Several named volumes have been created in docker-compose. How to create these in Kubernetes?

How to transform the following named volume example defined in docker-compose to kubernetes format

k8s have documentation page about volumes and their types https://kubernetes.io/docs/concepts/storage/volumes/

So in short you need to define spec.volumes and spec.containers[].volumeMounts like:

apiVersion: v1
kind: Pod
metadata:
  name: test-pd
spec:
  containers:
  - image: gcr.io/google_containers/test-webserver

    volumeMounts:
    - mountPath: /cache
      name: cache-volume
  volumes:
  - name: cache-volume
    emptyDir: {}
