Docker在当前目录中添加每个文件 [英] Docker Add every file in current directory

问题描述

我有一个简单的Web应用程序，希望将其放置在Docker容器中。角度应用程序位于 frontend / 文件夹中，该文件夹与 application / 文件夹一起。

I have a simple web application that I would like to place in a docker container. The angular application exists in the frontend/ folder, which is withing the application/ folder.

当Dockerfile位于 application / 文件夹中时，内容如下：

When the Dockerfile is in the application/ folder and reads as follows:

FROM node
ADD frontend/ frontend/
RUN (cd frontend/; npm install;)
CMD (cd frontend/; npm start;)

一切正常。

但是，当我将Dockerfile移到 frontend / 文件夹并将其更改为

However, when I move the Dockerfile into the frontend/ folder and change it to read

FROM node
ADD . frontend/
RUN (cd frontend/; npm install;)
CMD (cd frontend/; npm start;)

没有文件被复制并且项目无法运行。

no files are copied and the project does not run.

如何将当前目录中的每个文件和文件夹递归添加到我的文件中

How can I add every file and folder recursively in the current directory to my docker image?

推荐答案

最终工作的Dockerfile是

The Dockerfile that ended up working was

FROM node
ADD . / frontend/
RUN (cd frontend/; npm install;)
CMD (cd frontend/; npm start;)

向@Matt喊叫，以使领先。 / ./，但是我认为唯一不起作用的原因是由于某种原因，我的应用程序仅在目录内而不是在 root目录中时才运行。这可能与@VonC观察到的节点图像没有WORKDIR有关。

Shoutout to @Matt for the lead on . / ./, but I think the only reason that didn't work was because for some reason my application will only run when it is inside a directory, not in the 'root'. This might have something to do with @VonC's observation that the node image doesn't have a WORKDIR.
