Puoi creare un deployment di pod in cui ogni pod contiene uno o più volumi. Il seguente manifest del deployment descrive un deployment di tre pod
che hanno ciascuno un volume emptyDir.
In questo esempio:
Il campo metadata: name specifica un deployment denominato
volumes-example-deployment.
La specifica Modello di pod include un campo volumes
che descrive un volume emptyDir denominato cache-volume.
La specifica del container include un campo volumeMounts: che specifica
che il volume denominato cache-volume è montato nel percorso del file /cache.
Per creare un deployment da questo file manifest, esegui questo comando:
kubectlapply-fvolumes-demo.yaml
Verifica che il deployment sia in esecuzione correttamente e che abbia il volume previsto
con questo comando:
kubectldescribepodsvolumes-example-deployment
Vengono stampate informazioni su ciascuno dei tre pod nel deployment. L'output
mostra che ogni pod ha un container, test-container, con il montaggio /cache:
Mounts:
/cache from cache-volume (rw)
L'output mostra anche che ogni pod contiene un volume denominato cache-volume:
Volumes:
cache-volume:
Type: EmptyDir (a temporary directory that shares a pod's lifetime)

For more\ndetails, see the\n[Kubernetes documentation about Volumes](https://kubernetes.io/docs/concepts/storage/volumes/).\n\nUsing Volumes with Deployments\n------------------------------\n\nYou can [create a Deployment](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/)\nof Pods where each Pod contains one or more\nVolumes. The following Deployment manifest describes a Deployment of three Pods\nthat each have an [emptyDir Volume](https://kubernetes.io/docs/concepts/storage/volumes/#emptydir).\n\nIn this example:\n\n- The `metadata: name` field specifies a Deployment named `volumes-example-deployment`.\n- The [Pod template](https://kubernetes.io/docs/concepts/workloads/pods/pod-overview/#pod-templates) specification includes a `volumes` field that describes an emptyDir volume named `cache-volume`.\n- The container specification includes a `volumeMounts:` field that specifies that the Volume named `cache-volume` is mounted at the file path `/cache`.\n- The manifest file is named `volumes-demo.yaml`.\n\n apiVersion: apps/v1\n kind: Deployment\n metadata:\n name: volumes-example-deployment\n spec:\n replicas: 3\n selector:\n matchLabels:\n app: demo\n template:\n metadata:\n labels:\n app: demo\n spec:\n containers:\n - name: test-container\n image: us-docker.pkg.dev/google-samples/containers/gke/hello-app:1.0\n volumeMounts:\n - mountPath: /cache\n name: cache-volume\n volumes:\n - name: cache-volume\n emptyDir: {}\n\nTo create a Deployment from this manifest file, run the following command: \n\n kubectl apply -f volumes-demo.yaml\n\nVerify that your Deployment is running correctly and has the expected Volume\nwith this command: \n\n kubectl describe pods volumes-example-deployment\n\nThis prints information about each of the three Pods in the Deployment. The\noutput shows that each Pod has a container, test-container, with the `/cache`\nmount: \n\n Mounts:\n /cache from cache-volume (rw)\n\nThe output also shows that each Pod contains a Volume named `cache-volume`: \n\n Volumes:\n cache-volume:\n Type: EmptyDir (a temporary directory that shares a pod's lifetime)\n\nFor more information about creating Deployments, refer to [Creating a\nDeployment](/kubernetes-engine/docs/how-to/stateless-apps#create).\n\nWhat's next\n-----------\n\n- [Learn about PersistentVolumes, PersistentVolumeClaims, and dynamic storage provisioning](/kubernetes-engine/docs/concepts/persistent-volumes).\n- [Learn about using the Compute Engine persistent disk CSI Driver](/kubernetes-engine/docs/how-to/gce-pd-csi-driver)."]]
