Cannot make the nginx-ingress controller work with Kubernetes cluster
I wanted to test out NGINX Ingress Controller one click installation on digital-ocean, so I deployed a very simple app and created several Kubernetes resource as the following:
apiVersion: apps/v1 kind: Deployment metadata: name: app-test spec: replicas: 1 selector: matchLabels: app: app-test template: metadata: labels: app: app-test spec: containers: - name: app-test image: <my-image-from-docker-hub> ports: - containerPort: 80 imagePullPolicy: Always
apiVersion: networking.k8s.io/v1beta1 kind: Ingress metadata: name: ingress-app-test spec: backend: serviceName: app-test servicePort: 80
apiVersion: v1 kind: Service metadata: name: app-test spec: selector: app: app-test ports: - port: 80 targetPort: 80
The container that runs is a very simple web application that works just fine, also port-forwarding to it works just fine.
However, when I try to access the external IP of the load balancer that is deployed as part of the nginx-ingress I expect to see the homepage of the web application but I just get 503 error from nginx.
Looking at the logs of the nginx ingress controller, I can see an error indicating:
Error creating upstream "ingress-nginx-app-test-80": no object matching key "ingress-nginx/app-test" in local store
What I am missing here ?
