Thanks for the clear explanation.. seen many videos but I must tell this one is better to understand the concept. Specially I've gone through the spring boot helm chart session. that has helped me a lot to recreate the chart for my application.. thanks again.. keep on the good work.
Glad it was helpful!

Hi, Rahul It was very clear and thank you so much for making this video🤝🤝👌👌Please make a clear video for monitoring Kubernetes cluster by using Prometheus and Grafana..... Thanks in advance 😍
Sure I will prepare something around prometheus and grafana
Hi @@RahulWagh, if you have already prepared regarding above request please share us link. looking forward to hearing from you.
Hey karthik it is still in my bucket list just not getting the time to prepare it but it will be there on my channel in next week
what if we have configmap.yaml as one more k8s file, how to proceed in that case?
Thanks for amezing video. Do we need to open loadbalancer port 8080 in the firewall rule or its automatically getting added while accessing application from internet
Port 8080 does not get added automatically into the firewall, so incase if you are not able to access the application due the firewall blocking your port. Then please add port 8080 to firewall.

When we are hitting the ip so why we are using hello ? i am new so I am not getting.. please explain !!
Thank you very much for sharing your in-depth knowledge - Is there a special reason that you are using k8s 1.16 ? also when you ran kubectl get nodes - I do not see master node ! - is that a special cluster.
You are welcome. There is no special reason for using k8s 1.16, it’s just I had it setup already on my laptop for long time and did not upgrade it. Regarding the master node yeah it’s my local development cluster on which I do lots of POC and experiments but the core concepts on converting k8s to helm still remains the same.
But thanks for mentioning I will upgrade my k8s.

Rahul thanks for posting the video. I have got 4 questions . 1) For image you have mentioned "rahulwagh17/kubernetes:jhooq-k8s-springboot" , from where is the image getting downloaded as I don't see URL. 2) Can I replace image with say for example Centos from Docker hub? 3) Whats the default image repository for HELM ? Can I put multiple image locations , does it require username/password for repository/Hub?
Good content, thanks!
Suppose I've 30 java services for which we've respective yamls of deployments/services etc.
How do you suggest to deploy all 30 services using helm chart? Different chart for each service? or anyway we can use single chart to deploy all services.
Thanks chetan!
But let me ask you some questions on your 30 java services -
1. Does all the 30 services are packed inside one docker container ?
2. Do you have 30 different container for 30 java services?
//Rahul
@@RahulWagh
30 java services = 30 yamls of k8s deployment & k8s services
so any java service is running with 1 k8s deployment with x number of pods. Any pod contains 1 container in it.
I hope I've made it clear.
I can think of one solution where you need to create your own values.yaml which will contain all the 30 entries of your java services.
You can iterate values.yaml and then deploy inside kubernetes cluster using helm chart.
here is the reference example - jhooq.com/helm-pass-environment-variables/#22-iterate-over-key-value-map
//Rahul
sir what does the targetport:http means ?
targetPort: This is the port on the pod that the Service or Ingress should forward traffic to.
It’s where your application inside the pod is actually listening for traffic.
It is very clear but I doubt that which helm version you installed in the k8s cluster
I am using the helm 3 but its been a long time when i recorded the video so it must be 3.x or higher
HI it was wonderful lecture i just have one doubt, while accessing the application through web, your giving "hello" what does that mean ? i appreciate your reply, Thanks
when I install the helm namespace show not be default it shows have other names
Hi sir
I thought that you are going to teach how to convert existing deployment.yaml to helm, the description is a misnomer
I still have not understood the significance of _helpers.tpl file, can you please help? Thanks a lot.
how add namespace in helm
could you please let me know how to write liveness probe and readiness probe in helm charts
Hi,
I will be preparing the session on liveness and readiness prob because you have to update at multiple places in yaml so it’s bit hard to explain here
@@RahulWagh hi Rahul,any progress here?
My name is thirupathi
How to write helm chart for docker compose file
Can you give idea
how to done multiple deployments with one helm chart ?
Well you need to play around values.yaml, first you need to create variable which will have list of deployment which you wanna perform for example - deploy-springboot-1, deploy-springboot-2, deploy-nodejs-3 etc....
Later you need to iterate over that variable inside your deployment.yaml and service.yaml.
It just food for thought but this is the approach i would take. Let see if i can prepare some lab session around it in upcoming days
@@RahulWagh can you make a video for that?? I think its more helpful
Yeah surely i will prepare one but can not promise the exact date but soon i will prepare something around that
@@RahulWagh thnks so much
He is niranjan right
What?
When we are hitting the ip so why we are using hello ? i am new so I am not getting.. please explain !!
