npm run production
ENTRYPOINT ["/bin/init_container.sh"]
The image run contains an installed npm. Despite this fact, the npm install return the error: /bin/sh: 1: npm: not found
How is this possible? What am I doing wrong?
Edit:
As answer to @BMitch 's comment, when I run the RUN image, in the container the node is on the PATH and I can use it. The path is /root/local/bin. I've attached all the Dockerfiles.
I have 3 docker files:

Edit 2:
It is important that if I remove the RUN npm... commands, then the whole build is a success and the result image contains the npm and I can use it (I've verified by using a container in interactive mode).
Edit 3:
Here's a lot lot simpler solution that can be tried out instantly:
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM alpine as img2
RUN cat $HOME/test.txt
The result is: cat: can't open '/root/test.txt': No such file or directory
Two issues going on here. The "php:7.2.5-apache" image won't have /root/local/bin in the path, and you did not add it to the path during your build. The npm commands will work when you login interactively likely because of some changes to the shell login scripts that setup the environment. You'll need to run these environment setup scripts before running any npm commands, and that must be done within the same RUN command. To verify for yourself, you can check your .bashrc for variables or commands run to setup the npm environment. And you can verify the environment is different by comparing the PATH value with an env command in the interactive shell and in your build, you should see two different outputs if this is your issue. When I ran part of your run image, I saw the following in the .bashrc:
export PATH=$HOME/local/bin:$PATH
So you'll want to update the line in your Dockerfile for the run image:
ENV PATH /root/local/bin:${PATH}:/home/site/wwwroot
Per your edit 3, that's an entirely different issue. You created a file in one new image, and then went back to the base image where the file doesn't exist. If you wanted to see the file in a multi-stage build, then you either need to copy it between the stages, or use the previous image as your "from".
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM alpine as img2
COPY --from=img1 /root/test.txt /root/test.txt
RUN cat $HOME/test.txt
or
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM img1 as img2
RUN cat $HOME/test.txt
