When xds-server is started as a systemd service, default environment variables are set into

/etc/default/xds-serverfile.

xds-server configuration is also driven by a JSON config file (config.json), and default JSON config is

/etc/xds-server/config.json.

Note:youcanuseyourownJSONconfigbysettingsAPP_CONFIGvariableof/etc/default/xds-
