Deploying your first pod

To deploy our first pod, we will define a Kubernetes Deployment configuration file. This file will declare the deployment strategy (spec.strategy), how many pods we want to have at any given moment (spec.replicas), the volumes that will be provided to the pod (spec.template.spec.volumes), and the recipe that should be used to spin up the pod containers (spec.template.spec.containers):
