Create Project Template
Task information Details:
Generate the bootstrap project template, create it in openshift-config , update the cluster project configuration to use the template, and create a new project to validate it.
Correct Answer:
See the solution below in Explanation.
Explanation:
Solution:
* Generate the default template:
oc adm create-bootstrap-project-template -o yaml > template.yaml
* Review and edit template.yaml if required.
* Create the template in openshift-config:
oc create -f template.yaml -n openshift-config
* Edit the cluster project configuration:
oc edit project.config.openshift.io/cluster
* Add or update:
spec:
projectRequestTemplate:
name: project-request
* Save and exit.
* Create a test project:
oc new-project test123
* Verify the template behavior:
oc get project test123 -o yaml
Notes:
* The uploaded lab text shows projects.config.openshift.io cluster-admin; the standard resource is project.
config.openshift.io/cluster.
This task checks cluster-wide customization of new-project creation behavior.
Autoscale of Pods
Task information Details:
Create an HPA for httpd with min=2 , max=9 , and CPU target 60% .
Set resource requests on the httpd deployment so autoscaling can function properly.
Correct Answer:
See the solution below in Explanation.
Explanation:
Solution:
* Set resource requests on the deployment:
oc set resources deployment httpd --requests=cpu=50m,memory=100Mi
* Create the HPA:
oc autoscale deployment httpd --min=2 --max=9 --cpu-percent=60
* Verify:
oc get hpa
oc describe hpa httpd
oc get deployment httpd -o yaml
Why resource requests matter:
* HPA CPU utilization is calculated against requested CPU.
* Without requests, percentage-based autoscaling is incomplete or invalid.
This task focuses on autoscaling prerequisites and policy creation.
Create Resource Quota for Project Rocky
Task information Details:
Use project rocky and create a quota named rocky-quota with limits for CPU, memory, pods, services, replication controllers, and secrets.
Correct Answer:
See the solution below in Explanation.
Explanation:
Solution:
* Ensure the project exists and switch to it:
oc new-project rocky
oc project rocky
* Create the quota:
oc create quota rocky-quota \
--hard=limits.cpu=2,limits.memory=1Gi,pods=3,services=6,replicationcontrollers=6,secrets=6
* Verify:
oc get resourcequota -n rocky
oc describe quota rocky-quota -n rocky
Notes:
* The lab text uses cpu=2,memory=1G and secret=6; in real OpenShift usage, the more reliable forms are limits.cpu, limits.memory, and secrets.
* If the exam specifically expects the exact resource names shown in the lab environment, use what the cluster accepts.
This task checks quota enforcement and namespace resource governance.

Configure a service account in the apples project to meet the following requirements:

Correct Answer:
See the solution below in Explanation.

Solution:
