Configuration

Location

You have to provide the location of the config file by setting the environment variable CORE_CONFIGFILE to path to the config file. Example:

export CORE_CONFIGFILE=./config/config.json

The config file is written in JSON format.

If the config file doesn't exist yet, it will be created and its fields will be filled with their default values.

If the config file is partially complete or of an older version, it will be upgraded and the missing fields will be filled with their default values.

If you don't provide the CORE_CONFIGFILE environment variable, the default config values will be used and the configuration will not be persisted to the disk.

As of version 16.12.0:

If no path is given in the environment variable CORE_CONFIGFILE, different standard locations will be probed:

• os.UserConfigDir() + /datarhei-core/config.js

• os.UserHomeDir() + /.config/datarhei-core/config.js

• ./config/config.js

If the config.js doesn't exist in any of these locations, it will be assumed at ./config/config.js

A minimal valid config file must contain at least the config version:

{
    "version": 3
}

Configuration

Configuration values can be changed by either editing the config file directly, or via the JSON API (API for short) or via environment variables (ENV for short). All environment variables have the prefix CORE_ followed by the JSON names in uppercase. Example:

JSON

{
   "version": 3,
   "id": "1",
   "name": "super-core-1337",
   "address": ":8080",
   "log": {
      "level": "warn"
   }
}

ENV

CORE_ID=1
CORE_NAME=super-core-1337
CORE_ADDRESS=:8080
CORE_LOG_LEVEL=warn

Following, every field of the configuration file will be described in detail:

id (string)

ID of the Core. If not set, a UUIDv4 will be generated. Default: unset

name (string)

Human-readable name of the Core. If not set a custom name will be generated. Default: unset

address (string)

HTTP listening address. Default: :8080

The default :8080 will listen on all interfaces on port 8080. To use a specific interface, write additionally it's IP, e.g. 127.0.0.1:8080 to only listen on the loopback interface.
