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.

Context
An existing Pod needs to be integrated into the Kubernetes built-in logging architecture (e. g. kubectl logs). Adding a streaming sidecar container is a good and common way to accomplish this requirement.
Task
Add a sidecar container named sidecar, using the busybox Image, to the existing Pod big-corp-app. The new sidecar container has to run the following command:
/bin/sh -c tail -n+1 -f /va r/log/big-corp-app.log
Use a Volume, mounted at /var/log, to make the log file big-corp-app.log available to the sidecar container.
Solution:
Solution:
#
kubectl get pod big-corp-app -o yaml
#
apiVersion: v1 kind: Pod metadata:
name: big-corp-app spec:
containers:
- name: big-corp-app image: busybox
args:
- /bin/sh
- -c
- > i=0;
while true; do
echo "$(date) INFO $i" >> /var/log/big-corp-app.log; i=$((i+1));
sleep 1; done
volumeMounts:
- name: logs mountPath: /var/log
- name: count-log-1 image: busybox
args: [/bin/sh, -c, 'tail -n+1 -f /var/log/big-corp-app.log'] volumeMounts:
- name: logs mountPath: /var/log volumes:
- name: logs emptyDir: {
}
#
kubectl logs big-corp-app -c count-log-1
