[@salmanriaz7892]

Hi, Many thanks for the video. Its very helpful and i followed it step by step to create a k8 cluster. Could you please also create a video on kubeshpere and similar tools.

How to get dasdboard of K8s service!

[@CarkeySushil]

bro wheb Initialize the Kubernetes cluste with pod-network-cidr it gives a error massage few ports are in use. I killed itd PID and retried it wroked but during Calico CNI and Kubectl deployment from kubectl create -.... code, i am getting error nassage saying my conneting to server time out and port or host inuse what do i do??

[@cherryservers]

Hey, sorry you have troubles with it! Happy to help - however, could you please clarify the issue a bit more? It is a little hard to understand the issue. Cheers!

[@vitusyu9583]

Why do you still have to create the custom resource using the custom resource.yaml file after the calico resources are created?

[@cherryservers]

Hey, the custom-resource.yaml file only offers customization options for the Calico installation. It does not create any resources on its own. In this example, the yaml file was only used to modify the CIDR to match our pod network. To create resources defined in the custom-resource.yaml file, you, therefore, need to run the "kubectl create -f custom-resources.yaml" command. Hope this helps!

[@badex3301]

Thanks for this detailed video
i followed all the steps but when I got to the point of running the command "sudo systemctl restart kubelet.service" -
i got the error - Failed to restart kubelet.service: Unit kubelet.service not found.
any idea why?

[@cherryservers]

Hey, sorry you had issues with it. The error implies that Kubelet has not been installed. There's a chance you skipped installing the Kubelet package. Please check out the timestamp @21:30 for reference on how to install Kubernetes packages. Hope this helps! :)

[@badex3301]

@@cherryservers but I did!
There’s a new command “snap install kublets -classic” being employed now. After downloading the repository and update apt package, the command you used in this video doesn’t work instead it suggest you use the “snap install kublets” command.

[@user-ds4ys1dk9q]

why kubernetes v1.28 crashes time to time?

[@ivanferrera]

The title of this video should be changed to how to configure host name on Ubuntu. With a side lesson on how to ping another server in Ubuntu, advanced Linux topics.

[@user-pz3cv6tq6v]

Hi, I am having trouble joining the worker node with master node, first time I tried got timeout after 40s, second time I got [ERROR Port-10250]: Port 10250 is in use
[ERROR FileAvailable--etc-kubernetes-pki-ca.crt]: /etc/kubernetes/pki/ca.crt already exists. Is this the issue on worker node? as far as I know, the 10250 port is being used by calico.

[@swapnilbhosale1379]

ubuntu@master-node:~$ sudo systemctl restart kubelet.service
Failed to restart kubelet.service: Unit kubelet.service not found.

[@monica3251]

Wow, it works! Thanks for your work.
