What is the difference between using k8s to manage docker and using docker alone in normal development steps?

  docker, question

For example, the previous development was only deployed on docker, and no management tools such as k8s were installed. Will there be any difference in the development steps? If K8s is installed, will it affect some previously deployed services? ?

There will not be much difference in the development steps, only a yaml file needs to be generated manually or automatically after the mirror image is built. The latter problem will not theoretically have a functional impact on the service, of course the resource occupation is certain.
