Google Kubernetes Engine Ingress UNHEALTHY backend service - docker

Question

Kind Note: I have googled a lot and take a look too many questions related to this issue at StackOverflow also but couldn't solve my issue, that's why don't mark this as duplicate, please!
I'm trying to deploy 2 services (One is Python flask and other is NodeJS) on Google Kubernetes Engine. I have created two Kubernetes-deployments one for each service and two Kubernetes-services one for each service of type NodePort. Then, I have created an Ingress and mentioned my endpoints but Ingress says that One backend service is UNHEALTHY.
Here are my Deployments YAML definitions:
# Pyservice deployment
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: pyservice
labels:
app: pyservice
namespace: default
spec:
selector:
matchLabels:
app: pyservice
template:
metadata:
labels:
app: pyservice
spec:
containers:
- name: pyservice
image: docker.io/arycloud/docker_web_app:pyservice
ports:
- containerPort: 5000
imagePullSecrets:
- name: docksecret
# # Nodeservice deployment
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: nodeservice
labels:
app: nodeservice
namespace: default
spec:
selector:
matchLabels:
app: nodeservice
template:

labels:
app: nodeservice
tier: web
spec:
containers:
- name: nodeservice
image: docker.io/arycloud/docker_web_app:nodeservice
ports:
- containerPort: 8080
imagePullSecrets:
- name: docksecret
And, here are my services and Ingress YAML definitions:
# pyservcie service
kind: Service
apiVersion: v1
metadata:
name: pyservice
spec:
type: NodePort
selector:
app: pyservice
ports:
- protocol: TCP
port: 5000
nodePort: 30001
---
# nodeservcie service
kind: Service
apiVersion: v1
metadata:
name: nodeservcie
spec:
type: NodePort
selector:
app: nodeservcie
ports:
- protocol: TCP
port: 8080
nodePort: 30002
---
# Ingress
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: my-ingress
namespace: default
annotations:
kubernetes.io/ingress.class: "gce"
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- http:
paths:
- path: /
backend:
serviceName: pyservice
servicePort: 5000
- path: /*
backend:
serviceName: pyservice
servicePort: 5000
- path: /node/svc/
backend:
serviceName: nodeservcie
servicePort: 8080
The pyservice is working fine but the nodeservice shows as UNHEALTHY backend. Here's a screenshot:
Even I have edited the Firewall Rules for all gke-.... and allow all ports just for getting out from this issue, but it still showing the UNHEALTHY status for nodeservice.
What's wrong here?
Thanks in advance!

Answer 1

Why are you using a GCE ingress class and then specifying a nginx rewrite annotation? In case you haven't realised, the annotation won't do anything to the GCE ingress.
You have also got 'nodeservcie' as your selector instead of 'nodeservice'.
