How to Automate Deployments Like a Pro — Adding a new Digital Ocean host to Rancher

This is the second article about automate deployments like a pro. Today, we will learn to add a new host to Rancher. Below you can find the whole series:

1. Installing Docker Rancher with SSL.
2. Adding a new Digital Ocean host to Rancher.
3. Adding a new service to our Digital Ocean Host.
4. Adding a Drone CI service.
5. Configuring Github repository with Drone CI.
6. Deploy your application.

For this tutorial, We are going to add a service server to host our services, like a web app or whatever you want.

On the Rancher, we need to go to Infrastructure > Hosts and click add host button. You will find the next view:

It is very similar to the configuration when we create a new droplet on DigitalOcean. Finally, we click on Create, and that's it! Rancher will create a new Droplet for us.

In the next article, we will create a new service inside a host.
