Hierarchy for Docker Files / "docker-compose up" issue — Question re: Chapter 2 of Django for Professionals

[Stephanie Goulet]

Hi all, any help would be appreciated:

Question:

1. In the below screenshot of VSC, are the last six files all in the right hierarchical place? In other words, should any of those be within either the "django_project" or "pages" folders? If so, which files should go in which level folder?
   
   

Context:

• I'm new to this 
• To learn, I went through the book Django for Beginners and am now working through Django for Professionals
• I'm on page 29 of Chapter 2: Docker Hello, World! in the Django for Professionals PDF
• It seems like I successfully did the "docker build ." command, but I'm running into trouble with the "docker-compose up" command. It's giving some traceback errors and a line that says "ModuleNotFoundError: No module named 'django_project'" which is why I suspect that I may have saved some of the files in the wrong place (maybe all of them belong in the 'django_project' folder?).

Thank you in advance!

Best,

Stephanie

hi Stephanie,

Can you post the screenshot of your dockerfile?

[Francisco Valadares]

  Hello Stephanie,

All the last six files can stay where they are (no problem). Observer if the commands in the Dockerfile file are copying the module(django_project) into the image. After you start the containner(docker-compose up) you could acess it with "docker exec -it <name container> sh".

How is your dockerfile and your .dockerignore?

Thanks so much, Francisco. I'm doing something wrong that makes the "docker-compose up" not work to begin with. More detail, including the traceback text below:

Dockerfile & .dockerignore match the text in Ch 2 of the book Django for Professionals; here they are just in case that's helpful:

Hi Stephanie,

It may be that the error is related to the dependencies that your project needs.

Looking at your dockerfile I see that you are not loading the dependencies inside the WORKDIR /code2

Example:
...
WORKDIR /code2
COPY requirements.txt /code2/
RUN pip install -r requirements.txt
COPY .  /code2/

....

[Stephanie Goulet]

Isn't that the same as what's already listed under the "# Install dependencies" and "# Copy project" notes in the Dockerfile?

I was looking online and it seems like this error is typically for when Django isn't installed, but I checked that it is installed in the .venv for this project, so I'm still not sure why it's happening.

Any other thoughts on this? I feel like I could be missing something obvious.

Thanks again all!

[Abdul Qoyyuum Haji Abdul Kadir]

Can you also share your docker-compose.yml file as well? It seems to be calling your django_project folder but can't seem to find it, even though the Dockerfile clearly shows that its copied.

I didn’t purchase anything, but if anyone has any other insight into this I’d be grateful. 

If not, I think I’m just going to try to start over and hope for the best. I just wish I understood where I’m going wrong. 

Thanks again,
