Creating a cluster with libcluster and Kubernetes

I’m having problems creating a cluster with libcluster and K8S…

The error I’m having is:

`[warning] [libcluster:k8s] unable to connect to :"foo@10.244.2.106": not part of network

These are my kubernetes configs:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: foo
spec:
  replicas: 4
  selector:
    matchLabels:
      app: foo
  template:

      labels:
        app: foo
    spec:
      serviceAccountName: foo-account
      containers:
        - name: foo
          image: full_node:latest
          args: ["--name", "foo@$(MY_POD_IP)", "--cookie", "foo-cookie"]
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 4000
          env:
            - name: MY_POD_IP
              valueFrom:
                fieldRef:
                  fieldPath: status.podIP

The libcluster config:

topologies = [
      k8s: [
        strategy: Cluster.Strategy.Kubernetes.DNS,
        config: [
          service: "foo-nodes",
          application_name: "foo"
        ]
      ]
    ]

Communication between pods are fine. Endpoints

kubectl get endpoints
NAME           ENDPOINTS                                                           AGE
foo-nodes     10.244.2.100:4369,10.244.2.101:4369,10.244.2.102:4369 + 1 more...   15m

Services

kubectl get services
NAME           TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)                         AGE
foo-nodes     ClusterIP      None            <none>        4369/TCP                        37m
foo-service   LoadBalancer   10.101.190.19   <pending>     4000:31343/TCP,4001:32461/TCP   4h53m

I followed several tutorials like this: Connecting Elixir Nodes with libcluster, locally and on Kubernetes Read the docu: Cluster.Strategy.Kubernetes.DNS — libcluster v3.5.0 I don’t know what else I can try…

Any though?
