I recently ran across gravity-sync and really like the premise. I run my piholes in containers on 2 different docker engine hosts.
However, I am not fond of the idea of installing any applications on the host other than the base system binaries required to run my containers.

I looked at different options and building containers to isolate gravity-sync in its own docker container (along with requisite sshd) in order to limit ssh exposure between processes. However, looking through the gravity-sync script I am noticing that GS needs to access the individual pihole processes to trigger refreshes/reloads/etc.

Is there any way that I can run GS in an isolated container, or is that something that is completely out-of-scope and too difficult to manage?
