To access the DigitalOcean Control Panel and create a Droplet, you need a DigitalOcean account. You can create one from the DigitalOcean new account registration page if you don’t already have one.
After you log in to the control panel, click the green Create button in the top right to open the create menu.
In the create menu, click Droplets to open the Droplet create page. If you don’t have any Droplets, the Resources tab displays a large, blue Get Started with a Droplet button, which takes you to the same Droplet create page.
The Droplet create page is where you choose your Droplet’s configuration, like its operating system, how much memory it has, and which features (like backups or monitoring) to enable. The most popular defaults are pre-selected, so you can scroll to the bottom of the page and create a Droplet immediately, or you can customize any of the options in each section.
Once you create the Droplet, you should be able to connect with your SSH key. If you are not sure how to use an SSH key or how to add it, check this Documentation before creating the Droplet:
Once you have the droplet created and your SSH key added just SSH to the droplet’s IP address with user root.
