NEW QUESTION # 25
You are deploying a new application named 'streaming-services that requires 7 replicas. You want to implement a rolling update strategy that allows for a maximum of two pods to be unavailable at any given time. However, you need to ensure that the update process is triggered automatically whenever a new image is pusned to the Docker Hub repository 'streaming/streaming-service:latest'.
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Update the Deployment YAMI-:
- Update the 'replicas' to 7.
- Define 'maxunavailable: 2" and 'maxSurge: (Y in the 'strategy.rollingUpdate' section.
- Configure a 'strategy.types to 'Rollingl_lpdates to trigger a rolling update when the deployment is updated.
- Add a 'spec-template.spec.imagePullPolicy: Always' to ensure that the new image is pulled even if it exists in the pod's local cache.
2. Create the Deployment: - Apply the updated YAML file using 'kubectl apply -f streaming-service-deployment-yamr 3. Verify the Deployment - Check the status of the deployment using 'kubectl get deployments streaming-service-deployment to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'streaming/streaming-service:latest' Docker Hub repository. 5. Monitor the Deployment - Use 'kubectl get pods -l app=streaming-service' to monitor the pod updates during the rolling update process. You will observe that two pods are terminated at a time, while two new with the updated image are created. 6. Check for Successful Update: - Once the deployment is complete, use 'kubectl describe deployment streaming-service-deployment' to see that the 'updatedReplicas' field matches the 'replicas' field, indicating a successful update.
NEW QUESTION # 26
Refer to Exhibit.
Task
You are required to create a pod that requests a certain amount of CPU and memory, so it gets scheduled to-a node that has those resources available.
* Create a pod named nginx-resources in the pod-resources namespace that requests a minimum of 200m CPU and 1Gi memory for its container
* The pod should use the nginx image
* The pod-resources namespace has already been created
Answer:
Explanation:
Solution:
NEW QUESTION # 27
Context
You are asked to set resource requests and limits for a running workload to ensure fair resource management.
"Do not delete the existing Deployment . Failure to do so will result in a reduced score." Next, ensure that the total amount of resources in the namespace matches the maximum resources the Pods from the nginx-resources Deployment can request.
Failure to do so will result in the updated Deployment failing to roll out successfully.
Answer:
Explanation:
See the Explanation below for complete solution.
Explanation:
Below are the exact steps/commands you can run.
1) Locate the Deployment and its namespace
kubectl get deploy -A | grep nginx-resources
You should see output like:
<namespace> nginx-resources ...
Set a variable (replace <NS> with what you see):
NS=<NS>
Confirm replicas:
kubectl -n $NS get deploy nginx-resources -o jsonpath='{.spec.replicas}{"\n"}'
2) Check if there is a ResourceQuota in that namespace
kubectl -n $NS get resourcequota
kubectl -n $NS describe resourcequota
If there is a quota, note these fields (common ones):
* requests.cpu
* requests.memory
* limits.cpu
* limits.memory
3) Decide requests/limits for the Deployment (example values)
If the question (in your environment) provides specific values, use those.
If it doesn't, a typical safe pair is:
* requests: cpu: 100m, memory: 128Mi
* limits: cpu: 200m, memory: 256Mi
I'll proceed with these example values. If your lab specifies different numbers, just swap them in.
4) Update the existing Deployment (DO NOT DELETE)
Option A (fastest): kubectl set resources
Assuming the container name is the first container (we'll detect it):
kubectl -n $NS get deploy nginx-resources -o jsonpath='{.spec.template.spec.containers[*].name}{"\n"}' If it prints a single container name, set it like this:
kubectl -n $NS set resources deploy nginx-resources \
--requests=cpu=100m,memory=128Mi \
--limits=cpu=200m,memory=256Mi
Verify the Deployment now has resources
kubectl -n $NS get deploy nginx-resources -o jsonpath='{.spec.template.spec.containers[0].resources}{"\n"}'
5) Compute the total resources requested by the Deployment
Get replicas:
REPLICAS=$(kubectl -n $NS get deploy nginx-resources -o jsonpath='{.spec.replicas}') echo $REPLICAS
6) Ensure the namespace quota matches (or exceeds) those totals
This is the part the question warns about: if the quota is too low, the Deployment update will fail to roll out.
6.1 If a ResourceQuota already exists
Patch it to allow at least the totals you calculated.
First, identify quota name:
RQ=$(kubectl -n $NS get resourcequota -o jsonpath='{.items[0].metadata.name}') echo $RQ Then patch (example: replicas=2 # requests.cpu=200m, requests.memory=256Mi):
kubectl -n $NS patch resourcequota $RQ --type='merge' -p '{
"spec": {
"hard": {
"requests.cpu": "200m",
"requests.memory": "256Mi",
"limits.cpu": "400m",
"limits.memory": "512Mi"
}
}
}'
Adjust those numbers to your replicas × request, and replicas × limit (if your quota also enforces limits).
6.2 If there is NO ResourceQuota
Create one that matches the Deployment max request totals.
Example for replicas=2 with our sample requests/limits:
cat <<EOF | kubectl apply -n $NS -f -
apiVersion: v1
kind: ResourceQuota
metadata:
name: nginx-resources-quota
spec:
hard:
requests.cpu: "200m"
requests.memory: "256Mi"
limits.cpu: "400m"
limits.memory: "512Mi"
EOF
7) Verify rollout succeeds
kubectl -n $NS rollout status deploy nginx-resources
kubectl -n $NS get pods
Verify the running pods actually have the requests/limits:
kubectl -n $NS get pod -l app=nginx-resources -o jsonpath='{range .items[*]}{.metadata.name}{" "}{.spec.
containers[0].resources}{"\n"}{end}'
(If the label selector app=nginx-resources doesn't exist, just pick a pod name from kubectl get pods and run:) kubectl -n $NS describe pod <pod-name> | sed -n '/Limits:/,/Requests:/p' Common reasons this fails (and the fix)
* Rollout stuck / pods pending with "exceeded quota"Check:
* kubectl -n $NS describe pod <pending-pod>
* kubectl -n $NS describe resourcequota
Fix: increase ResourceQuota hard values to match required totals.
* You set requests higher than quota allowsFix: either reduce requests or raise quota.
kubectl get deploy -A | grep nginx-resources
kubectl -n <NS> get deploy nginx-resources -o jsonpath='{.spec.replicas}{"\n"}{.spec.template.spec.
containers[0].name}{"\n"}'
kubectl -n <NS> describe resourcequota
NEW QUESTION # 28
You have a Kubernetes cluster with a Deployment named 'my-app' that runs a web application. You want to restrict access to this application to only specific users within your organization. How would you use Service Accounts and RBAC to implement this?
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Create a Service Account:
- Create a new Service Account specifically for your application:
- Apply this YAML file using 'kubectl apply -f my-app-sa.yaml'. 2. Create a Role: - Define a Role that grants specific permissions to the Service Account. For example, you might want to grant read access to the Deployment's secrets:
- Apply this YAML file using 'kubectl apply -f my-app-reader.yaml' 3. Bind the Role to the Service Account: - Create a RoleBinding that associates the 'my-app-reader' Role with the 'my-app-sa' Service Account:
- Apply this YAML file using 'kubectl apply -f my-app-sa-binding.yaml' 4. Update the Deployment: - Update the 'my-app' Deployment to use the new Service Account:
- Apply the updated Deployment configuration using 'kubectl apply -f my-app.yaml'. 5. Verify: - Ensure that pods within the 'my-app' Deployment are running with the correct Service Account. You can use 'kubectl get pods -l app=my-app -o wide' to inspect the pod details. 6. Restricting Access to Specific Users: - To restrict access to the application to specific users within your organization, you would need to: - Configure a more granular Role to grant specific access levels (e.g., read-only, edit, etc.). - Use a Kubernetes authentication provider (such as OAuth2 or OpenID Connect) to authenticate and authorize users. - Bind the Role to the user's identity, ensuring they have the appropriate permissions. Important Note: This example provides a basic setup for RBAC with Service Accounts. In real-world scenarios, you might need to configure more complex RBAC rules to address your specific security requirements and user access control policies.]
