問題 #30
Install Helm Chart
Task information Details:
Add the Helm repository do280-repo and install the example-app release from the specified chart.
答案：
解題說明：
See the solution below in Explanation.
Explanation:
Solution:
* Add the repository:
helm
repo add do280-repo http://helm.ocp4.example.com/charts
* Refresh repositories:
helm repo update
* Install the chart:
helm install example-app do280-repo/etherpad
* Verify:
helm list
oc get all
Notes:
* The uploaded lab text appears to spell the chart name incorrectly as ehterpad.
* In practice, use the actual chart name published in the repo. If the lab repo truly contains the typo, follow the repo index result.
This task tests Helm repository management and application deployment.
問題 #31
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.
答案：
解題說明：
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.
問題 #32
Create Secret with Name Magic in Math Project
Task information Details:
Create a secret named magic in the math project that stores MYSQL_ROOT_PASSWORD=redhat .
答案：
解題說明：
See the solution below in Explanation.
Explanation:
Solution:
* Switch to the math project:
oc project math
* Create the secret:
oc create secret generic magic --from-literal=MYSQL_ROOT_PASSWORD=redhat
* Verify:
oc get secret magic
oc describe secret magic
Note:
* The uploaded lab text contains a typo --from-listeral; the valid option is --from-literal.
* The output in the lab also appears inconsistent. The intended secret name is magic .
This task checks secret creation and secure configuration data handling.
