Docker how to build an image with dockerfile in ngnix?

Question

I want to build an image and I have already build my Dockerfile.I already have the container,but the image is difficult for me to buiold it.this is code for Dockerfile:

FROM nginx:alpine
COPY . /usr/share/nginx/html

But the problem is, I tried to run it on my terminal (I am using MacBook Terminal) with this command.This code what I wrote in the terminal:

Build an image from a Dockerfile
tiadem_tatie@SIT-SMBP1606 ~ % docker run -p 80:80 countly_new

The document Dockerfile is in my downloads folder. Can I have there command and if it is possible, I need help to how to build a mongoDB and Backend.Then I want to connect both together. Thanky you

Why would you keep your project files in Downloads folder? It sounds like a horrible idea.

Still, assuming that both your Dockerfile and your website files are located there run the following command to build the image:

docker build -t countly_new:latest ~/Downloads
