問題 #82
You have a Deployment running on a Kubernetes cluster with limited resources. How can you adjust the Deployment to use resources more efficiently and prevent resource contention?

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Resource Requests and Limits:
- Set 'requests' and 'limits' for CPU and memory for the containers in the Deployment.
- This helps in specifying the minimum resources required by the pods and the maximum resources that they can consume.

2. Optimize Container Images: - Use smaller and more efficient container images to reduce the resource footprint of the pods. 3. Use Resource Quotas: - Apply resource quotas at the namespace level to control the resource consumption of the pods within a namespace. 4. Consider Pod Disruption Budgets (PDB): - Implement PDBs to control the maximum number of pods that can be unavailable during a rolling update or pod deletion. - This ensures that the application remains available during resource-intensive events. 5. Utilize Node Affinity and Tolerations: - Configure node affinity and tolerations to schedule pods on specific nodes that have the required resources. 6. Monitor Resource Utilization: - Regularly monitor the resource utilization of the cluster and the pods. - Use tools like 'kubectl top pods', 'kubectl top nodes', and 'kubectl describe nodes' to gather resource utilization data. - Adjust resource requests and limits accordingly based on the monitoring data.


問題 #83
Create a pod that echo "hello world" and then exists. Have the pod deleted automatically when it's completed See the solution below.

答案：

解題說明：
kubectl run busybox --image=busybox -it --rm --restart=Never --
/bin/sh -c 'echo hello world'
kubectl get po # You shouldn't see pod with the name "busybox"


問題 #84
Monitor the logs of pod foo and:
* Extract log lines corresponding unable-to-access-website
* Write them to/opt/KULM00201/foo

答案：

解題說明：
See the solution below.
Explanation
solution


問題 #85
You have a Deployment named 'web-app' running a web application with two pods. The web application is configured to access a database with the connection string stored in a ConfigMap named 'db- config'. You need to update the database connection string in the ConfigMap without restarting the pods.

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Update the ConfigMap:
- Modify the 'db-config' ConfigMap to include the new connection string. This can be done using 'kubectl patch' or 'kubectl edit' commands. For instance, using 'kubectl patch':
kubectl patch configmap db-config -p '{"data": {"db-connection-string": "new-connection-string"}}'
2. Verify the Updated ConfigMap:
- Confirm the changes were applied to the ConfigMap by checking its data with 'kubectl get configmap db- config -o yaml':
kubectl get configmap db-config -o yaml
This should show the updated 'db-connection-string' value.
3. Observe the Pods:
- Monitor the pods in the 'web-app' Deployment. Since ConfigMaps are mounted as volumes, the updated connection string will automatically be available to the pods without any manual restarts. You can check the pods using get pods -l app=web-app'.
kubectl get pods -l app=web-app
4. Confirm Application Functionality:
- Verify that the web application is now using the updated database connection by performing relevant actions within the application, such as querying data or performing other operations.


問題 #86

Task
Create a new Ingress resource as follows:
. Name: echo
. Namespace : sound-repeater
. Exposing Service echoserver-service on
http://example.org/echo
using Service port 8080
The availability of Service
echoserver-service can be checked
i
using the following command, which should return 200 :
[candidate@cka000024] $ curl -o /de v/null -s -w "%{http_code} "
http://example.org/echo

答案：

解題說明：
Task Summary
Create an Ingress named echo in the sound-repeater namespace that:
* Routes requests to /echo on host example.org
* Forwards traffic to service echoserver-service
* Uses service port 8080
* Verification should return HTTP 200 using curl
# Step-by-Step Answer
1## SSH into the correct node
As shown in the image:
bash
CopyEdit
ssh cka000024
## Skipping this will result in a ZERO score!
2## Verify the namespace and service
Ensure the sound-repeater namespace and echoserver-service exist:
kubectl get svc -n sound-repeater
Look for:
echoserver-service ClusterIP ... 8080/TCP
3## Create the Ingress manifest
Create a YAML file: echo-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: echo
namespace: sound-repeater
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- host: example.org
http:
paths:
- path: /echo
pathType: Prefix
backend:
service:
name: echoserver-service
port:
number: 8080
4## Apply the Ingress resource
kubectl apply -f echo-ingress.yaml
5## Test with curl as instructed
Use the exact verification command:
curl -o /dev/null -s -w "%{http_code} "
http://example.org/echo
# You should see:
200
# Final Answer Summary
ssh cka000024
kubectl get svc -n sound-repeater
# Create the Ingress YAML
cat <<EOF > echo-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: echo
namespace: sound-repeater
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- host: example.org
http:
paths:
- path: /echo
pathType: Prefix
backend:
service:
name: echoserver-service
port:
number: 8080
EOF
kubectl apply -f echo-ingress.yaml
curl -o /dev/null -s -w "%{http_code} "
http://example.org/echo
