Kubernetes CKA sample exam question 7 with answer

Question
Create a static pod on node01 called static-nginx with image nginx and make sure that it is recreated/restarted automatically in case of any failures happening.

Answer
Get the environment status:

kubectl get nodes

as we saw from output we have 2 nodes cluster: controlplane and node01
SSH to node01:

ssh node01

Get kubelet configuration config file:

ps aux|grep kubelet

get the configuration path from --config switch - in this case it is /var/lib/kubelet/config.yaml
Get the static pods path:

cat /var/lib/kubelet/config.yaml|grep staticPod

in this case the path it is /etc/kubernetes/manifests
Go inside this folder and create a manifest for our static pod. The file path is /etc/kubernetes/manifests/1-nginx-static.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: static-nginx
spec:
  containers:
  - name: nginx-container
    image: nginx

Save the file and exit node01.
Check the pods:

kubectl get po

you will notice that the static pod is getting created
