Static Pods-Kubernetes Certification- Crack the CKA with WeMakeDevOps.

Static Pods are managed directly by the kubelet daemon on a specific node, without the API server observing them.

Problem :  Static pod creation in a specified node in a given k8 cluster.  Note:  Managed by Kubeadm




Twist 1: it will be in a worker node not in master node


Create a pod manifest file in master node  



Note: Here i am doing in default namespace

kubectl run --generator=run-pod/v1 nginx --image=nginx --dry-run  -o yaml  


Put out put in test.yaml file


Copy file in given worker node


scp test.yaml node01:/etc/kubernetes/manifests


ssh to that node to execute kubelet daemon.



Twist: 2


There is no static pod directory defined in /var/lib/kubelet/config.yaml for that particular node ,


Solution:
a)
You need to add below line in above file in /var/lib/kubelet/config.yaml


staticPodPath: /etc/kubernetes/manifests


b than just copy pod.yaml in /etc/kubernetes/manifests


c Restart the Kubelet if required do daemon restart as well.


service kubelet stop
service kubelet start


Check on the master node that static pod created or not in default namespace .
