@janetkuo did you test with compose v1 which doesn't include volume name ?

Yes, I tested against docker-gitlab.yml, and an example output is:

$ kompose convert -f docker-gitlab.yml -y 
file "postgresql-svc.yaml" created
file "redisio-svc.yaml" created
file "gitlab-svc.yaml" created
file "redisio-deployment.yaml" created
file "gitlab-deployment.yaml" created
file "postgresql-deployment.yaml" created

$ cat redisio-deployment.yaml 
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    service: redisio
  name: redisio
spec:
  replicas: 1
  selector:
    matchLabels:
      service: redisio
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        service: redisio
    spec:
      containers:
      - image: sameersbn/redis
        name: redisio
        ports:
        - containerPort: 6379
          protocol: TCP
        resources: {}
        volumeMounts:
        - mountPath: /var/lib/redis
          name: ls6k1hh2gdnyxxvi7hvs
      restartPolicy: Always
      volumes:
      - hostPath:
          path: /srv/docker/gitlab/redis
        name: ls6k1hh2gdnyxxvi7hvs
status: {}

I didn't assume that volume name is specified (even for v2, volume name isn't required), and if it's not, just use the current random volume name.

Just rebased.

I added a unit test, tested locally with go test -tags experimental (how do we enable testing in travis?)
