dns.timknowsbest.com Name does not resolve

[cdalvaro]

Describe the bug

The service doesn't start because it cannot resolve: dns.timknowsbest.com.

Looking at the code, I cannot find anywhere where that dns is set...

As a suggestion, it would be great to have versioned images to be able to point to specific versions allowing to go back if a new feature breaks the service.

To Reproduce

Steps to reproduce the behavior:

Simply start the container with the following compose.yml file:

services:
  cloudflare-ddns:
    image: ghcr.io/timothymiller/cloudflare-ddns/cloudflare-ddns:latest
    network_mode: host
    dns: 1.1.1.1
    volumes:
      - ${DATA_DIR_PATH}/config/swarm.json:/config.json:ro
    security_opt:
      - no-new-privileges:true
    environment:
      CF_DDNS_API_TOKEN: ${CF_DDNS_API_TOKEN}
      PUID: 1000
      GUID: 1000
      TZ: Europe/Madrid

Note

I'm using the image from ghcr.io to avoid Docker HUB pull limits
