How to Install Doku on Your Synology NAS

How to Install Doku on Your Synology NAS

Doku is a simple, lightweight web-based application that allows you to monitor Docker disk usage in a user-friendly manner. The Doku displays the amount of disk space used by the Docker daemon, splits by images, containers, volumes, and builder cache. Doku is a great alternative to Glances. In this step by step guide I will show you how to install Doku on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest Doku v0.0.16 release.
