Kubernetes Ingress not accessible (localhost)

I am setting up a minimal Kubernetes cluster on localhost on a Linux machine (starting with hack/local-up-cluster from the checked out repo). In my deployment file I defined an ingress, which should make the services, which are deployed in the cluster, accessible from the outside. Deployment.yml:

---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: foo-service-deployment
spec:
  replicas: 2
  template:
    metadata:
      labels:
        app: foo-service
    spec:
      containers:
        - name: foo-service
          image: images/fooservice
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 7778
---
apiVersion: v1
kind: Service
metadata:
  name: foo-service-service
spec:
  ports:
    - port: 7778
  selector:
    app: foo-service
  type: NodePort
---    
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: api-gateway-ingress
spec:
  rules:
  - host:
    http:
      paths:
      - path: /foo
        backend:
          serviceName: foo-service-service
          servicePort: 7779
      - path: /bar
        backend:
          serviceName: bar-service-service
          servicePort: 7776

I can not access the services. kubectl describe shows the following for my ingress:

Name:           api-gateway-ingress
Namespace:      default
Address:        
Default backend:    default-http-backend:80 (<none>)
Rules:
  Host  Path    Backends
  ----  ----    --------
  * 
        /foo    foo-service-service:7779 (<none>)
        /bar    bar-service-service:7776 (<none>)
Annotations:
Events: <none>

Is it because there is not address set for my ingress, that it is not visible to outside world yet?
