I have a simple microservice setup running in a minikube cluster. It is inspired by this example. My setup includes a simple router microservice that contains a golang webserver. What I want to test now is the loadbalancing when there is more then one pod. But there seems to be no load-balancing whatsoever.

The kubernetes file for the microservices looks like this:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: router
  labels:
    app: router
    tier: router
spec:
  replicas: 2
  strategy: {}
  template:
    metadata:
      labels:
        app: router
        tier: router
    spec:
      containers:
      - image: {myregistry}/router
        name: router
        resources: {}
        ports:
          - name: target-port
            containerPort: 8082
        env:
          - name: PORT
            value: "8082"
status: {}
---
apiVersion: v1
kind: Service
metadata:
  name: router
  labels:
    app: router
    tier: router
spec:
  type: LoadBalancer
  selector:
    app: router
    tier: router
  ports:
  - port: 8082
    name: http
    targetPort: target-port

The skaffold config looks like this:

apiVersion: skaffold/v1beta2
kind: Config
build:
  artifacts:
  - image: {myregistry}/router
    context: src/router/bin
  tagPolicy:
    gitCommit: {}
  local:
    push: false
deploy:
  kubectl:
    manifests:
    - ./kubernetes/**.yaml

Kubernetes correctly deploys two pods. The output of kubectl get pods looks like this:

NAME                           READY   STATUS    RESTARTS   AGE
router-7f75f6f9df-c8mgp        1/1     Running   0          14m
router-7f75f6f9df-k248m        1/1     Running   0          14m

From the skaffold dev log output I can see that every request is routed to the router-7f75f6f9df-c8mgp pod. Even with different browsers all requests end up at the exact same pod.

When I delete this pod there is even a slight downtime of the router microservice even though there is another pod running.

What could be the problem of this behavior?
