(Docker) Getting the error: docker-php-source: there is no such file or directory when creating the docker file

Question

When I try to create a docker file in: https://github.com/docker-library/php/blob/3f43309a0d5a427f54dc885e0812068ee767c03e/7.1/Dockerfile

: docker build -t php_image .

I am executing the following error:

Step 14 : COPY docker-php-source /usr/local/bin/
lstat docker-php-source: no such file or directory

Can someone help me deal with something wrong?

thank

You do not have the proper docker build context.

Just clone for the repo to have all the files (and its permissions):

git clone https://github.com/docker-library/php
docker build . -t php_image

But if you need to customize this image, it's easier to make your own Docker file based on the official build:

FROM php:7
RUN #your commands 
RUN ...
