NO.20 Set the node namedek8s-node-1asunavailable and reschedule all thepods running on it.

NO.21 Create a snapshot of theetcdinstance running at , saving thesnapshot to the file path
/srv/data/etcd-snapshot.db.
The following TLScertificates/key are suppliedfor connecting to the server withetcdctl:
* CA certificate:/opt/KUCM00302/ca.crt
* Client certificate:/opt/KUCM00302/etcd-client.crt
* Client key:Topt/KUCM00302/etcd-client.key

NO.22 Configure the kubelet systemd- managed service, on the node labelled with name=wk8s-node-1, to launch a pod containing a single container of Image httpd named webtool automatically. Any spec files required should be placed in the /etc/kubernetes/manifests directory on the node.
You can ssh to the appropriate node using:
[student@node-1] $ ssh wk8s-node-1
You can assume elevated privileges on the node with the following command:
[student@wk8s-node-1] $ | sudo -i

NO.23 List all service account and create a service account called “admin”

NO.24 A Kubernetes worker node, named wk8s-node-0 is in state NotReady. Investigate why this is the case, and perform any appropriate steps to bring the node to a Ready state, ensuring that any changes are made permanent.
You can ssh to the failed node using:
[student@node-1] $ | ssh Wk8s-node-0
You can assume elevated privileges on the node with the following command:
[student@w8ks-node-0] $ | sudo -i

NO.25 How can an administrator configure the NGFW to automatically quarantine a device using Global Protect?

NO.26 Scale the deployment webserver to 6 pods.

NO.27 Delete the above pod and create again from the same yaml file
and verifies there is no “test-file.txt” in the path /data/redis
(Since non-persistent storage “emptyDir” is used).

NO.28 List all the pods showing name and namespace with a json path expression

NO.29 Create a redis pod and expose it on port 6379

NO.30 Score: 7%

Task
Given an existing Kubernetes cluster running version 1.20.0, upgrade all of the Kubernetes control plane and node components on the master node only to version 1.20.1.
Be sure to drain the master node before upgrading it and uncordon it after the upgrade.

You are also expected to upgrade kubelet and kubectl on the master node.

NO.31 Create and configure the servicefront-end-serviceso it’s accessiblethroughNodePortand routes to theexisting pod namedfront-end.

NO.32 create a pod in a specific node (node1) by placing the pod definition file in a particular folder “/etc/kubernetes/manifests”.

NO.33 Get all the pods with label “env”

NO.34 Create an nginx pod and list the pod with different levels of verbosity

NO.35 Create a file:
/opt/KUCC00302/kucc00302.txtthatlists all pods that implement servicebazin namespacedevelopment.
The format of the file should be onepod name per line.

NO.36 Get the pods with labels env=dev and env=prod and output the labels as well

NO.37 Get list of all the nodes with labels

NO.38 Check the image version in pod without the describe command

NO.39 Create a namespace called ‘development’ and a pod with image nginx called nginx on this namespace.

NO.40 Create a redis pod, and have it use a non-persistent storage
(volume that lasts for the lifetime of the Pod)

NO.41 Create a pod that having 3 containers in it? (Multi-Container)

NO.42 Create a Kubernetes secret as follows:
Name: super-secret
password: bob
Create a pod named pod-secrets-via-file, using the redis Image, which mounts a secret named super-secret at /secrets.
Create a second pod named pod-secrets-via-env, using the redis Image, which exports password as CONFIDENTIAL

NO.43 Score: 7%

Task
Create a new NetworkPolicy named allow-port-from-namespace in the existing namespace echo. Ensure that the new NetworkPolicy allows Pods in namespace my-app to connect to port 9000 of Pods in namespace echo.
Further ensure that the new NetworkPolicy:
* does not allow access to Pods, which don’t listen on port 9000
* does not allow access from Pods, which are not in namespace my-app

NO.44 List all the pods sorted by name
