Sorry, chown not chmod. And yes, in this section.

BUILD PIEFED

export DOCKER_BUILDKIT=1 sudo docker compose up --build

Wait until text in terminal stops scrolling. Ignore the configuration check errors at this point.
If you see many permission-related errors, try repeating the previous step **(with the chown command using 1000 instead of your username)**
Test external access from browser (On port 8030). Watch for movement in terminal window. Browser will show "Internal Server Error" message. Proceed to initialize database to address this error message.

I am getting my instructions from the official piefed codeberg repo for installing docker. https://codeberg.org/rimu/pyfedi/src/branch/main/INSTALL-docker.md. I cloned the repo in my ~/pyfedi directory, and ran the script in it as well. My issue is that I am not sure what chmod 1000 command to run to remove the docker build errors of permission denied.
