Build

Execute ./gradlew assemble.
The resulting binary will be located in ./build/bin/releaseExecutable/.

Removing the extension from the binary and adding it to /usr/local/bin/ enables the use of ddns in the terminal.

Usage

The following command updates all A and AAAA DNS records in Porkbun for example.com and test.example.com.

ddns porkbun \ 
    --key=... \
    --secret-key=... \
    --domain=example.com \
    --subdomain= \
    --subdomain=test

Optionally, a file can be used to declare one or more configurations.
The above example can be declared as follows.

porkbun
key=...
secret-key=...
domain=example.com
subdomain=
subdomain=test

To use this config file, execute the command ddns --config=.... By default, the config file is /etc/ddns.conf.

This process can be automated using systemd or cron.
