Kubernetes Load Balancer Type not responding to External IP Address - kubernetes

Question

I've been trying to use the below to expose my application to a public IP. This is being done on Azure. The public IP is generated but when I browse to it I get nothing.
This is a Django app which runs the container on Port 8000. The service runs at Port 80 at the moment but even if I configure the service to run at port 8000 it still doesn't work.
Is there something wrong with the way my service is defined?
apiVersion: v1
kind: Service

name: web
labels:
app: hmweb
spec:

- port: 80

app: hmweb
tier: frontend

Answer 1

The reason behind that is your service has two selector app: hmweb and tier: frontend and your deployment pods has only single label named app: hmweb. Hence when your service is created it could not find the pods which has both the labels and doesn't connect to any pods. Also, if you have container running on 8000 port then you must define targetPort which has the value of container port on which container is running, else it will take both targetPort and port value as same you defined in your service i.e. port: 80
The correct yaml for your deployment is:
apiVersion: v1
kind: Service
metadata:
name: web
labels:
app: hmweb
spec:
ports:
- port: 80
targetPort: 8000
protocol: TCP
selector:
app: hmweb
type: LoadBalancer
Hope this helps.
