Google Domains Dynamic DNS Updater
|
|
==
|
|
|
|
`googledomains_dyndns_update` is a simple tool written in Ruby to update
|
|
Dynamic DNS entries on Google Domains. More information on Dynamic DNS
|
|
pertaining to Google Domains can be found in the following support answer:
|
|
|
|
> https://support.google.com/domains/answer/6147083
|
|
|
|
Installation
|
|
--
|
|
|
|
The tool can be run by executing `googledomains_dyndns_update.rb` script from a
|
|
clone of this repository.
|
|
|
|
Configuration
|
|
--
|
|
|
|
This tool uses a configuration file, located by default in `~/.gddyndns.yaml`,
|
|
to get information on hosts to update. An alternate configuration file can be
|
|
specified with the `-f|--config_file` option. Configuration is specified in
|
|
YAML format with a template as follows:
|
|
|
|
```YAML
|
|
hosts:
|
|
- host: hostone.com
|
|
username: <google domain hostone username>
|
|
password: <google domain hostone password>
|
|
- host: hosttwo.com
|
|
username: <google domain hosttwo username>
|
|
password: <google domain hosttwo password>
|
|
- ...
|
|
```
|
|
|
|
Username and password for this file can be obtained from the Google Domains
|
|
dashboard as mentioned in the URL above.
|
|
|
|
Caching
|
|
--
|
|
|
|
To avoid frequent queries to Google Domains, store the status of latest update
|
|
to a cache file, located by default in `~/.gddyndns.cache`. Alternate location
|
|
may be provided with `-c|--cache_file` option.
|
|
|
|
Google Domains is updated only if public IP of the host has changed. An update
|
|
can, however, be forced with the `-u|--force_update` option.
|
|
|
|

|
--
|
|
|
|

|
|
|
|
```

|
