VULTR DDNS with PHP

Utilize Vultr DNS and Vultr API to create yourself a free DDNS!

You can use this single file (along with a config file) to easily use Vultr API and create yourself a DDNS solution for your homelab.

How does it work?

1. Have an account on Vultr
2. Obtain an API key from https://my.vultr.com/settings/#settingsapi
3. Create a DNS domain in Products > Network > DNS
4. Create A records (i.e. local.mydomain.com, dev.mydomain.com, mymediaserver.mydomain.com, etc)
5. Clone this repo in your homelab
6. Clone the vultrdns.config.json.sample file and rename it into vultrdns.config.json file
7. Update the config with your settings. dynamic_records section should consist of only A record names. I.e. ["local", "dev", "myymediaserver"]
8. Create a cron job with a reasonable interval as follows: cd /path/to/repo/directory/ && php VultrDNS.php (I used every 30 minutes throughout everyday so it will check for changes and update the record accordingly)

By the way, big shout outs to @andyjsmith for inspiring me into making this project with his awesome https://github.com/andyjsmith/Vultr-Dynamic-DNS repo!

I know the script is very very crude. So all contributions are welcome :) All hands on deck!
