Calibre is a cross-platform open-source suite of e-book software by Kovid Goyal. Calibre supports organizing existing e-books into virtual libraries, displaying, editing, creating and converting e-books, as well as syncing e-books with a variety of e-readers. Editing books is supported for EPUB and AZW3 formats. In short, Calibre is a powerful and easy to use e-book manager. Users say it’s outstanding and a must-have. It’ll allow you to do nearly everything and it takes things a step beyond normal e-book software. It’s also completely free and open source, and great for both casual users and computer experts. In this step by step guide I will show you how to install Calibre on your UGREEN NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Calibre 8.7 release.

Install Portainer using my step by step guide. If you already have Portainer installed on your UGREEN NAS, skip this STEP. Attention: Make sure you have installed the latest Portainer version.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 15

Now open your browser and type in your HTTPS/SSL certificate like this https://yourname.ddns.net In my case it’s https://mariuscalibre.ddns.net If everything goes right, you will see the Calibre Login page. Type in your own CUSTOM_USER and PASSWORD that you have previously created at STEP 8, then click Sign In. Follow the instructions in the image below.
