AutoDNS

Simple golang tool to automatically update DNS records for a server.

💾 Installation

AutoDNS is built into a single binary. You can build this yourself with Golang tooling or download a prebuilt release from the Releases page.

Nightly builds are also available as artifacts on the Actions page.

🚀 Usage

AutoDNS is designed to be used in automated environments such as inside cron. As such, everything is ran using a CLI.

Available Commands:
  cf          Use CloudFlare DNS provider
  completion  Generate completion script
  help        Help about any command
  upgrade     Upgrade AutoDNS to the latest version
  version     Print version information

Flags:
  -h, --help            help for autodns
  -v, --verbose count   verbose output
  -V, --version         print version

Use "autodns [command] --help" for more information about a command.

Additionally, you can instead pass the API tokens using the AUTODNS_{provider}_TOKEN environment variables. Note that tokens passed using CLI flags take priority over environment variables. See below for a complete list.

⌛ Example with Crontab

This example assumes you have installed AutoDNS into your PATH.

# Run AutoDNS every hour and discard output
0 * * * * autodns cf --token notarealtoken --record server.jackbaron.dev > /dev/null 2>&1

📡 Providers

These are all the DNS providers currently supported by AutoDNS. If you would like to see another added, submit an issue. Instead if you're feeling generous, shoot me a PR to add a provider and I'll be eternally grateful 😄
