如何将计算机中的文件添加到Docker容器中？

Question

目标：

我正在尝试将文件从我的计算机复制到以下存储库中：

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
crisbal/torch-rnn   base                90e6f8c8be88        7 months ago        1.173 GB

信息：

我检查了IMAGE ID，以便找到Container值。

$ docker inspect 90e6f8c8be88 输出：

使用从检查中获取的容器值：

docker cp comments.txt dbd5803b8c916411205323a11c005e15347b4b9496f1e32f571dbe65c43b8719:/comments.txt

输出：

  

来自守护程序的错误响应：没有这样的容器：   dbd5803b8c916411205323a11c005e15347b4b9496f1e32f571dbe65c43b8719

如何将计算机中的文件添加到Docker容器中？

Answer 1

您看到和检查的内容是图片：crisbal/torch-rnn

您需要运行该图像的容器表单才能使用docker cp。

  

docker cp实用程序会将SRC_PATH的内容复制到DEST_PATH   您可以从容器的文件系统复制到本地计算机，反之亦然，从本地文件系统复制到容器

您不会复制到该存储库中的存储库或图像中，而是复制到从该图像创建的正在运行（或已停止）的容器中。
