Hi Raghav, I have 1 suggestion , it will help us in learning more quickly. "Instead of Simply copying the commands, if you can explain commands as well, it will great help". For example, I noticed while joining worker node with master , you ran that command. It will be great if you can explain those commands as well. I agree there commands are already suggested and we have to copy only. But to get good idea of k8s , it is also required how & from where command values are coming. But really appreciate your efforts .
Hello, I have some questions to ask. I followed all of your steps and they were very clear. However, in the reference documentation that you provided, the command has changed on the website. The 'replicas' command is no longer available. I also typed the exact same command as shown in the video, but I still encounter an error. It would be really helpful if you could update the command or provide some guidance. Thank you very much for your great video; it explains all the steps very well. I wanted to express my appreciation
hii, the content i loved it, but i am facing one issue that you are taking the copy of all the commands but when i try to copy the commands from this play ground it is not showing to me to take copy.pls mention how to take the copy.
Hi, I keep getting "The connection to the server 192.168.0.13:6443 was refused - did you specify the right host or port? " when I tried to initialize cluster network
Hi Saranya, you can assign pods to nodes This will help kubernetes.io/docs/tasks/configure-pod-container/assign-pods-nodes/ kubernetes.io/docs/concepts/configuration/manage-resources-containers/
there is a question - suppose we have have created a pod and a nodePort service to access application deployed on this pod . Can we access the app running on the pod via the nodePort service in Play-with-k8 website . If yes then how ?

Hi Raghav, I am unable to create the pods. Getting the error mentioned below. Could you please help. [node3 ~]$ kubectl run my-nginx --image=nginx --replicas=2 error: unknown flag: --replicas
Asha The error message "error: unknown flag: --replicas" indicates that Kubernetes does not recognize the `--replicas` flag. This is because the `kubectl run` command has been deprecated and replaced with the `kubectl create deployment` command. To create a deployment with two replicas, you can use the following command: ``` kubectl create deployment my-nginx --image=nginx --replicas=2 ``` This will create a deployment named `my-nginx` with two replicas. Kubernetes will then create and manage the pods for you. Here is an example of how to create a deployment with two replicas using the `kubectl create deployment` command: ``` # Create a deployment named my-nginx with two replicas of the nginx image kubectl create deployment my-nginx --image=nginx --replicas=2 # Get the pods for the deployment kubectl get pods -l app=my-nginx # This will show two pods running the nginx image ``` I hope this helps

Hi Raghav,
I am unable to create the pods. Getting the error mentioned below. Could you please help.
[node3 ~]$ kubectl run my-nginx --image=nginx --replicas=2
error: unknown flag: --replicas
Asha
The error message "error: unknown flag: --replicas" indicates that Kubernetes does not recognize the `--replicas` flag. This is because the `kubectl run` command has been deprecated and replaced with the `kubectl create deployment` command.
To create a deployment with two replicas, you can use the following command:
```
kubectl create deployment my-nginx --image=nginx --replicas=2
```
This will create a deployment named `my-nginx` with two replicas. Kubernetes will then create and manage the pods for you.
Here is an example of how to create a deployment with two replicas using the `kubectl create deployment` command:
```
# Create a deployment named my-nginx with two replicas of the nginx image
kubectl create deployment my-nginx --image=nginx --replicas=2
# Get the pods for the deployment
kubectl get pods -l app=my-nginx
# This will show two pods running the nginx image
```
I hope this helps
@@RaghavPal Thanks Raghav. Your teaching is very good and easily understandable. Could you please let me know if you conduct any DevOps classes?
