title
SSH Crash Course | With Some DevOps

description
In this video we will learn the fundamentals of SSH along with some basic DevOps and Linux stuff. We will start with a local Ubuntu server on my network and then create a remote Digital Ocean Droplet to work with. We will create sets of SSH keys for those as well as Github. We will even do a simple React app deployment.
