There is actually equivalent in Kubernetes.
Its EmptyDir volume that has medium: "memory"

https://kubernetes.io/docs/user-guide/volumes/#emptydir

My proposal is to convert tmpfs to empty dir volume.

for docker-compose.yml like this:

version: "2"

services:
    foo:
        image: busybox
        command: ["sh","-c", "mount | grep /foo; sleep 3200"]
        tmpfs: 
           - /foo

kompose should generate objects that have PodSpec like this:

      metadata:
        labels:
          service: foo
      spec:
        containers:
        - args:
          - sh
          - -c
          - mount | grep /foo; sleep 3200
          image: busybox
          name: foo
          volumeMounts:
          - mountPath: /foo
            name: foo-claim0
        restartPolicy: Always
        volumes:
        - name: foo-claim0
          emptyDir:
              - medium: "Memory"

volumeMounts and volumes are important parts.

@kadel That looks great. I think that'd be the best way to convert 'tmpfs" to Kubernetes. Even if it's not used very much in docker-compose I think it's an awesome way to convert to a kubernetes-equivilant.

I would like to work on it :)
