I am assuming you upload your docker image to a container registry and use it in a deployment file to run on a k8s cluster. Many people run k8s in local machine to test if things are running as expected. Creating a docker image, uploading to a CR and deploying again is time consuming. You can run something like Kind (local k8s cluster) on your local machine to test things out. It would be more time efficient.
