无法查看容器内的文件

Question

我无法访问使用docker-compose.yml创建的容器中的内容;有人建议我这可能是因为主机上的内容文件夹没有正确安装。 （注意：我不知道如何验证这个建议，所以我必须假设它是正确的。）

这是我的version: "2.1" services: docs: image: docs/docstage ports: - "4000:4000" volumes: - "./:/usr/src/app" 文件：

docker-compose

这是我的D:\Dev\Git\docker.github.io>docker-compose up Creating dockergithubio_docs_1 ... Creating dockergithubio_docs_1 ... done Attaching to dockergithubio_docs_1 docs_1 | Configuration file: none docs_1 | Configuration file: none docs_1 | Source: /usr/src/app docs_1 | Destination: /_site docs_1 | Incremental build: disabled.

root@863a59969066:/usr/src/app#

......这是结果：

docker container inspect

正如我们所看到的，容器中没有内容。此外，浏览到URL会显示一个空目录：

乍一看，这似乎没问题，但我必须承认缺乏准确解释细节的知识。

我已经打开了一个问题here，但似乎我已经耗尽了该主题上的所有资源。

如何确定是否发生了挂载错误，如果是，我该如何解决？

Answer 1

您需要配置docker以将D驱动器共享到嵌入式docker VM中。如果没有这个，VM在此位置没有任何内容，并且在将容器中的卷安装到不存在的目录（在docker VM内，而不是在Windows机器上）时，会得到生成的空目录。

有关如何共享此驱动器，请参阅windows install steps：
