Configuration

The following table describe available configuration values.

Variable	Purpose	Default/Description
SECRET	A 32 character long secure random secret used for encrypting some data inside the database. When data has been created inside the database, the secret cannot be changed anymore, otherwise decryption fails.	Not set by default, you need to explicitly set it, e.g., generate via openssl rand -hex 16

BASIC_AUTH_USER	For auth mode basic_single: Username for login	Not set by default, you need to explicitly set it to user name
BASIC_AUTH_PASSWORD	For auth mode basic_single: User's password for login	Not set by default, you need to explicitly set it to a secure random
BASIC_AUTH_CREDENTIALS	For auth mode basic_credentials: list of comma separated credentials, e.g. username1=password1,username2=password2	Not set by default, you need to explicitly set it

LOGGING_LEVEL	Logging level. Possible are debug, info, warn, error, dpanic, panic, fatal. Setting to debug enables high verbosity output.	Defaults to info
LOGGING_ENCODING	Logging encoding. Possible are console and json	Defaults to json
LOGGING_DIRECTORY	Logging directory. When set, logs will be added to a file called upda.log in addition to the standard output. Ensure that upda has access permissions. Use an external program for log rotation if desired.
