This image based on python:3.10.4.

Source code of API maybe coming up on GitHub soon.

You could pull image from Docker Hub or build:

git clone https://github.com/Holography7/xlsx2pdf-libre-api.git
cd xlsx2pdf-libre-api/src
docker build -t xlsx2pdf-libre-api:custom .

If you want just to run:

docker run --env HOST=0.0.0.0 --env PORT=8070 -p 8000:8070 -ti holography/xlsx2pdf-libre-api:0.1.1

Or using docker-compose:

version: "3.8"

services:
  xlsx2pdf-libre:
    image: holography/xlsx2pdf-libre-api:0.1.1
    network_mode: "host"
    ports:
     - 8000:8070
    environment:
     - HOST=0.0.0.0
     - PORT=8070

All you need it's just send bytes to API http://localhost:8000/convert_to_pdf and it response you PDF bytes.

For example, you could test it by python script request.py. Don't forget copy close to it example.xlsx.

• better handling errors
• added warnings about Java Runtime Environment. I don't know how Libre uses JRM, but in my tests not installed JRM is not critical, so i leave as is.
