Server: Configuration

All configurations are set using environment variables. Creating a .env.docker file is recommended to store all the environment variables required to run the server.

The following sections describe the environment variables required to run the server.

Environment Variables

Attestations and Assertions require a valid RP_NAME, HOSTNAME, and ORIGIN to be set. ORIGIN and HOSTNAME must be set to a valid domain secured with HTTPS.

Terminal window
RP_NAME=<SERVICE_NAME> # Friendly name of the service
HOSTNAME=<DOMAIN_NAME> # Hostname of the service
ORIGIN=https://<DOMAIN_NAME> # Origin of the service

If you are using a custom Android client, make sure to update the SHA256 fingerprint.

Terminal window
ANDROID_SHA256HASH=<00:00:...> # SHA256 fingerprint of the Android client
ANDROID_PACKAGENAME=<com.example.my-wallet> # Package name of the Android client

Configuration for MongoDB

Terminal window
DB_HOST=<MONGO_DB_HOST:PORT> # Hostname of the MongoDB instance
DB_USERNAME=<MONGO_DB_USERNAME> # Username for the MongoDB instance
DB_PASSWORD=<MONGO_DB_PASSWORD> # Password for the MongoDB instance
DB_NAME=<MONGO_DB_NAME> # Database name
DB_ATLAS=false # Set to true if using MongoDB Atlas

Configuration for Redis

Terminal window
REDIS_HOST=<REDIS_HOST> # Hostname of the Redis instance
REDIS_PORT=<REDIS_PORT> # Port for the Redis instance
REDIS_USERNAME=<REDIS_USERNAME> # Username for the Redis instance
REDIS_PASSWORD= # Password for the Redis instance
