+The image is published with each version to Github Container Registry under [external-dns-myrasec-webhook](https://github.com/Myra-Security-GmbH/external-dns-myrasec-webhook/pkgs/container/external-dns-myrasec-webhook).

-|-----------|-------------|---------|
-| `dry-run` | Run in dry-run mode without making actual changes | `"false"` |
-| `environment` | Environment name (affects private IP handling) | `"prod"` |

 ## Troubleshooting
 
 ### Common Issues
 
 1. **Webhook not receiving requests**
+
    - Ensure the `webhook-provider-url` in the external-dns args is correct
    - Check network connectivity between containers
 
 2. **DNS records not being created**
+
    - Verify MyraSec API credentials are correct
    - Check if the domain filter is properly configured
    - Look for error messages in the webhook and external-dns logs
