第一个守护程序几乎以默认配置运行。我正在尝试按照https://docs.docker.com/engine/reference/commandline/dockerd/#run-multiple-daemons中的说明启动具有不同配置的第二个docker守护程序。
完整命令，以及完整的调试日志。

现在，第一个守护程序使用的默认桥docker0丢失了。因此，当我启动一个容器尝试连接到默认守护程序时，会出现此错误。
docker: Error response from daemon: failed to create endpoint romantic_allen
on network bridge: adding interface veth5b99b4e to bridge docker0 failed:
could not find bridge docker0: route ip+net: no such network interface.
我是否错过了应该存在的任何标志，该标志删除了默认守护程序的网络和网桥？
