
is a syntax to install latest versionlatest:<regex>
is a syntax to install latest version matching regex (used by grep -e)latest-allowed
is a syntax to scan your Terraform files to detect which version is maximally allowed.min-required
is a syntax to scan your Terraform files to detect which version is minimally required.
See required_version docs. Also see min-required & latest-allowed section below.
$ tfenv install
$ tfenv install 0.7.0
$ tfenv install latest
$ tfenv install latest:^0.8
$ tfenv install latest-allowed
$ tfenv install min-required
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.
You can opt-in to using GnuPG tools for PGP signature verification if keybase is not available:
Where TFENV_INSTALL_DIR
is for example, ~/.tfenv
or /usr/local/Cellar/tfenv/<version>
echo 'trust-tfenv: yes' > ${TFENV_INSTALL_DIR}/use-gpgv
tfenv install
The trust-tfenv
directive means that verification uses a copy of the
Hashicorp OpenPGP key found in the tfenv repository. Skipping that directive
means that the Hashicorp key must be in the existing default trusted keys.
Use the file ${TFENV_INSTALL_DIR}/use-gnupg
to instead invoke the full gpg
tool and
see web-of-trust status; beware that a lack of trust path will not cause a
validation failure.
If you use a .terraform-version file, tfenv install
(no argument) will install the version written in it.
Please note that we don't do semantic version range parsing but use first ever found version as the candidate for minimally required one. It is up to the user to keep the definition reasonable. I.e.
// this will detect 0.12.3
terraform {
required_version = "<0.12.3, >= 0.10.0"
}
// this will detect 0.10.8 (the latest 0.10.x release)
terraform {
required_version = "~> 0.10.0, <0.12.3"
}
String (Default: amd64
)
Specify architecture. Architecture other than the default amd64 can be specified with the TFENV_ARCH
environment variable
Note: Default changes to arm64
for versions that have arm64 builds available when $(uname -m)
matches aarch64* | arm64*
TFENV_ARCH=arm64 tfenv install 0.7.9
String (Default: true)
Should tfenv automatically install terraform if the version specified by defaults or a .terraform-version file is not currently installed.
TFENV_AUTO_INSTALL=false terraform plan
terraform use <version that is not yet installed>
Integer (Default: 2)
Set the mechanism used for displaying download progress when downloading terraform versions from the remote server.
- 2: v1 Behaviour: Pass
-#
to curl - 1: Use curl default
- 0: Pass
-s
to curl
Integer (Default: 0)
Set the debug level for TFENV.
- 0: No debug output
- 1: Simple debug output
- 2: Extended debug output, with source file names and interactive debug shells on error
- 3: Debug level 2 + Bash execution tracing
String (Default: https://releases.hashicorp.com)
To install from a remote other than the default
TFENV_REMOTE=https://example.jfrog.io/artifactory/hashicorp
Integer (Default: 0)
When using a custom remote, such as Artifactory, instead of the Hashicorp servers,
the list of terraform versions returned by the curl of the remote directory may be inverted.
In this case the latest
functionality will not work as expected because it expects the
versions to be listed in order of release date from newest to oldest. If your remote
is instead providing a list that is oldes-first, set TFENV_REVERSE_REMOTE=1
and
functionality will be restored.
TFENV_REVERSE_REMOTE=1 tfenv list-remote
Path (Default: $TFENV_ROOT
)
The path to a directory where the local terraform versions and configuration files exist.
TFENV_CONFIG_DIR="$XDG_CONFIG_HOME/tfenv"
String (Default: "")
If not empty string, this variable overrides Terraform version, specified in .terraform-version files.
latest
and latest:<regex>
syntax are also supported.
tfenv install
and tfenv use
command also respects this variable.
e.g.
TFENV_TERRAFORM_VERSION=latest:^0.11. terraform --version
String (Default: "")
If not empty string, this variable specifies the credentials file used to access the remote location (useful if used in conjunction with TFENV_REMOTE).
e.g.
TFENV_NETRC_PATH="$PWD/.netrc.tfenv"
Integer (Default: 1)
To disable colouring of console output, set to 0.
String (Default: +%F %T)
The display format for the date as passed to the date
binary to generate a datestamp used as a prefix to:
FILE
type log file lines.- Each console output line when
BASHLOG_EXTRA=1
Integer (Default: 0)
By default, console output from tfenv does not print a date stamp or log severity.
To enable this functionality, making normal output equivalent to FILE log output, set to 1.
Integer (Default: 0)
Set to 1 to enable plain text logging to file (FILE type logging).
The default path for log files is defined by /tmp/$(basename $0).log Each executable logs to its own file.
e.g.
BASHLOG_FILE=1 tfenv use latest
will log to /tmp/tfenv-use.log
String (Default: /tmp/$(basename ${0}).log)
To specify a single file as the target for all FILE type logging regardless of the executing script.
String (Default: "")
BE CAREFUL - MISUSE WILL DESTROY EVERYTHING YOU EVER LOVED
This variable allows you to pass a string containing a command that will be executed using eval
in order to produce a prefix to each console output line, and each FILE type log entry.
e.g.
BASHLOG_I_PROMISE_TO_BE_CAREFUL_CUSTOM_EVAL_PREFIX='echo "${$$} "'
will prefix every log line with the calling process' PID.
Integer (Default: 0)
Set to 1 to enable JSON logging to file (JSON type logging).
The default path for log files is defined by /tmp/$(basename $0).log.json Each executable logs to its own file.
e.g.
BASHLOG_JSON=1 tfenv use latest
will log in JSON format to /tmp/tfenv-use.log.json
JSON log content:
{"timestamp":"<date +%s>","level":"<log-level>","message":"<log-content>"}
String (Default: /tmp/$(basename ${0}).log.json)
To specify a single file as the target for all JSON type logging regardless of the executing script.
Integer (Default: 0)
To log to syslog using the logger
binary, set this to 1.
The basic functionality is thus:
local tag="${BASHLOG_SYSLOG_TAG:-$(basename "${0}")}";
local facility="${BASHLOG_SYSLOG_FACILITY:-local0}";
local pid="${$}";
logger --id="${pid}" -t "${tag}" -p "${facility}.${severity}" "${syslog_line}"
String (Default: local0)
The syslog facility to specify when using SYSLOG type logging.
String (Default: $(basename $0))
The syslog tag to specify when using SYSLOG type logging.
Defaults to the PID of the calling process.
Switch a version to use
If no parameter is passed, the version to use is resolved automatically via .terraform-version files or TFENV_TERRAFORM_VERSION environment variable (TFENV_TERRAFORM_VERSION takes precedence), defaulting to 'latest' if none are found.
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)
min-required
will switch to the version minimally required by your terraform sources (see above tfenv install
)
$ tfenv use
$ tfenv use min-required
$ tfenv use 0.7.0
$ tfenv use latest
$ tfenv use latest:^0.8
Note: tfenv use latest
or tfenv use latest:<regex>
will find the latest matching version that is already installed. If no matching versions are installed, and TFENV_AUTO_INSTALL is set to true
(which is the default) the the latest matching version in the remote repository will be installed and used.
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
List installed versions
$ tfenv list

If you put a .terraform-version
file on your project root, or in your home directory, tfenv detects it and uses the version written in it. If the version is latest
or latest:<regex>
, the latest matching version currently installed will be selected.
Note, that TFENV_TERRAFORM_VERSION environment variable can be used to override version, specified by .terraform-version
file.
$ cat .terraform-version
