Most Kegbot features and behaviors are controlled within the web application by using your admin account. However, a handful of settings are managed outside of the web application, and are described here.

Available settings

These values can be set in the shell environment of the server program.


Controls debug mode and other settings. Should be production in production; default debug.


Filesystem path where Kegbot-specific data is stored and managed. Default: /kegbot-data.


Credentials to the Kegbot database. Should be a value of the form mysql://USER:PASSWORD@HOST:PORT/NAME or postgres://USER:PASSWORD@HOST:PORT/NAME. PORT and PASSWORD are optional.

Example: mysql://kegbot@localhost/kegbot


The “From:” address to use in emails from the system. No default.


SMTP configuration URL. Should be a value in the form smtp://USER:PASSWORD@HOST:PORT or submission://USER:PASSWORD@HOST:PORT. Make sure to URL encode any special characters in USER and PASSWORD.

Gmail Example: submission:// Local Relay Example: smtp:


URL to the Kegbot Redis instance, in the format redis://:PASSWORD@HOST:PORT/DATABASE. PASSWORD and PORT are optional.

Example: redis://localhost/0


A random value, like a password, that will be used to generate and protect certain values used by the web service, such as cookies. Changing this value will cause all users to be logged out and will invalidate any pending invitations. Generally, you should only change this value if it has become compromised.


If set, a random value, like a password, that will always be accepted as an API key. As the name suggests, it is insecure to use this feature, which is intended only for use in special standalone/embedded installs (e.g. a single-user, offline Raspberry Pi) where there is no risk of exposure.


If set to true, the server will enable “setup mode”. The server can only be configured and upgraded when this mode is enabled. For security reasons, this mode is disabled by default and must be explicitly enabled by an administrator.

Configuration file

If you prefer, settings may be given in a config file instead. The configuration file must be located at $KEGBOT_DATA_DIR/kegbot.cfg.

The format is an INI-style config file with a single section named config. Any environment value may be given as a key in this section (with the exception of KEGBOT_DATA_DIR, which can never be read from this file).

Here is an example config file:

KEGBOT_SECRET_KEY = my-1337-s3kr3t
KEGBOT_DATABASE_URL = mysql://my_user@localhost:password/kegbot_test
KEGBOT_REDIS_URL = redis://localhost/0

Precedence of settings

When a value is specified in both the environment and the config file, the value from the environment takes precedence.
