Ingress vs Load Balancer

Question

I am quite confused about the roles of Ingress and Load Balancer in Kubernetes.

As far as I understand Ingress is used to map incoming traffic from the internet to t

Answer 1

Pods have their own IP:PORT but it is dynamic in nature and changes if deleted or redeployed.

Services are assigned ClusterIPor NodePort(a port in a VM where service resource is created) which can be mapped to set of pods or other backend [see: headless services]

• To access correct Pod use ClusterIP(from within clutser)

• NodePort can be used to access pods from outside of the cluster

LoadBalancer[External/Internal]: provided by cloud providers points to either ClusterIP or NodePort. You can access the service by using LB's IP

LB ~> SERVICE(ClusterIP or NodePort) ~> POD

Ingress resource is an entrypoint to cluster.A LB can listen to ingress rules and can route to specific service.[see this example]

LB(Ingress-managed) ~> SERVICE(ClusterIP or NodePort) ~> POD
