Question 4

How to create a deployment in kubernetes?

Answer 4

You need to specify the docker image name in docker-hub that you want to run in K8s node. Say you want to run nginx webserver docker image from docker-hub,

> kubectl  create  deployment  khan_depl_1  --image=nginx

deployment name is khan_depl

Normally you should specify all deployment details in a configuration yaml file, and then apply that yaml file
