I am new to Kubernetes and was testing a sample deployment. The following is the output from the kubectl get services command. After I deployed the application thru a deployment yml it completes successfully and the pods are provisioned. Now I go to EXTERNAL-IP:80 but I don't get a response and the page keeps spinning.
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
demotest2 LoadBalancer XX.X.XX.XX XX.XXX.XXX.XX 80:30904/TCP 35m
Please let me know if I need to provide more information.
From the message you provided, there are two possible reasons. One is that the pod of your deployment does not run well. It means your image which hosts your application does not work as you want. For this, you need to check if your image can work well locally. Another one is that the demotest2 service does not route the request to the pod of your deployment. For this, you need to check if the selector of the service was set correctly for your pod.
For example:
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
selector:
matchLabels:
run: nginx1
replicas: 1
template:
metadata:
labels:
run: nginx1
spec:
containers:
- name: nginx
image: nginx:latest
ports:
- containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
name: nginx-service
spec:
type: LoadBalancer
ports:
- name: test1
port: 80
targetPort: 80
selector:
run: nginx1In this example, the pods of the deployment use the label run: nginx1, so you need to set the selector of the service as run: nginx1.
