Does my app need an ingress?
Is your application public or private?
If your application is public then you’ll need to configure an ingress making sure you’ve considered the security implications associated with this.
If not then you don’t need an ingress, this is also true if your application is being called by another application within the cluster, you can use the internal service address. Your service address is in the format:
<service-name>.<namespace>.svc.cluster.local
You can query your service using kubectl -n $namespace describe service $yourservice.
Applications in development
If your application is in development and contains sensitive information or requires authentication but does not have it set up then adding an ingress may not be a good idea.
Port Forwarding
Instead of opening up your development application to the world you can instead use Kubernetes built in port forwarding. This feature forwards the port defined in your service to your local machine:
kubectl -n $namespace port-forward 8080:8080
This will forward your applications port 8080 to your local machines port 8080. If you visit localhost:8080 in your browser you should see your development application.
