从本地 Dockerfile 构建 Docker 挂起（Windows 10）

Question

I'm brand new to Docker, and I'm trying to run a Dockerfile on my Windows 10 machine, but it's hanging initially and not doing anything.

My Dockerfile:

FROM busybox:latest
CMD ["date"]

My command from docker

$ docker build -f /projects/docker_test .

Other things of note:

Docker Toolbox installed on Windows 10 Home edition

Environmental variable:

HOME = G:\projects\

Dockerfile location:

G:\projects\docker_test\Dockerfile 

File created initially with Notepad.

EDIT: I am able to load other docker containers just fine. Docker simply hangs when I try to access a local Dockerfile.

Answer 1

对我.dockerignore是添加一个.dockerignore文件并在那里添加不属于构建图像的文件夹（在我的例子中是/node_modules ）。

Answer 2

The -f option is used to specify the path to the Dockerfile.

Try with:

docker build -t docker_test -f /projects/docker_test/Dockerfile /projects/docker_test

or:

cd G:\projects\docker_test\
docker build -t docker_test .

Answer 3

The reason for this is If we have any other folders or nested folders and files present in the same directory. Then this is happening and resolution is either to add .dockerignorefile or just move it to a folder and then move to that folder from command prompt and then execute docker build command.
