Packer may be installed in the following ways:
Using a precompiled binary; We release binaries for all supported platforms and architectures. This method is recommended for most users.
Installing from source This method is only recommended for advanced users.
An unoffical alternative installation method
To install the precompiled binary, download the appropriate package for your system. Packer is currently packaged as a zip file. We do not have any near term plans to provide system packages.
Next, unzip the downloaded package into a directory where Packer will be
installed. On Unix systems,
/usr/local/packer is generally good,
depending on whether you want to restrict the install to just your user or
install it system-wide. If you intend to access Packer from the command-line, make
sure to place it somewhere on your
PATH. On Windows systems, you can install
the binary wherever you'd like. The single
Windows) binary contains all that is necessary to run Packer.
After unzipping the package, the directory should contain a single binary
packer. The final step to
installation is to make sure the directory you installed Packer to is on the
PATH. See this
for instructions on setting the PATH on Linux and Mac. This
contains instructions for setting the PATH on Windows.
»Compiling from Source
Clone the Packer repository from GitHub into your
mkdir -p $(go env GOPATH)/src/github.com/hashicorp && cd $_ git clone https://github.com/hashicorp/packer.git cd packer
Build Packer for your current system and put the binary in
./bin/(relative to the git checkout). The
make devtarget is just a shortcut that builds
packerfor only your local build environment (no cross-compiled targets).
»Verifying the Installation
After installing Packer, verify the installation worked by opening a new command
prompt or console, and checking that
packer is available:
$ packer usage: packer [--version] [--help] <command> [<args>] Available commands are: build build image(s) from template fix fixes templates from old versions of packer inspect see components of a template validate check that a template is valid version Prints the Packer version
If you get an error that
packer could not be found, then your PATH environment
variable was not setup properly. Please go back and ensure that your PATH
variable contains the directory which has Packer installed.
Otherwise, Packer is installed and you're ready to go!
»Alternative Installation Methods
While the binary packages are the only official method of installation, there are alternatives available.
If you're using OS X and Homebrew, you can install Packer by running:
$ brew install packer
If you're using Windows and Chocolatey, you can install Packer by running:
choco install packer
On some RedHat-based Linux distributions there is another tool named
installed by default. You can check for this using
which -a packer. If you get
an error like this it indicates there is a name conflict.
$ packer /usr/share/cracklib/pw_dict.pwd: Permission denied /usr/share/cracklib/pw_dict: Permission denied
To fix this, you can create a symlink to packer that uses a different name like
packer.io, or invoke the
packer binary you want using its absolute path,
