Synology Install Changedetection With Portainer

Synology Install Changedetection With Portainer

My previous guide for Changedetection involved the use of Task Scheduler. Today I’m offering a recommended and excellent alternative for installing the latest Changedetection version via Portainer. Changedetection is a self-hosted change monitoring of web pages. Know when web pages change! Stay on top of new information! Live your data-life pro-actively instead of re-actively, do not rely on manipulative social media for consuming important information. Know when Government departments update (changes are often only on their websites) – Local government news (changes are often only on their websites) – New software releases, security advisories when you’re not on their mailing list – Festivals with changes – Real-estate listing changes. In this step by step guide I will show you how to install Changedetection on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Changedetection 0.45.13 release.
