Question

我试图在我的vServer上运行/安装docker并且即使可能也找不到信息..我尝试过CentOS（6＆amp; 7），Ubuntu，Debian和fedora现在，我只是无法让docker守护进程运行。

在每个系统上都有一个不同的问题，我浪费时间和时间来解决它们。

这篇文章表明它可能在使用旧内核的vServer上根本不起作用，就像我的情况一样..

是否有人真的设法在vServer上使用docker，如果有，你的主机系统有哪个内核？

如果这很重要，我在https://www.netcix.de有一台便宜的服务器。

Answer 1

安装页面有一个“Check kernel dependencies”部分，它清楚地提到了Docker运行所需的最低内核级别：

守护进程模式下的Docker具有特定的内核要求。有关详细信息，请在 Installation 中查看您的发布内容。

3.10 Linux内核是Docker的最低要求。早于3.10的内核缺少运行Docker容器所需的一些功能。众所周知，这些旧版本存在导致数据丢失的错误，并且在某些情况下经常会出现恐慌。

建议使用3.10（或更新的维护版本）Linux内核的最新次要版本（3.x.y）。使用最新的次要版本保持内核更新将确保关键的内核错误得到修复

因此，如果您的发行版内核太旧，或者某些其他需求未得到遵守（如Installation中所列），则可以解释为什么docker守护程序失败。

在虚拟服务器上运行docker-可能与否？
