Ep: Advanced Containers - missing step in Dockerfile prep

[gcapes]

At this point learners are supposed to edit the Dockerfile

Let’s add a new line to the Dockerfile we’ve been using so far to create a copy of sum.py

However, up to this point the only docker image we've created is in the basic directory, so the initial modification steps needed to Dockerfile haven't been made. I just copied the Dockerfile from basic and added the COPY command and it seems to run ok.

Thanks @gcapes I noticed this too when I taught it a couple weeks ago. I did the same where I copied the basic Dockerfile over. Would you like to make a PR to add this change to the lesson? If not, let me know and I'll add your suggested change.

Or alternatively, I'll update the sum/Dockerfile to have the basic as a starting point.

Given the time that has passed since creating this issue, I cant really remember the details so I'm happy for you to make the changes :)
