Heya, @nullx8
You can use cloud-init to inject a file into your Droplets at deployment that automatically sets up things like new users, firewall rules, app installations, and SSH keys. DigitalOcean’s User Data feature leverages cloud-init so you can deploy and automate the set up of several Droplets simultaneously. Learning to use cloud-init can save you a lot of set up time when deploying new Droplets.

There are a few ways to do it. You can use rc.local file or Cloud init to do it. You can also use crontab for this like below,
Create the script,
Paste your commands,
Make it executable
And then add following to your crontab,
