How to copy file from host to container using Dockerfile

Question

I have written a Dockerfile which looks like this

FROM ubuntu:12.04

RUN apt-get update
RUN apt-get install -y wget

Now I\'m having a file

Answer 1

I got the following error using Docker 19.03.8 on CentOS 7:

COPY failed: stat /var/lib/docker/tmp/docker-builderXXXXXXX/abc.txt: no such file or directory

The solution for me was to build from Docker file with docker build . instead of docker build - < Dockerfile.
