2.4 Using Deployment Files

To simplify the creation of pods and their related requirements, you can create a deployment file that define all of the elements that comprise the deployment. This deployment defines which images should be used to generate the containers within the pod, along with any runtime requirements, as well as Kubernetes networking and storage requirements in the form of services that should be configured and volumes that may need to be mounted.

Deployments are described in detail at:
