Books, books, books.. I’ve started a few, but finished the wonderful “DevOps” book in August. Even bought a hard copy of it.
“What is DevOps ?” is free and really short
“The Docker Book” by James Trumbull from Docker is great to learn the basics. Free as well.
Also, this one is pretty good and can be used as a reference :
“Building Microservices” is really interesting but I still have to devote time to finish it
That book on Kubernetes is really great and helpful :
“Kubernetes: Up and Running” is not available yet but the 4 first chapters are available on Preview
His author, Kelsey Hightower, is a great speaker. More about him later
