In this complete Docker and Kubernetes tutorial Nana from Techworld With Nana and I have collaborated to teach you the fundamentals of docker and Kubernetes. There will be 2 parts. Docker tutorial and Kubernetes tutorial.

Starting with docker for beginners to all you need to know about creating docker images, running docker containers, docker volumes, container registry and docker architecture.

Then Kubernetes turorial for beginners including Kubernetes architecture, Kubernetes pods, services, config maps all the way to Kubernetes deployments.

You will learn the differences between docker vs Kubernetes allowing to start using these two technologies with confidence upon course completion
