Install / switch with Portainer (Stacks)

For Portainer CE/BE on any host. The cleanest path is a Stack (Portainer's name for a docker-compose file you manage in the web UI).

Your books, users, settings and Read checkmarks live in the volumes you bind into the container — not in the image — so switching keeps everything and is reversible.

Needs hardware verification: these Portainer labels and steps are docs-verified, but we do not yet have a real Portainer walkthrough or screenshots. Please use the help links below if your screen differs.

Fresh install (Stack)

  1. Stacks → Add stack.

  2. Name: calibre-web-nextgen. Build method: Web editor. Paste:

    services:
      calibre-web-nextgen:
        image: ghcr.io/new-usemame/calibre-web-nextgen:latest
        container_name: calibre-web-nextgen
        environment:
          - PUID=1000
          - PGID=1000
          - TZ=America/New_York
        volumes:
          - /path/on/host/config:/config
          - /path/on/host/library:/calibre-library
          - /path/on/host/ingest:/cwa-book-ingest
        ports:
          - 8083:8083
        restart: unless-stopped

    Replace the three /path/on/host/... values with real folders on the Docker host, and set PUID/PGID/TZ to your user and timezone.

  3. Deploy the stack. Portainer pulls the image and starts it. Open http://<host>:8083.

Switching from CWA

  • If your CWA runs as a Stack: open that stack → Editor, change the image line to ghcr.io/new-usemame/calibre-web-nextgen:latest, keep the same volume binds, then Update the stack with Re-pull image and redeploy ticked.
  • If your CWA runs as a standalone container: the tidiest switch is to recreate it as the stack above, pointing the three volumes at the same host folders CWA already uses (Containers → your CWA container → Inspect shows its current bind mounts). Stop the old container first so only one app uses the library at a time.

Updating later

  1. Stacks → your calibre-web-nextgen stack → Editor.

  2. Click Update the stack and tick Re-pull image and redeploy (older Portainer: Pull and redeploy). Portainer pulls the newest image and recreates the container with your data intact.

    (Just restarting the container does not pull a new image — you must re-pull.)


Your setup might differ. If a step doesn't match what you see on screen, or if sync / auto-ingest isn't working after you switch, we'll help you through it:

Include your platform and a screenshot of the screen you're stuck on, and we'll tell you the exact buttons to press.
