My first attemp to resolve "Kubernetes Time Check Pod" in https://engineer.kodekloud.com is not successful. The exercise doesn’t allow to open an editor to edit a yaml file. I had to resort to cat. I attempted several times to resolve it on my local cluster, still no luck even I tried different combination such as command, args,string in string, avoiding expansion. This one from stackoverfow gave me a clue how to resolve my issue.

In the past several days, I practiced several exercises for my coming CKS exam. I noticed that it takes a while to get static pods restart after configuraiton changes. I was curious if there is any faster way to make that happen. I think the following ways definitely will be faster than waiting 3 minutes after I used them for a while. The observable time is shorter than 3 minutes

In the past I learnt a lot of kubernetes, however there is no much information about kubelet or not deep enough. I couldn’t answer the questions about kubelet correctly in an interview. Here I put all the information I collected from the internet here for my references. kubelet component architecture how does kubelet work Container Lifecycle Management Through the CRI kubelet, CRI and CNI sequence diagram kubelet, CRI and CNI interaction diagram The process of creating a pod Handler The work of podWorkers syncPod kubelet Runtime Creating a sandbox for a pod References: https://www.
