Question

我停止了Docker容器。然后我在linux中重新启动服务（服务docker restart）

之后，我的容器丢失了。我输入了docker ps -a，但找不到我的垃圾容器。

我也可以找到容器目录和卷文件夹。还有检查结果中的每个文件夹。但输入docker ps -a

时看不到

如何恢复它？

这是我的docker检查结果，当容器存在时。

Answer 1

在我们学习的文档中，这是docker服务的默认行为：

默认情况下，当Docker守护程序终止时，它将关闭正在运行的容器。从Docker Engine 1.12开始，您可以配置守护程序，以便在守护程序不可用时容器仍在运行。此功能称为实时还原。实时还原选项有助于减少由于守护程序崩溃，计划内的中断或升级而导致的容器停机时间。

Here，您可以了解在发生服务超时时如何保持容器的生命。

here可以为重新配置docker服务时仍处于活动状态的容器进行配置。

尽管实时恢复和重新启动策略看起来很相似，但它们具有不同的用途：

重新启动策略与dockerd命令的--live-restore标志不同。使用--live-restore可以使您的容器在Docker升级期间保持运行，尽管网络和用户输入被中断。

重启服务后Docker容器消失
