Kubernetes - services without selector

Question

I\'m struggling with Kubernetes\' service without a selector. The cluster is installed on AWS with the kops. I have a deployment with 3 nginx pods exposing port 80:

Answer 1

As @iliefa mentioned in his comment above, the below part of the definition is treated as labels in this type of cases.

ports:
    - port: 80
      name: http

In your scenario, we need to either remove 'name: http' as mentioned by @iliefa or we need to add 'name: http' under 'ports:' in the service definition as you can spot below.

apiVersion: v1
kind: Service
metadata:
  name: dummy-svc
  labels:
    app: nginx
spec:
 ports:
    - protocol: TCP
      port: 80
      targetPort: 80
      name: http

Answer 2

it works if you remove the "name" field from the endpoints configuration. it should look like this:

apiVersion: v1
kind: Endpoints
metadata:
  name: dummy-svc 
subsets: 
  - addresses:
    - ip: 172.17.0.4
    - ip: 172.17.0.5
    - ip: 172.17.0.6
    ports:
    - port: 80

Answer 3

correct the service definition as below

apiVersion: v1
kind: Service
metadata:
  name: dummy-svc
  labels:
    app: nginx
spec:
  ports:
  - protocol: TCP
    port: 80
    targetPort: 80
  selector:
   app: nginx
