how to communicate with daemonset pod from another pod in the same node?

i want a daemonset-redis where every node will have it's own caching and each deployment pod will communicate with it's local daemonset-redis how to achieve it? how to reference daemonset pod in the same node from within docker-container?

UPDATE: i rather not use service option and make sure each pod access its local daemonset

apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: redislocal
spec:
  selector:
    matchLabels:
      name: redislocal
  template:
    metadata:
      labels:
        name: redislocal
    spec:
      hostNetwork: true
      containers:
      - name: redislocal
        image: redis:5.0.5-alpine
        ports:
        - containerPort: 6379
          hostPort: 6379

Solution

There is a way of not using a service.

You can Expose Pod Information to Containers Through Environment Variables.

And you can use status.hostIP to know the ip address of node where pod is running. This was introduced in Kubernetes 1.7 link

You can add that to your pod or deployment yaml:

env:
- name: HOST_IP
  valueFrom:
    fieldRef:
      fieldPath: status.hostIP

It will set an variable HOST_IP which will have a value of node ip on which the pod is running, then you can use it to connect to a local DeamonSet.
