1. pods-creation
2. pods-replication

You create a pod and create replicaset

kubectl create -f pods.yml
kubectl create -f pods_replica_run_with_pods.yml

Or you can create a replicaset which will create desired no of pods.

kubectl create -f pods_replica.yml

See, containerPort & Kubernetes site

https://kubernetes.io/docs/tasks/access-application-cluster/service-access-application-cluster/ Deploy pods_nodeport.yml

kubectl expose deployment hello-world --type=NodePort --name=example-service

In GKE, Services & Incress (page) -> Port -> Port forwarding

See this

https://kubernetes.io/docs/tutorials/stateless-application/expose-external-ip-address/

Go to folder

Deploy blue.yml & blue_svc.yml. Connect the service,

kubectl describe svc bg-service

Deploy green.yml. Check the pod list

kubectl get pods -o wide

Connect the service. It is pointing towards blue.

Deploy green_svc.yml. Connect the service. It is pointing towards green.

kubectl apply -f pods_node.yml

kubectl expose deployment hello-world --type=NodePort --name=node-svc

kubectl apply -f pods_nodeport_ingress.yml

This will create a ingress controller but we cannot access it.

Create an ingress loadbalancer, https://kubernetes.github.io/ingress-nginx/deploy/#prerequisite-generic-deployment-command

Internet is full with example which works perfectly on minikube. But having ingress on minikube is not same as on cloud. Public IP doesnot exist on minikube. Which is big missing part.

Easiest working example with public IP, is at https://cloud.google.com/kubernetes-engine/docs/tutorials/configuring-domain-name-static-ip#config-connector_1
