在 Debian 上安裝 docker-ce 時出錯
我在伺服器上安裝 docker 時遇到問題：

PRETTY_NAME="Debian GNU/Linux 8 (jessie)" NAME="Debian GNU/Linux" VERSION_ID="8" VERSION="8 (jessie)" ID=debian核心：
2.6.32-042stab127.2
從Docker 的安裝文件中，所需的最低核心是 3.10，並且您正在執行 2.6.32-042stab127.2 和通常執行 3.16 的 Debian 8。
它似乎是一個 OpenVZ 核心。從它的首頁上看，它已經是一個基於容器的虛擬化。所以這意味著在容器中執行一個容器。雖然這是可能的，但也有一些限制，尤其是對於像 Docker 這樣用於執行和控制容器的應用程序。
這是使環境無法執行 Docker 的兩個原因。您應該嘗試使用更常見的虛擬化的提供商。如果您可以選擇您的核心（甚至在提供的列表中）或更改它，那應該是一個合適的選擇。當然，裸機也是一個合適的選擇。
