In the following article, I would like to introduce Kubernetes, aka something like a Kubernetes 101, for me to learn and for others to get a better understanding of K8n.
Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available. (kubernetes.io)
