Hi@akhtar,
Kubernetes is designed on top of container technology. There are some container technologies available like Docker, Podman, Crio-O. So before starting with kubernetes you should know one of the container technology in depth. It will help you to connect the concepts properly. I would like to suggest you to go through one container technology training like Docker.
If you are interested in knowing more about Kubernetes, then consider taking CKA Certification Course.
Hope this will help you.
