Not able to acess the application running inside kind cluster

[rabindragogoi]

I have an applcation with the below deployment file:
apiVersion: apps/v1 kind: Deployment metadata: name: flask-app-deployment namespace: default spec: replicas: 1 selector: matchLabels: app: flask-app-deployment template: metadata: labels: app: flask-app-deployment spec: containers: - name: test-app image: localhost:5001/learn:01 resources: limits: memory: "128Mi" cpu: "500m" ports: - containerPort: 8399

2. Created a service .
   kubectl expose deployment flask-app-deployment --type=NodePort --name=my-service
   But I am not able to access my application. While I do kubectl get deployments and get services, it shows everything is fine.

The only way I am able to run the application i when I run separately port forwarding. command.
kubectl port-forward flask-app-deployment-74b5c95c56-rj5mf 8399:8399
How can I run the application without port forwarding and put whatever needed in service.yaml file?
Please help.

what platform are you on?

on mac/windows you'll have to use some form of port forwarding. you can do https://kind.sigs.k8s.io/docs/user/configuration/#extra-port-mappings + a node port, see e.g. https://kind.sigs.k8s.io/docs/user/ingress/

on linux you can typically use the node container IPs and access the nodeports at $container_ip:$port

is there a reason kubectl port-forward is insufficient? it's a pretty simple and portable option.

Hey @BenTheElder : Thanks for the suggestion. I am able to access my application without port forwarding separately in a command.

Would like to know that the same process will work for load balancer as well?

closing the issue Thanks

LoadBalancer API doesn't really map well to pre-defined forwards of specific ports https://kind.sigs.k8s.io/docs/user/loadbalancer/

We're working on something else in #3086

In the meantime this approach does work https://kind.sigs.k8s.io/docs/user/ingress/
