Configuring DDNS-Updater for Reverse Proxy¶

Reference: https://hub.docker.com/r/qmcgaw/ddns-updater

If you have a Dynamic IP address, you will need a way to keep your Dynamic IP Address insync with your registered domain name. The DNS-Updater container supports MANY DDNS service providers, however we need to use Cloudflare as part of the Authelia zero trust framework for our multifacture authentication, so it makes sense to use Cloudflare to also host your domain and update it with DDNS-Updater. Head over to Cloudflare and register a free account: https://dash.cloudflare.com/sign-up

Once you have registered a free account with Cloudflare, you can transfer your existing domain to Cloudflare with "Domain Registration" → "Transfer Domains", or you can purchase a new domain inside Cloudflare with "Domain Registration" → "Purchase Domains".

If you don't want to pay for a domain and want to use a free DDNS domain, then check out the DDNS-Updater documenation and follow the DDNS set up for your preferred option.

Configure the DDNS-Updater by editing the "config.json" file with the details and credentials for your DDNS provider.

sudo vi FOLDER_FOR_CONFIGS/ddns-updater/config.json

{
  "settings": [
    {
      "provider": "cloudflare",
      "zone_identifier": "zone id",
      "domain": "your-domain-name.com",
      "host": "@",
      "ttl": 600,
      "token": "yourtoken",
      "ip_version": "ipv4"
    }
  ]
}

Restart the DDNS-Updater container, then check the status at: http://localhost:6500
