This is my Dockerfile

RUN apt-get install nginx -y
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

Please help me build an image. Please post the dockerfile commands what i should mention.

Answer 1

DockerFile:

FROM ubuntu:latest
MAINTAINER My Name "[email protected]"
RUN apt-get update && apt-get upgrade -y
RUN apt-get install nginx -y
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

This is the command using which you can build your docker-image.

docker build - < Dockerfile

Answer 2

Name of your file should be Dockerfile instead of any other naming like dockerfile, dockerFile, etc.
