# Environmental 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](/docs/other/core-configuration.html).
|
|
|
|
* `PACKER_LOG` - Setting this to any value will enable the logger.
|
|
See the [debugging page](/docs/other/debugging.html).
|
|
|
|
* `PACKER_LOG_PATH` - The location of the log file. Note: `PACKER_LOG` must
|
|
be set for any logging to occur. See the [debugging page](/docs/other/debugging.html).
|
|
|
|
* `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](/docs/other/core-configuration.html).
|
|
|
|
* `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](/docs/other/core-configuration.html).
