Environment Variables for Packer

Packer uses a variety of environmental variables. A listing and description of each can be found below:

PACKER_CACHE_DIR - The location of the packer cache.
PACKER_CONFIG - The location of the core configuration file. The format of the configuration file is basic JSON. See the core configuration page.
PACKER_LOG - Setting this to any value other than "" (empty string) or "0" will enable the logger. See the debugging page.
PACKER_LOG_PATH - The location of the log file. Note: PACKER_LOG must be set for any logging to occur. See the debugging page.
PACKER_NO_COLOR - Setting this to any value will disable color in the terminal.
PACKER_PLUGIN_MAX_PORT - The maximum port that Packer uses for communication with plugins, since plugin communication happens over TCP connections on your local host. The default is 25,000. See the core configuration page.
PACKER_PLUGIN_MIN_PORT - The minimum port that Packer uses for communication with plugins, since plugin communication happens over TCP connections on your local host. The default is 10,000. See the core configuration page.
CHECKPOINT_DISABLE - When Packer is invoked it sometimes calls out to checkpoint.hashicorp.com to look for new versions of Packer. If you want to disable this for security or privacy reasons, you can set this environment variable to 1.
TMPDIR (Unix) / TMP TEMP USERPROFILE (Windows) - The location of the directory used for temporary files (defaults to /tmp on Linux/Unix and %USERPROFILE%\AppData\Local\Temp on Windows Vista and above). It might be necessary to customize it when working with large files since /tmp is a memory-backed filesystem in some Linux distributions in which case /var/tmp might be preferred.
TMPDIR_SUFFIX - When set, packer will put temporary files under system temporary directory + TMPDIR_SUFFIX. This allows to create & to give specific rights to a directory ie: chmod 777 $TMPDIR/$TMPDIR_SUFFIX/
