I have created small nginx deployment and type as LoadBalancer in Azure Kubernetes service, but I was unable to access the application using LoadBalaner service. Can some one provide the solution
I have already updated security group to allow all traffic, but no use.
Do I need to update any security group to access the application?
Please find the deployment file.
cat nginx.yml
apiVersion: v1
kind: Service
metadata:
name: nginx-kubernetes
spec:
type: LoadBalancer
ports:
- port: 8080
targetPort: 8080
selector:
app: hello-kubernetes
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-kubernetes
spec:
replicas: 3
selector:
matchLabels:
app: hello-kubernetes
template:
metadata:
labels:
app: hello-kubernetes
spec:
containers:
- name: hello-kubernetes
image: nginx:latest
ports:
- containerPort: 8080Nginx container is using port 80 by default and you are trying to connect to port 8080 where nothing is listening and thus getting connection refused.
Take a look here at nginx conateiner Dockerfile. What port do you see?
All you need to do to make it work is to change target port like following:
apiVersion: v1
kind: Service
metadata:
name: nginx-kubernetes
spec:
ports:
- port: 8080
targetPort: 80
selector:
app: hello-kubernetesAdditionally it would be nice to change containerPort as following:
spec:
containers:
- name: hello-kubernetes
image: nginx:latest
ports:
- containerPort: 80
