Question

I am working with Docker, and I have created a JavaScript file that prints "Hello World." I have successfully built the docker image "hello-world". But, when I do this:

**User\user\Desktop> docker build -t hello-world .**

 => [internal] load build definition from Dockerfile  0.1s 

 => => transferring dockerfile: 31B                   0.0s

You are using the image of nginx webserver which does not have nodejs installed. A docker Image containing Nodejs would be more suitable for you. If you want to use nginx Container you have to build your webapp first and copy the build artifacts into the nginx container.
