I'm using paperless-ngx docker, I need to install a few more pip packages for a post processing script I'm creating (Using ChatGPT to get me the costs in bills and receipts and add it as a field to each document).

I tried to write - 

-it paperless-ngx sh -c 'pip install PyPDF2 openai'

In the Extra Parameters field, and it failed so badly, it messed up the installation, I had to reinstall the docker... (and re-set all the parameters and variables, a big headache).

What should be the trick to do that? What am I missing?

 

Replying to myself here for a minute, I made some progress but still no success - 

I wrote - 

--entrypoint /usr/src/paperless/scripts/startup.sh in the "Extra Parameters"

And startup.sh is 

#!/bin/sh
pip install PyPDF2 openai
/usr/sbin/docker-entrypoint.sh

 

But /usr/sbin/docker-entrypoint.sh is probably not the right entrypoint, or I'm missing something obvious here, because the docker doesn't load. Any assistance will be highly appreciated.

I get the error:

/usr/sbin/docker-entrypoint.sh: line 162: $1: unbound variable

 

I then modified startup.sh to be:

#!/bin/sh
pip install PyPDF2 openai
/usr/sbin/docker-entrypoint.sh "$@"

And now I don't see any issues in the log, it just stops and doesn't continue.

 

The log now ends with:

For anyone looking to do the same, I solved it. 

startup.sh needs to be:

#!/bin/sh

# Install necessary Python packages
pip install PyPDF2 openai

# Default command if none is provided
if [ -z "$1" ]; then
  set -- "/usr/local/bin/paperless_cmd.sh"
fi

# Execute the original entry point script with provided arguments
exec /sbin/docker-entrypoint.sh "$@"

and "Extra Parameters" is:

--entrypoint /usr/src/paperless/scripts/startup.sh

Important to not forget "chmod +x startup.sh" and the proper path allocation in unraid, in my case from "/mnt/cache/appdata/paperless-ngx/scripts/" to "/usr/src/paperless/scripts"
