Docker compose issue while building python image, access denied or repository does not exist


I am trying to troubleshoot a tutorial on udemy on Windows 10 but why my compose file is failing to run. I tried relogging into Docker and I am able to run Docker build python:3.9-slim-bullseye successfully. Does anyone here see my issue and help me understand what is happening?

I think my issue with with the line:

apt-get update && apt-get install --no-install-recommends -y \
    build-essential \
    libpq-dev

The tutorial's original code is here on his github but most of my code is a straight copy from him. Here is a link to the repo I have of what was covered so far.

Solution

  • Looks like there's a typo on the line where you're assigning the build stage name.

    FROM python as pthyon-build-stage
    

    Change this to:

    FROM python as python-build-stage
    

    and the build stage should be named as expected for later stages.
