# AdGuardHome sync

Synchronize [AdGuardHome](https://github.com/AdguardTeam/AdGuardHome) config to a replica instance.

## Current sync features

- General Settings
- Filters
- Rewrites
- Services
- Clients
- DNS Config
- DHCP Config

By default, all features are enabled. Single features can be disabled in the config.

### Setup of initial instances

New AdGuardHome replica instances can be automatically installed if enabled via the config autoSetup. During automatic
installation, the admin interface will be listening on port 3000 in runtime.

To skip automatic setup

## Install

Get from [releases](https://github.com/bakito/adguardhome-sync/releases) or install from source

```bash
go install github.com/bakito/adguardhome-sync@latest
```

## Prerequisites

Both the origin instance must be initially setup via the AdguardHome installation wizard.

## Run

```bash

export ORIGIN_URL=https://192.168.1.2:3000
export ORIGIN_USERNAME=username
export ORIGIN_PASSWORD=password
export REPLICA_URL=http://192.168.1.3
export REPLICA_USERNAME=username
export REPLICA_PASSWORD=password

# run once
adguardhome-sync run

# run as daemon
adguardhome-sync run --cron "*/10 * * * *"
```

## docker cli

```bash
docker run -d \
  --name=adguardhome-sync \
  -p 8080:8080 \
  -v /path/to/appdata/config/adguardhome-sync.yaml:/config/adguardhome-sync.yaml \
  --restart unless-stopped \
  ghcr.io/bakito/adguardhome-sync:latest
```
