Kubernetes Nginx Ingress not finding service endpoint
I'm having some trouble getting the Nginx ingress controller working in my Kubernetes cluster. I have created the nginx-ingress deployments, services, roles, etc., according to https://kubernetes.github.io/ingress-nginx/deploy/
I also deployed a simple hello-world
app which listens on port 8080
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: hello-world
namespace: default
spec:
selector:
matchLabels:
name: hello-world
template:
metadata:
labels:
name: hello-world
spec:
containers:
- name: hello-world
image: myrepo/hello-world
resources:
requests:
memory: 200Mi
cpu: 150m
limits:
cpu: 300m
ports:
- name: http
containerPort: 8080
protocol: TCP
And created a service for it
kind: Service
apiVersion: v1
metadata:
namespace: default
name: hello-world
spec:
selector:
app: hello-world
ports:
- name: server
port: 8080
Finally, I created a TLS secret (my-tls-secret
) and deployed the nginx ingress per the instructions. For example:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
name: hello-world
namespace: default
spec:
rules:
- host: hello-world.mydomain.com
http:
paths:
- path: /
backend:
serviceName: hello-world
servicePort: server
tls:
- hosts:
- hello-world.mydomain.com
secretName: my-tls-cert
However, I am unable to ever reach my application, and in the logs I see
W0103 19:11:15.712062 6 controller.go:826] Service "default/hello-world" does not have any active Endpoint.
I0103 19:11:15.712254 6 controller.go:172] Configuration changes detected, backend reload required.
I0103 19:11:15.864774 6 controller.go:190] Backend successfully reloaded.
I am not sure why it says Service "default/hello-world" does not have any active Endpoint
. I have used a similar service definition for the traefik ingress controller without any issues.
I'm hoping I'm missing something obvious with the nginx ingress. Any help you can provide would be appreciated!

I discovered what I was doing wrong. In my application definition I was using name
as my selector
selector:
matchLabels:
name: hello-world
template:
metadata:
labels:
name: hello-world
Whereas in my service I was using app
selector:
app: hello-world
After updating my service to use app
, it worked
selector:
matchLabels:
app: hello-world
template:

labels:
app: hello-world
