// Docker secret files
const dockerEnv = new DockerSecretsConfigLoader({fileLowerCase: true}).getLoader;
// settings json file (i.e. modified on pipeline or agent)

const urlParser = new UrlParser({urlSanitize: true}); // urlSanitize hides credentials from logs

// lookup from: env => JSON file "settings.json" => Docker "/run/secrets/database_uri"
const databaseUrl: URL = await getConfigVariable('DATABASE_URI', [env(), fileEnv(), dockerEnv()], urlParser, undefined, {showValue: true});

// example override key: env => JSON file "settings.json" => Docker "/run/secrets/xxyyzz-database"

// lookup from: env => JSON file "settings.json" with key MONGODB => Docker "/run/secrets/database_uri"
const databaseUrl: URL = await getConfigVariable('DATABASE_URI', [env(), fileEnv('MONGODB'), dockerEnv()], urlParser, undefined, {showValue: true});
