I simply have a cron job that regularly checks if my public IP[1] differs from the domain’s A-record. If it does, it updates the record to match the public IP address using their API.
I use Porkbun’s ping endpoint to obtain my public IP. There are also alternatives such as Ipify. ↩︎
Use declarative systems and software, where the configurations files themselves are the documentation. For example, I use Guix and Podman. The entire OS is described in a Scheme file and all the services are described in a YAML file. I just need those two files to get an overview of the entire setup.
