Hi , can you please make more video for kubernetes service .

[@Javatechie]

Okay i will

[@ThomasMchs]

Thanks a lot for the video. If we add replica set, should we still set a fixed port on the spring app?

[@Javatechie]

No not required once your app runs on contains service will take care assigning them DNS

[@__nitinkumar__]

Sir, what is cluster IP? Is the application running of your local system or it has been deployed to some server where people can access ?

[@Javatechie]

Cluster ip is a service type in k8s .

[@raghuvardhansaripalli9636]

Hi Basant, is it possible for you to do a session on creating 2 or 3 node cluster using Ubuntu as well. Because in reality all of us work in Ubuntu or Linux platform instead of windows. God bless you.. !!! Thank you in advance.

[@Javatechie]

Hi Raghu definitely I will try this.

[@ainigma100]

Thank you for the great tutorial! Is it possible to add an nginx as a load balancer which will handle all requests? Maybe we will have 2 applications and based on the URL nginx will redirect to the correct application. Can we also secure the requests and use tls certificates?

Hi 1 quick question what is the advantage of using minikube then enabling kubernetes on docker desktop; to run minikube also we have to install docker desktop on my machine. so what is the advantage here??

[@Javatechie]

You can also use virtual box instead of Docker desktop.

[@diptarghyachatterjee6018]

When creating the deployment object we mentioned the port as --port :8080 . Now when we expose that deployment object using NodePort service type and try to get the url it is different port. Can you please explain once why is that?

I tried deleting the pod as shown in the video, the new pod does not re-spawn. I only get "Nothing to display here" in the PODS section of the minikube dashboard. Why is that? Do you have a email? I am willing to pay for answers and some education. Thanks
