List all the pods showing name and namespace with a json path expression

Set the node named ek8s-node-1 as unavailable and reschedule all the pods running on it.

Perform the following tasks:

• Add an init container to hungry-bear (which has been defined in spec file /opt/KUCC00108/pod-spec-KUCC00108.yaml)
• The init container should create an empty file named/workdir/calm.txt

Task

Create a new PersistentVolumeClaim

• Name: pv-volume

• Class: csi-hostpath-sc

• Capacity: 10Mi

Create a new Pod which mounts the PersistentVolumeClaim as a volume:

• Name: web-server

• Image: nginx

• Mount path: /usr/share/nginx/html

Configure the new Pod to have ReadWriteOnce access on the volume.

Finally, using kubectl edit or kubectl patch expand the PersistentVolumeClaim to a capacity of 70Mi and record that change.

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.

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
