Updating

Updating

Calibre-Web-NextGen ships new versions regularly — often weekly. Updating means pulling the new image and recreating the container; your library, settings and reading progress live in the mounted volumes, so they're left untouched.

Update once, by hand

docker compose pull calibre-web && docker compose up -d calibre-web

(Use your own service name if it isn't calibre-web.)

Update automatically

Use Watchtower (the maintained fork). Add it alongside CWA and label the CWA service so Watchtower only ever touches this one container — your other containers are left alone:

services:
  calibre-web:
    image: ghcr.io/new-usemame/calibre-web-nextgen:latest
    labels: ["com.centurylinklabs.watchtower.enable=true"]
    # ...rest of your config

  watchtower:
    image: nickfedor/watchtower
    volumes: ["/var/run/docker.sock:/var/run/docker.sock"]
    command: --label-enable --cleanup --interval 86400   # check daily, remove old images
    restart: unless-stopped

The in-app Admin → NextGen Settings → Automatic updates panel shows these same steps, and the "Update available" banner has an Update now button that gives the right command for your setup (Compose, docker run, Unraid, Portainer/Synology).

On most NAS GUIs, a "restart" does not pull a new image — you have to re-pull. The per-platform install guides show exactly how to update on Synology, Unraid, Portainer, and TrueNAS.
