Dee

如果要 VNC 不要那么多权限启动 （因为现在要宿主机的权限过多）

• 可以先设置docker内访问dbus：https://georgik.rocks/how-to-start-d-bus-in-docker-container/

• Ubuntu：

  dbus-uuidgen > /var/lib/dbus/machine-id

  mkdir -p /var/run/dbus

  dbus-daemon --config-file=/usr/share/dbus-1/system.conf --print-address

• 再 vncserver 启动时 。带参数 （带上 localhost no 那一串，如果加 会启动不了） 如： /usr/bin/vncserver :1 -geometry 1366x768 -depth 24 -localhost no -fg

启动指令可以简化为：
docker run -it --rm xxx:tag /bin/bash
