For HTML To PDF export, I have mainly used wkhtmltopdf. Rotativa is built upon it for .net and asp.net core. It works fine but I was not able to get it working with Docker using linux containers.
Finally switched to “html-pdf” node.js package which internally uses phantom.js. I was able to get sample application running in docker. Need to explore more for its feature capabilities.
