In my Dockerfile I have the following 'COPY" statement:
# Copy app code COPY /srv/visitor /srv/visitor
It should go without saying that in my host system, under the "/srv/visitor" directory, there is indeed my source code:
[root@V12 visitor]# ls /srv/visitor/ Dockerfile package.json visitor.js
Now, when I try to build an image using this Dockerfile it hangs at the step when the "COPY" is supposed to happen:
Step 10 : COPY /srv/visitor /srv/visitor INFO srv/visitor: no such file or directory
It says that there is no such directory, but there clearly is.
It has been pointed to me that I was mistaken, in the way I understood build context. The suggestion amounted to changing the "COPY" statement to this:
COPY . /srv/visitor
The problem is that I had it this way, and the build process halted at the very next step:
RUN npm install
It said something along the lines of "no package.json file found", when there clearly is one.
I tried running it with this change in the Dockerfile:
COPY source /srv/visitor/
It halted when trying to run npm:
Step 12 : RUN npm install ---> Running in ae5e2a993e11 npm ERR! install Couldn't read dependencies npm ERR!

So, has the copy been performed? If yes, why is npm unable to find package.json?
