Question 1

You must connect to the correct host.
Failure to do so may result in a zero score.
[candidate@base] $ ssh Cka000060
Task
Install Argo CD in the cluster by performing the following tasks:
Add the official Argo CD Helm repository with the name argo
The Argo CD CRDs have already been pre-installed in the cluster
Generate a template of the Argo CD Helm chart version 7.7.3 for the argocd namespace and save it to ~/argo- helm.yaml . Configure the chart to not install CRDs.

Question 2

You must connect to the correct host.
Failure to do so may result in a zero score.
[candidate@base] $ ssh Cka000058
Context
You manage a WordPress application. Some Pods
are not starting because resource requests are
too high.
Task
A WordPress application in the relative-fawn
namespace consists of:
. A WordPress Deployment with 3 replicas.
Adjust all Pod resource requests as follows:
. Divide node resources evenly across all 3 Pods.
. Give each Pod a fair share of CPU and memory.

Question 3

Create an nginx pod and list the pod with different levels of verbosity See the solution below.

Question 4

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

Question 5

You must connect to the correct host.
Failure to do so may result in a zero score.
[candidate@base] $ ssh Cka000037
Context
A legacy app needs to be integrated into the Kubernetes built-in logging architecture (i.e.
kubectl logs). Adding a streaming co-located container is a good and common way to accomplish this requirement.
Task
Update the existing Deployment synergy-leverager, adding a co-located container named sidecar using the busybox:stable image to the existing Pod . The new co-located container has to run the following command:
/bin/sh -c "tail -n+1 -f /var/log/syne
rgy-leverager.log"
Use a Volume mounted at /var/log to make the log file synergy-leverager.log available to the co- located container .
Do not modify the specification of the existing container other than adding the required volume mount .
Failure to do so may result in a reduced score.

Correct Answer:

Task Summary
* SSH into the correct node: cka000037
* Modify existing deployment synergy-leverager
* Add a sidecar container:
* Name: sidecar
* Image: busybox:stable
* Command:
/bin/sh -c "tail -n+1 -f /var/log/synergy-leverager.log"
* Use a shared volume mounted at /var/log
* Don't touch existing container config except adding volume mount
Step-by-Step Solution
1## SSH into the correct node
ssh cka000037
## Skipping this will result in a zero score.
2## Edit the deployment
kubectl edit deployment synergy-leverager
This opens the deployment YAML in your default editor (vi or similar).
3## Modify the spec as follows
# Inside the spec.template.spec, do these 3 things:
# A. Define a shared volume
Add under volumes: (at the same level as containers):
volumes:
- name: log-volume
emptyDir: {}
# B. Add volume mount to the existing container
Locate the existing container under containers: and add this:
volumeMounts:
- name: log-volume
mountPath: /var/log
# Do not change any other configuration for this container.
# C. Add the sidecar container
Still inside containers:, add the new container definition after the first one:
- name: sidecar
image: busybox:stable
command:
- /bin/sh
- -c
- "tail -n+1 -f /var/log/synergy-leverager.log"
volumeMounts:
- name: log-volume
mountPath: /var/log
spec:
containers:
- name: main-container
image: your-existing-image
volumeMounts:
- name: log-volume
mountPath: /var/log
- name: sidecar
image: busybox:stable
command:
- /bin/sh
- -c
- "tail -n+1 -f /var/log/synergy-leverager.log"
volumeMounts:
- name: log-volume
mountPath: /var/log
volumes:
- name: log-volume
emptyDir: {}
Save and exit
If using vi or vim, type:
bash
CopyEdit
wq
5## Verify
Check the updated pods:
kubectl get pods -l app=synergy-leverager
Pick a pod name and describe it:
kubectl describe pod <pod-name>
Confirm:
* 2 containers running (main-container + sidecar)
* Volume mounted at /var/log
ssh cka000037
kubectl edit deployment synergy-leverager
# Modify as explained above
kubectl get pods -l app=synergy-leverager
kubectl describe pod <pod-name>
