無法看到容器內的文件

我無法訪問使用docker-compose創建的容器中的內容;有人向我建議，這可能是因爲主機上的內容文件夾未正確安裝。 （注：我不知道如何驗證這個意見，所以我必須假設它是正確的。）無法看到容器內的文件

這是我的docker-compose.yml文件：

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

這裏是我的docker-compose命令的輸出：

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. Enable with --incremental 
docs_1 |  Generating... 
docs_1 |      done in 0.017 seconds. 
docs_1 | Auto-regeneration: enabled for '/usr/src/app' 
docs_1 | Configuration file: none 
docs_1 |  Server address: http://0.0.0.0:4000/ 
docs_1 | Server running... press ctrl-c to stop. 
docs_1 | [2017-07-17 20:58:02] ERROR `/favicon.ico' not found.

...這裏是結果：

C:\Users\Admin>docker exec -it 863a59969066 bash 
[email protected]:/usr/src/app# ls 
[email protected]:/usr/src/app#

正如我們所看到的，療法e在容器中沒有內容。此外，瀏覽到該網址會顯示一個空目錄：

這裏是docker container inspect結果：

C:\Users\Admin>docker inspect dockergithubio_docs_1

乍一看，這似乎不錯，但我必須承認，在缺乏知識準確地解釋細節。

我已經打開了一個問題here，但它似乎耗盡了該線程上的所有資源。

如何確定是否發生安裝錯誤，如果是的話我可以修復它？

您需要配置docker以將您的D驅動器共享到嵌入式docker VM中。沒有這一點，虛擬機在這個位置沒有任何東西，當在一個容器中將一個卷掛載到一個不存在的目錄中（在docker虛擬機中，而不是在windows機器上）時，你會得到空目錄。

見windows install steps如何分享這個驅動器：

既然你提到它，我不記得被提示來分享我的d：安裝圖像的過程中駕駛。我這麼做了，如[這裏]所示（https://i.stack.imgur.com/9U44W.png）。從那以後，我重新啓動並重新啓動了Docker服務，以及有問題的容器。還有另一種調查方法嗎？ – InteXX

啊哈！現在我們[越來越近]（https://i.stack.imgur.com/FKNgP.png）。 – InteXX

由於[其他錯誤]（https://github.com/docker/docker.github.io/issues/3808#issuecomment-315935709）在我暫時禁用了防火牆後，我不情願地選擇了[暫存文檔]（https://github.com/docker/docker.github.io#staging-the-docs）。我並不希望它能夠工作 - 在所有這些其他錯誤之後，你知道 - 但最終它[正確地解僱了]（https://github.com/docker/docker.github.io/issues/3808#issuecomment -315941143）。在你看來，驅動共享問題是否仍然適用（現在我們使用Jekyll而不是'docker-compose'）？ – InteXX
