Why is my kubectl loadbalancer targeting to a random port? - kubernetes

Question

I have a service and deployment kube config files like below.
Now, when i apply these two files, its creating a loadbalancer but its targeting to a random port but not port 80.
I'm a newbie to EKS and tried different kube config files but it still tries to target a random port.
service file:
apiVersion: v1
kind: Service
metadata:
name: runners-test
labels:
app: runners-test
spec:
ports:
- port: 80
targetPort: 80
selector:
app: runners-test
type: LoadBalancer
deployment file:
apiVersion: apps/v1
kind: Deployment
metadata:
name: runners-test
labels:
app: runners-test
spec:
replicas: 1
selector:
matchLabels:
app: runners-test
template:
metadata:
labels:
app: runners-test
spec:
containers:
- name: runners-test
image: mylocaldockerimage
ports:
- containerPort: 80
C02X67GOKL:terraform$ kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP > PORT(S) AGE
kubernetes ClusterIP 10.100.0.1 443/TCP 8d
runners-test LoadBalancer 10.100.246.180 af3884a05ad7811e99b0e06a70e73221-192467907.us-west-2.elb.amazonaws.com 80:31038/TCP 43m
It's targeting to port a random port 31038, when i connect to my pod and run ps -ef, i can see that a service is running on port 80.

Answer 1

As mentioned in the Kubernetes Service documentation , setting this type will enforce the underlying cloud provider to assign a public IP address to your service and route the traffic on your exposed port ( which is 80 in your case ) to Node Port ( 31038 ) on the kubernetes cluster level.
On cloud providers which support external load balancers, setting the type field to LoadBalancer provisions a load balancer for your Service.
