I'm not able to upload the image build, it gives an error in the dockerfile, how do I do the dockerfile:

Install the container's OS.

FROM ubuntu:latest as HUGOINSTALL

Install Hugo.

RUN apt-get update
RUN apt-get install hugo

Copy the contents of the current working directory to the hugo-site

directory. The directory will be created if it doesn't exist.

COPY . /hugo-site

Use Hugo to build the static site files.

RUN hugo -v --source=/hugo-site --destination=/hugo-site/public

Install NGINX and deactivate NGINX's default index.html file.

Move the static site files to NGINX's html directory.

This directory is where the static site files will be served from by NGINX.

FROM nginx:stable-alpine
RUN mv /usr/share/nginx/html/index.html /usr/share/nginx/html/old-index.html
COPY --from=HUGOINSTALL /hugo-site/public/ /usr/share/nginx/html/

The container will listen on port 80 using the TCP protocol.

EXPOSE 80

Another question, I'm name here, I wanted to know how to put dockerfile error image
