Metadata Remote (mdrm) is a modern, open-source web-based metadata editor designed for managing large music collections on headless servers. It offers a clean, user-friendly interface for editing audio file metadata, featuring intelligent metadata inference and edit history memory. With bulk editing capabilities, it simplifies the process of organizing and updating metadata for extensive music libraries, making it an efficient tool for music enthusiasts and server administrators. The app can be easily installed via Docker, ensuring straightforward deployment. In this step by step guide I will show you how to install Metdata Remote on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Metadata Remote v1.1.0 release.

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

• STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it mdrm. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Now create one new folder inside the mdrm folder that you have previously created at STEP 3, and name it music. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 5

Populate your music folder with your own .mp3 or .flac files.

• STEP 6

Log into Portainer using your username and password. On the left sidebar in Portainer, click on Stacks then + Add stack. Follow the instructions in the image below.

• STEP 7

In the Name field type in mdrm. Follow the instructions in the image below.

Note: Copy Paste the code below in the Portainer Stacks Web editor.

🟢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 11

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://Synology-ip-address:8338 If everything goes right, you will see the Metadata Remote dashboard. Follow the instructions in the image below.

Enjoy Metadata Remote!
