Docker服务主机配置启动失败

Question

我有Debian 10虚拟机。我希望能够从另一台主机连接到docker API。如果我从控制台启动docker守护程序，我可以从其他主机连接到docker

dockerd -H unix:///var/run/docker.sock -H tcp://192.168.3.157

如果我尝试像这样配置/etc/docker/daemon.json

{
  "hosts": ["unix:///var/run/docker.sock", "tcp://192.168.3.157"]
}

命令systemctl start docker失败。命令systemctl status docker具有next输出

我应该如何配置/etc/docker/daemon.json使我的守护进程正常启动？

我已经找到了答案。在这里，我已经创建了文件/etc/systemd/system/docker.service.d/override.conf Unable to start docker after configuring hosts in daemon.json content

# Disable flags to dockerd, all settings are done in /etc/docker/daemon.json
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd

然后我重新启动了服务systemctl daemon-reload; systemctl restart docker
