I want to access my backend pods using an internal Kubernetes dns name. Instead of using http://somepodip:8080/get I want to use http://backend:8080/get to use my backend.
I am currently running my backend pods and have hooked them up to a service.
kind: Service
apiVersion: v1
metadata:
name: backend
spec:
selector:
app: myapp-backend
ports:
- name: http
protocol: TCP
port: 8080
targetPort: 8080
This does assign my pods to the backend service. But when I try to use a frontend pod with http://backend/get , it does not find the resource.
Am I incorrectly configuring the service?
Your service seems to be ok, the issue could be possibly because your frontend is not server rendered, which means that your browser is trying to lookup for a name backend
, in that case you cannot rely on kubernetes service name as your browser does not recognize it as a valid hostname.
If you want to access externally by instead of ip, you want to use names, check how to setup a ingress entry https://kubernetes.io/docs/concepts/services-networking/ingress/#what-is-ingress
