Kubernetes (K8s) is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery.
Kubernetes official website
Reading the definition from Kubernetes official website it becomes clear why people often feel frustrated starting to learn this technology. Today, I prepared a list of YouTube videos that will help you to learn Kubernetes and its architecture incrementally!
This video is an introduction to Kubernetes in the form of a children's story. It was made by Deis. You can find it as an actual written story on CNCF Website.
A video from a series produced by Microsoft Azure, and led by Kubernetes co-founder Brendan Burns. You can find the complete series in this playlist.
Another great video from a series produced by a cloud provider. This time it's IBM Cloud. It is presented by Sai Vennam, IBM Technical Offering Manager. The series goes deeper than "vanilla K8s" by introducing Helm, Itsio, and other vendor solutions. You can find the rest of the series by following this link.
Yet one more series of videos by major player in a market of cloud computing. This time it is VMware Cloud. This particular video is great to learn basics about networking rules in Kubernetes stack. Presented by Nathan Ness, VMware Sr. Staff Systems Engineer. The whole series, featured other presenters, is available on the YouTube.
Sequel to The Illustrated Children's Guide to Kubernetes. The story's illustration and text is available on CNCF website.
