A Clojure utility to update your GoDaddy dns A and AAAA records (for dynamic IP).
Your GoDaddy key and secret should be set in either a .lein-env file, system environmental variables, or Java system properties. Note that the Clojure environ library takes ENV_VAR -> :env-var, env.var -> :env-var, etc.
If compiling to Uberjar, you must use Java properties or system environmental variables.
GODADDY_KEY=${key} GODADDY_SECRET=${secret} java -jar update-godaddy.jar
or
java -Dgodaddy.key=key -Dgodaddy.secret=secret -jar update-godaddy.jar
lein uberjar
Resulting standalone .jar can be found in build/uberjar.
The author is an amateur programmer and sysadmin, and only knows about systemd service files from what he learned on the internet, so this might not be the best example or technically clean, but it works:
Move the .jar file to somewhere where you can remember, like usr/local/bin, and chown to root if you want, with the right permissions (755?).
Create a file in /etc/systemd/system, update-godaddy.service
[Unit]
Description=Update Godaddy DNS IP for this server.
Wants=network-online.target
After=network-online.target
[Service]
Type=simple
ExecStart=ENV_VARS=env_var java -jar /usr/local/bin/update-godaddy.jar
[Install]
WantedBy=multi-user.target
You can put the environmental variables in the service file like so:
...
[Service]
Type=simple
Environment="GODADDY_KEY=key"
Environment="GODADDY_SECRET=secret"
ExecStart=...
chmod the service file to 644.
Then run:
sudo systemctl start update-godaddy
and check status with
sudo systemctl status update-godaddy
To enable service start on system boot:
sudo systemctl enable update-godaddy
