docker - docker 现在还不能在 Strato 托管的虚拟服务器上运行吗？

Question

去年冬天，我尝试使用其 docker 镜像运行 ShareLaTex。那时，让 docker 在我的虚拟 Ubuntu 14.04 服务器上运行，整个事情已经失败了。所以今天我决定再试一次。虚拟服务器已启动并运行全新的 Ubuntu 14.04。

关注installation instructions后直到执行为止

docker images

docker run

或

docker run hello-world

我将返回此行:

无法连接到 Docker 守护程序。 docker daemon 是否在此主机上运行？

所以回到过去，讨论得出的结论是内核版本不合适，因为内核仅限于提供 Starto。所以这是内核版本:

3.13.0-042stab111.12

那是旧的 discussion .

Answer 1

似乎 Strato v-servers 仍然不支持 docker。运行 docker daemon 失败:

INFO[0000] API listen on /var/run/docker.sock

不管安装的是哪个内核，它都会启动:

Linux h2267479.stratoserver.net 3.13.0-042stab111.12 #1 SMP Thu Sep 17 11:38:20 MSK 2015 x86_64 x86_64 x86_64 GNU/Linux

Strato 未将上述错误消息中提到的内核模块列为 supported kernel modules for virtual servers .

如果你需要 docker，你应该切换你的主机。
