The Hanko backend can be configured using a yaml configuration file or using environment variables.
Environment variables have higher precedence than configuration via file (i.e. if provided, they overwrite the values
given in the file - multivalued options, like arrays, are also not merged but overwritten entirely).
The schema for the configuration file is given below. To set equivalent environment variables, join keys by _
(underscore) and uppercase the keys, i.e. for server.webauthn.relying_party.origins
use:
export SERVER_WEBAUTHN_RELYING_PARTY_ORIGINS="https://hanko.io,android:apk-key-hash:nLSu7w..."## Hanko Service configuration ##
#
server:

# You can use this list for key rotation: add a new key to the beginning of the list and the corresponding
# JWK will then be used for signing JWTs. All tokens signed with the previous JWK(s) will still
# be valid until they expire. Removing a key from the list does not remove the corresponding
# database record. If you remove a key, you also have to remove the database record, otherwise
# application startup will fail.
