Configuration

See config.schema.json.

Environment variables

You may use environment variables to define any configuration option. This is not the recommended way to use configuration: it is better to modify the actual configuration file, is possible.

E.g. if you want to set the private key, you can define a variable like this:

STREAMR__BROKER__CLIENT__AUTH__PRIVATE_KEY = '0x1234'

It corresponds to this configuration file:

{
    "client": {
        "auth": {
            "privateKey": "0x1234"
        }
    },
    ...
}

All environment variable names start with STREAMR__BROKER__ and each configuration block is separated by double underscore. Blocks and properties are defined in CONSTANT_CASE instead of camelCase.

If the value is defined both in an environment variable and a configuration file, the environment variable value is used.

It is possible to define arrays by adding a numeration suffix to a block/property:

STREAMR__BROKER__CLIENT__NETWORK__TRACKERS_1__ID = '0x1234'
STREAMR__BROKER__CLIENT__NETWORK__TRACKERS_2__ID = '0x5678'
STREAMR__BROKER__AUTHENTICATION__KEYS_1 = 'foo'
STREAMR__BROKER__AUTHENTICATION__KEYS_2 = 'bar'

Note that the first item of an array has index 1 (not 0).
