How to Install Gravity on Your Synology NAS

Gravity offers DNS with Ad-blocking, DHCP with automatic DNS integration, and network discovery. Built on the same code as CoreDNS and Blocky, the code is battle-tested. Additionally, Gravity’s data is fully replicated, allowing you to have a simple multi-site setup without needing to manage external databases, or worry about primary-secondary setups. DNS with built-in caching and ad/privacy blocking. The cache is replicated across all instances in a cluster, further increasing its effectiveness. Migration is also made very easy as Gravity can be set up as forwarder to forward requests to an existing DNS server, while also adding the records to its own database. In this step by step guide I will show you how to install Gravity on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Gravity v0.19.0 release.
