我能够使用以下方式在 CoreOS 上安装 Windows 共享驱动器https://github.com/xynova/docker-cifs-build
我已经在里面创建了一个服务
$ sudo vim /etc/systemd/system/mount.service
[Unit]
Description=Mount Share service
After=network.target
[Service]
Type=oneshot
RemainAfterExit=yes
TimeoutStartSec=0
ExecStart=/opt/bin/mount.cifs //192.168.10.4/Apps/pegasus/operaII/Data/C /ccc/smb -o domain=server-apps.continental.local,username=usernam,password=password,uid=0,gid=0
[Install]
WantedBy=multi-user.target
重启后我得到了这个

我可以手动运行该服务
$ sudo systemctl start mount.service
Warning: mount.service changed on disk. Run 'systemctl daemon-reload' to reload units.

从日志中我看到网络无法访问，如果这是问题所在，我该如何在网络重新初始化后运行挂载？
答案1
在 CoreOS 上可以设置网络：
- 通过 Cloud Init
- 通过 systemd 的静态配置
https://coreos.com/os/docs/latest/network-config-with-networkd.html
在您的服务中，您可能希望更改，After=network.target因此Wants=network-online.target您的服务仅在成功配置网络后才会启动。如果通过 cloud-init 设置网络，它也应该回答相同的依赖关系。
