alphawong / html2pdf

A simple docker image for easily convert html to PDF based on [wkhtmltopdf] for invoice issuing

Objective

Offer an API to convert html to pdf via POST method

How

It wraps wkhtmltopdf for the html convert to pdf. The reason we do not use weasyprint is that weasyprint do not offer a suitable converted result. However, wkhtmltopdf always return a suitable result. Also, chrome headless mode do not have the feature that we needed such as footer and header.

Run via docker

docker run -it --rm -p 8000:80 registry.gitlab.com/alphawong/html2pdf

Run

./reload.sh
