Packer
Install Packer
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.
- Using your system's package manager.
Installing Packer
Retrieve the packer binary by downloading a pre-compiled binary or compiling it from source.
To install the precompiled binary, download the appropriate package for your system. Packer is currently packaged as a zip file.
After downloading Packer, unzip the package. Packer runs as a single
binary named packer
.
Finally, make sure that the packer
binary is available on your PATH
. This process will differ depending on your operating system.
Print a colon-separated list of locations in your PATH
.
$ echo $PATH
Move the Packer binary to one of the listed locations. This command assumes that the binary is currently in your downloads folder and that your PATH
includes /usr/local/bin
, but you can customize it if your locations are different.
$ mv ~/Downloads/packer /usr/local/bin/
For more detail about adding binaries to your path, see this Stack Overflow article.
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
console creates a console for testing variable interpolation
fix fixes templates from old versions of packer
fmt Rewrites HCL2 config files to canonical format
hcl2_upgrade transform a JSON template into an HCL2 configuration
init Install missing plugins or upgrade plugins
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 set up 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!
Troubleshooting
On some distributions, there may be another tool named packer
installed by
default. The following error indicates that there is a name conflict.
$ packer
/usr/share/cracklib/pw_dict.pwd: Permission denied
/usr/share/cracklib/pw_dict: Permission denied
Note
On Arch Linux, there is a package named packer
in the main
repository and in the AUR. The package packer
in the AUR is an old
name for a package management tool for Arch, it's not HashiCorp
Packer.
To fix this, create a symlink to packer
that uses a different name like
packer.io
, or invoke the packer
binary you want using its absolute path,
e.g. /usr/local/packer
.
