    Description

      We are currently using this Docker image https://hub.docker.com/r/zenika/alpine-chrome to run headless Chrome on the server-side for PDF export. This image has a couple of problems:

      • it provides an old version of Chrome, 124, versus the current 144 version
        • using a 2-years old Chrome version poses a security threat
        • recent versions of Chrome have added support for:
          • generating PDF outline (bookmarks) XWIKI-23380
          • generating tagged PDFs that are accessible (properly read by a screen reader) XWIKI-19560
        • I haven't checked, but recent versions of Chrome should be faster as well
      • even though the provided Chrome version is old, the image seems to be updated often, by reusing the same tag. Which means that, even if the image version is fixed on our side, the behavior could be different depending on which iteration of the same version was cached locally... See XWIKI-23703 for the surprise I recently had.

      Based on this I think we should look for an alternative. This one https://hub.docker.com/r/femtopixel/google-chrome-headless seems to be a good option.
