在虛擬服務器上運行docker-可能與否？

Question

我試圖運行/在我的vServer的安裝碼頭工人，如果它甚至有可能無法找到的信息。我試過的CentOS（6 & 7），Ubuntu的，Debian和Fedora的現在，我只是不能讓docker守護進程運行。

在每一個系統有一個不同的問題，我在浪費時間和時間上不解決他們..

這篇文章表明，它可能無法在vServer的在所有的工作老的內核，就像我的情況..

有沒有人真的可以用在vServer的，如果是泊塢窗，其內核是您的主機系統有哪些？

我有一個便宜的服務器在https://www.netcix.de如果這是非常重要的。

Answer 1

安裝頁面有一節「Check kernel dependencies」，明確提到了可以預料的最小內核級的碼頭工人運行：

碼頭工人在守護進程模式具有特定的核心要求。詳情請參閱Installation。

3.10 Linux內核是碼頭工人的最低要求。內核早於3.10缺乏運行Docker容器所需的一些功能。已知這些較舊的版本具有錯誤，這些錯誤在某些情況下會導致數據丟失和頻繁恐慌。建議在3.10（或更新版本保持）Linux內核的

最新次要版本（3.x.y）。保持內核達到與最新的次版本將確保關鍵內核錯誤得到修復

所以，如果你的發行版有一個內核太舊，或者一些其他的要求得不到尊重（如Installation上市），這可以解釋爲什麼docker守護進程失敗。
