?? Kubernetes Interview Question & Pro Tips: Mastering Static Pods! ??

?? Kubernetes Tip of the Day: Understanding Static Pod Definitions! ??

?? Q: What is the path of the directory holding the static pod definition files?

?? Step 1: Identify the kubelet config file:

 ps -aux | grep /usr/bin/kubelet        

?? Output Example:

--config=/var/lib/kubelet/config.yaml        

?? Step 2: Check the staticPodPath in the kubelet config file:

grep -i staticpod /var/lib/kubelet/config.yaml        

? Result:

staticPodPath: /etc/kubernetes/manifests        

??? Path Found: /etc/kubernetes/manifests

?? Note: The path may vary. Always check the kubelet configuration file!

?? Q: How to delete a static pod named static-redbox?

1?? Find the node with the pod:

kubectl get pods --all-namespaces -o wide | grep static-redbox        

2?? SSH into the identified node:

ssh <node_name>        

3?? Identify the kubelet config file:

ps -ef | grep /usr/bin/kubelet        

4?? Find the staticPodPath:

grep -i staticpod /var/lib/kubelet/config.yaml        

5?? Navigate to the directory:

cd <output_path>        

6?? Delete the static pod file:

rm -rf static-redbox.yaml        

7?? Logout from the node:

ctrl+d or exit        

8?? Verify deletion: Check if the pod is deleted!

?? Pro Tip: By default, static pods are usually created for control plane components, so look on the control plane node first!
