# pihole-cloudsync
A script to help synchronize Pi-hole blocklist, blacklist, whitelist, regex, and `/etc/hosts` files across multiple Pi-holes using a Git repository.
+href="https://pi-hole.net/">Pi-hole blocklist, blacklist, whitelist, regex (and optionally `/etc/hosts` files) across multiple Pi-holes using a Git repository.
# Why pihole-cloudsync?
-I run six Pi-holes on three different networks at three different physical locations. I wanted all six Pi-holes to share the same blocklists, blacklists, whitelists, and regex files, but it was time-consuming to manually synchronize all of them (modify the local Pi-holes, VPN into the second network and modify those, then VPN into the third network and modify those). I also wanted the ability to share a common section of `/etc/hosts` between multiple Pi-holes so that the Pi-hole UI stats display the proper local hostnames instead of IP addresses.

I wanted to use Pi-hole's built-in web UI to manage only *one* set of lists on *one* Pi-hole -- and then securely synchronize an unlimited number of additional Pi-holes. I couldn't find an existing script that did exactly what I wanted... so I wrote `pihole-cloudsync`.

# How pihole-cloudsync Works
`pihole-cloudsync` allows you to designate any Pi-hole on any network to act as your "Master" or "Primary." This is the only Pi-hole whose list settings you will need to manage using Pi-hole's built-in web UI. The Primary Pi-hole then uses `pihole-cloudsync` in **Push** mode to *upload* its blocklist, blacklist, whitelist, and regex files to a private Git repository that you control (such as GitHub).
-All other Pi-holes that you wish to keep synchronized use `pihole-cloudsync` in **Pull** mode to *download* your Primary Pi-hole's blocklist, blacklist, whitelist, and regex files from your private Git repository.
+All other Secondary Pi-holes that you wish to keep synchronized use `pihole-cloudsync` in **Pull** mode to *download* your Primary Pi-hole's blocklist, blacklist, whitelist, and regex files from your private Git repository.
+
+If you enable the optional **Shared Hosts** mode (more details on that below), `pihole-cloudsync` will also scan for a specially marked section of your Primary Pi-hole's `/etc/hosts` file and push it to your private Git repository. Your Secondary Pi-holes can then pull the shared hosts data from the repo and insert it into their existing `/etc/hosts` files.
The script is designed to work with any Git repo that your Pi-holes can access, but I have only personally tested it with GitHub.

## Alternative Configuration: All Secondary (no Primary) Pi-holes
Once you've successfully pushed your Primary Pi-hole's lists to your remote Git repo, you could optionally choose to edit/manage your whitelist, blacklists, and regex files directly on your Git repo using your cloud-based Git provider's built-in editing tools. If you go this route, you'll need to re-configure what was previously your Primary Pi-hole to run in Pull mode (which will turn it into a Secondary). Do:
