AdGuardHome Certificate Injector

---

It's a simple ruby script that automates AdGuardHome certificate injection

Usually, you'd run this after your certbot renewal as part of your --post-hook, allowing you to automatically inject the new key and cert chain into AdGuardHome's YAML config file (example below).

Usage

Usage: ./adguardhome_certinjector.rb [options]
    -c, --config CONFIGFILE          Path to the AdGuardHome config file
    -d, --domain yoursite.com        Domain name for cert/key - LetsEncrypt (certbot) mode only
    -p, --privatekey privkey.pem     Path to your private key - Manual mode
    -i, --certchain fullchain.pem    Path to your public certificate chain - Manual mode

Examples

Use with a certbot post hook (LetsEncrypt mode)

Ideally, the chained commands would end up in a script to be passed as the single --post-hook 'command' to be run, but I've chained all three here to demonstrate the usual renewal workflow:

certbot renew --post-hook '/path/to/AdGuardHome -s stop ; /path/to/adguardhome_certinjector.rb -c /path/to/AdGuardHome.yaml -d yoursite.com ; /path/to/AdGuardHome -s start'

Use with a certificate chain and key (Manual mode)

/path/to/AdGuardHome -s stop
/path/to/adguardhome_certinjector.rb -c /path/to/AdGuardHome.yaml -p /path/to/privkey.pem -i /path/to/fullchain.pem
/path/to/AdGuardHome -s start
