Accessing kubernetics service from outside pod but within the cluster
Question
Am running several services on same port within my kubernetes cluster; so its like ser1, ser2, ser3 all using same port 8080. I can access these services from inside a pod as <serv-name>:8080 but can I also access them in same way from one of the host nodes ie outside a container but from one of the cluster nodes ?
I tried looking around but did not find any relevant discussion on this. Pls if someone may suggest.
my sample config
apiVersion: v1
kind: Service
metadata:
name: svc1
namespace: sample
labels:
app: svc1
spec:
selector:
app: app1
ports:
- name: psvc1
port: 8080
targetPort: 9090
protocol: TCP

as Dries said, using cluster IP we can access the service from node.
kubectl run nginx --image=nginx --port=80 --expose=true
kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 9d
nginx ClusterIP 10.103.206.246 <none> 80/TCP 52m
# curl 10.103.206.246:80
