I'm setting up a kubernetes deployment with an image that will execute docker commands (docker ps etc.).

My yaml looks as the following:

kind: Deployment
apiVersion: apps/v1
metadata:
  name: discovery
  namespace: kube-system
  labels:
    discovery-app: kubernetes-discovery
spec:
  selector:
    matchLabels:
      discovery-app: kubernetes-discovery
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        discovery-app: kubernetes-discovery
    spec:
      containers:
      - image: docker:dind
        name: discover
        ports:
        - containerPort: 8080
          name: my-awesome-port
      imagePullSecrets:
        - name: regcred3
      volumes:
      - name: some-volume
        emptyDir: {}
      serviceAccountName: kubernetes-discovery

Normally I will run a docker container as following:

docker run -v /var/run/docker.sock:/var/run/docker.sock docker:dind

Now, kuberntes yaml supports commands and args but for some reason does not support options.

What is the right thing to do?

Perhaps I should configure a volume, but then, is it volumeMount or just a volume?

I am new with kubernetes so it is important for me to do it the right way.

Thank you
