How to Install Posteria on Your Synology NAS

Posteria is a web-based media poster management app designed to organize and store custom posters for movies, TV shows, seasons, and collections. It features a clean, modern interface and integrates with Plex Media Server, allowing users to import posters directly and sync customized artwork back securely using a Plex authentication token. Built as a responsive Progressive Web App (PWA), Posteria works seamlessly across devices and supports automatic poster fetching from sources like The Movie Database (TMDB), The TV Database (TVDB), and FanarTV. In this step by step guide I will show you how to install Posteria on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Posteria v1.5.3 release.

🟢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.
