Can you provide the installation steps that you would suggest DietPi-Software to do?

Setting up calibre
Install calibre. The newest version of calibre doesn’t seem to be available in the repos. TODO should try building newer version from source

sudo apt install calibre

Create a calibre library.

mkdir /mnt/elements/media/ebooks/
cd /mnt/elements/media/ebooks/
wget http://www.gutenberg.org/ebooks/1342.kindle.noimages -O pride.mobi
calibredb add /mnt/elements/media/ebooks/* --library-path /mnt/elements/media/ebooks/

Make sure everything works

calibre-server /mnt/elements/media/ebooks/

Try loading up http://127.0.0.1:8080

(Optional) Create a systemd service unit file to manage the server. Create file at /etc/systemd/system/calibre-server.service with the following

[Unit]
Description=calibre content server
After=network.target

[Service]
Type=simple
User=pi
Group=pi
ExecStart=/usr/bin/calibre-server "/mnt/elements/media/ebooks/"

[Install]
WantedBy=multi-user.target

Try starting up the server

systemctl enable calibre-server
systemctl start calibre-server

Nginx configuration
We want to be able to access the Calibre server via something like http://ebooks.myserver.com. Assuming DNS is already set up properly. TODO maybe a separate post on Google Domains + Nginx + LetsEncrypt

Add a new site to Nginx by creating a new file at /etc/nginx/sites-available/ebooks.myserver.com

upstream calibre_backend {
  server    127.0.0.1:8080;
  keepalive 32;
}

server {
  listen 80;
  server_name         ebooks.myserver.com;
  location / {
    proxy_pass http://calibre_backend;
  }
}

Enable site

cd /etc/nginx/sites-enabled/
ln -s ../sites-available/ebooks.myserver.com
systemctl restart nginx

Enable HTTPS
Get certs from LetsEncrypt. The app should ask you if you want to change the configuration to force HTTPS. That’ll update the Nginx config and enable HTTPS.

sudo certbot --nginx -d ebooks.myserver.com

Are you willing to help maintaining the software installation, e.g. in case of needed setup changes due to updates etc.? This is not needed, but could speed up our decision to implement it, as man power is always a topic 😉.

Many thanks for your request.

Note that a proxy and HTTPS is out of scope for the dietpi-software implementation itself. We are thinking about a general proxy guide (not only for Nginx) or even script/tool, but nothing concrete yet. HTTPS can be (with Nginx and any other webserver) enabled via dietpi-letsencrypt or manually running certbot or any other ACME client, acme.sh or such. Some may however prefer to configure the backend itself to listen on HTTPS only (rather than enabling and terminating it at a proxy), I guess Calibre supports it when providing it with a cert and key? Or is it like OctoPrint, not supporting HTTPS itself but counting on users setup a proxy for WAN access?

With the installation of Readarr this would be a great addition to fully allow for Book automation on Dietpi
