if in event is not showing what to do

[@K21Academy]

If pod events are not displaying in Kubernetes, several factors could be at play. Insufficient permissions, cluster issues, event retention policies, misconfigured logging or monitoring setups, or API server problems might be causing this. To troubleshoot, ensure proper permissions, check the cluster's health, review logging configurations, and verify the event retention policy.

Awesome buddy 💖💐💐💐🙏🙏🙏

At 34:00 duration, just need one clarification. While editing command 'echo' under demo pod . Can we just run command kubectl replace --force -f (temporary file generated.yaml) ------------as its not allowing us to edit the original demo pod YAML file. Is this fine from exam point of view as here i am forcefully deleting existing pod and replacing the same with new one ? Kindly confirm.

[@K21Academy]

Yes, you can do that as well.

[@Ca-happy]

Thank you

[@nirmalanirmala-vn5wo]

Thanks😊

[@K21Academy]

Welcome 😊

[@aditigupta1150]

At 17.00 duration, why you perform the steps to move apiserver.yaml file . I think you can skip this step because as far as i know if we modify/update anything under kube-apiserver.yaml file then kubeadm tool will automatically restart kube-apiserver static pod. Sorry, you can correct me in case if I am wrong.

[@K21Academy]

Hi! Actually we are moving the file out of the location where kubelet will look and it won't find it there then once the file is available then it will restart the pod. This is just one way of restarting the static pods. .. Yes you are correct we have other ways too as the video explains. Thank you

[@nafees-l9e]

Can u guide me on the error that kubelet is activating......... Please guide sir

[@K21Academy]

Please Verify the kubelet configuration files (kubelet.conf or /etc/kubernetes/kubelet) to ensure they are correctly set up. Common configuration issues include incorrect API server endpoints, certificates, or improper flags. And try restarting kublet

[@nafees-l9e]

why suddenly error came like did u specify right host or port came in between .... suddenly api-server stop working in between ................. its fluctuating like situation came in between please guide in this sir.......................... cant get any proper solution over the internet

[@K21Academy]

To start using the cluster set the environment variable $ cp /etc/kubernetes/admin.conf $HOME/ $ chown $(id -u) $HOME/admin.conf $ export KUBECONFIG=$HOME/admin.conf $ echo 'export KUBECONFIG=$HOME/admin.conf' >> $HOME/.bashrc try this if does not work then try kubeadm reset.
