pkenv

Packer version manager mainly inspired by tfenv

Support

Currently pkenv supports the following OSes

• Linux (64bit)
• Mac OS X (64bit)
• Arm
• Windows - tested in Cygwin and WSL.

Installation

On Mac OS X, you can install pkenv with Homebrew:

$ brew tap kwilczynski/homebrew-pkenv
$ brew install pkenv

On any other platform, you can install pkenv as follows:

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

$ git clone https://github.com/iamhsa/pkenv.git ${HOME}/.pkenv

2. Add ${HOME}/.pkenv/bin to your $PATH any way you like

$ echo 'export PATH="${HOME}/.pkenv/bin:$PATH"' >> ${HOME}/.bash_profile

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

$ ln -s ${HOME}/.pkenv/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 ~/.pkenv/bin/* ~/.local/bin
$ command -v pkenv

Usage

pkenv install [version]

Install a specific version of Packer. Available options for version:

• i.j.k exact version to install
• latest is a syntax to install latest version
• latest:<regex> is a syntax to install latest version matching regex (used by grep -e)

$ pkenv install 1.1.1
$ pkenv install latest
$ pkenv install latest:^1.3
$ pkenv install

If shasum is present in the path, pkenv 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:

$ echo 'trust-pkenv: yes' > ~/.pkenv/use-gpgv
$ pkenv install

The trust-pkenv directive means that verification uses a copy of the Hashicorp OpenPGP key found in the pkenv repository. Skipping that directive means that the Hashicorp key must be in the existing default trusted keys. Use the file ~/.pkenv/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.

.packer-version

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

Specify architecture

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

PKENV_ARCH=arm pkenv install 1.3.1

pkenv use

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)

$ pkenv use 0.12.3
$ pkenv use latest
$ pkenv use latest:^0.12

pkenv uninstall

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

$ pkenv uninstall latest
$ pkenv uninstall latest:^0.8

.packer-version

If you put .packer-version file on your project root, or in your home directory, pkenv 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 .packer-version
1.4.2

$ packer --version

$ echo 1.4.2 > .packer-version
