Docker Images

A pre-built Docker image is available in these Docker Hub repository (maintained by the LinuxServer team):

LinuxServer - x64, armhf, aarch64

This image has the option to pull in an extra docker manifest layer to include the Calibre ebook-convert binary. Just include the environmental variable DOCKER_MODS=linuxserver/calibre-web:calibre in your docker run/docker compose file. (x64 only)

If you do not need this functionality then this can be omitted, keeping the image as lightweight as possible.

Both the Calibre-Web and Calibre-Mod images are rebuilt automatically on new releases of Calibre-Web and Calibre respectively, and on updates to any included base image packages on a weekly basis if required.
