17 mins in and I already know I found the most comprehensive video about this.

As a backend engineer, docker is most important and confusing for beginners. You made it look really easy!! Thank you!

[danswaney]

I had to change the first line in the *'Dockerfile'* to: *FROM python:3.9*

...because it was trying to use *Python 3.11* and caused a build break with *'greenlet'* and the failure when the *c_app* tries to use 'psycopg2'. Hope this helps in case someone else has the same issue I had. It all worked after citing to use *Python 3.9*.

Thank you for making this a more complete tutorial. I find it a little annoying when tutorials give you the basic information you can find on the documentation, but don't take it the step further to make it into an actual production-level app. There's a lack of truly "end-to-end" type tutorials.

You are a true saviour to junior devs trying to get through the python eco-system! You're my inspiration Zander!!

Great video! Very helpful overview and great explanations of the details. It's the most thorough (and practical) I've come across. Thanks!

[ahmedshahriarsakib]

After your Django REST API tutorial, I was looking forward to this. Thank you so much <3

[NvmThemHereIAm]

this tutorial is seriously underrated. Very useful information! Thanks

[skysaville]

Ha Ha!!! I had forgotten the env vars for pgadmin... I was going along and ran the 'up' command and it threw an error. Took me a hot second to realize I never added the environment variables for it. Funny enough... I had paused the video to troubleshoot it and work through everything, then sure enough... you hit the same error code. Kind of put a smile on my face.
Love the content!

Excellent video! Making little mistakes is absolutely fantastic. The debugging process is so valuable!

[romabalance]

Thank you! You explain really calm and sequently 🙏

[PrakashReddyK]

For you M1 mac users that get a problem when trying to migrate your db with the "docker-compose run app alembic revision --autogenerate -m "New Migration", you can try what i found to work.

The error text: (psycopg2.OperationalError) SCRAM authentication requires libpq version 10 or above

So to fix that open the Dockerfile and change python version to 3.11 = FROM python:3.11
Then after RUN pip3 install --upgrade pip ..You add the following 2 lines:
RUN apt update -y && apt install -y build-essential libpq-dev
RUN pip3 install psycopg2-binary --no-binary psycopg2-binary

Hope this help!

Absolutely brilliant tutorial. Few and far between to see architecture like this weaved together and used effectively. Well done!

[zhangmingkai]

That's great. Watched a lot of videos and that's what I needed.

[matheusc.manoel]

Got an error related to greenlet on docker-compose build.

Fixed by changing greenlet version to 2.0.a2 on requirements.txt. Not sure it broke something but the docker-compose build command worked.

[rohitgautam]

Thank you !!
This is what I was looking for :)

[AnsumanSingh]

So much to learn. Thank you for making this video.

[ChandaKumari-wzor]

Thanks a lot for this tutorial, this made my day :)

Thanks. Appreciate the video and end-to-end tutorial :-)

What could enhance this great video further, is before diving into the walk through in part 3 to set-up the main components and packages in a few slides and explain their purposes and how they interact. We get introduced to them on the fly and I found it hard to digest in one go. I guess one can rewatch this section a few times to get it but if you would make this little shortcut, I think it would bring this great video to GOLD standard :-)

Keep up the good work and valuable content!
