질문 # 14
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.
정답：
설명：
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.
질문 # 15
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.
정답：
설명：
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.
질문 # 16
Manage Identity Provider
Task information Details:
Create the following HTPasswd users: bob, qwerty, john, armstrong, natasha, harry, susan .
Create a secret from the HTPasswd file in openshift-config .
Configure cluster OAuth to use the HTPasswd identity provider.
Restart the OAuth pods so the new authentication configuration takes effect.
정답：
설명：
See the solution below in Explanation.
Explanation:
Solution:
* Create the initial HTPasswd file with the first user:
htpasswd -c -B -b /tmp/htpass.txt bob indionce
* Add the remaining users:
htpasswd -b /tmp/htpass.txt qwerty catalog
htpasswd -b /tmp/htpass.txt john john123
htpasswd -b /tmp/htpass.txt armstrong natasha123
htpasswd -b /tmp/htpass.txt natasha arthstrong
htpasswd -b /tmp/htpass.txt harry harry123
htpasswd -b /tmp/htpass.txt susan susuan123
* Create the secret in openshift-config :
oc create secret generic ex280-secure --from-file=htpasswd=/tmp/htpass.txt -n openshift-config
* Edit OAuth and add the HTPasswd identity provider:
oc edit oauth cluster
* Use a valid structure like this:
spec:
identityProviders:
- name: ex280-idp-secure
mappingMethod: claim
type: HTPasswd
htpasswd:
fileData:
name: ex280-secure
* Save and exit.
* Restart OAuth pods:
oc delete pod -n openshift-authentication -l app=oauth-openshift
* Verify:
oc get pods -n openshift-authentication
oc get oauth cluster -o yaml
This task validates OpenShift local authentication configuration through HTPasswd and cluster OAuth integration.
질문 # 17
Install Helm Chart
Task information Details:
Add the Helm repository do280-repo and install the example-app release from the specified chart.
정답：
설명：
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.
질문 # 18
Configure limits
Configure your OpenShift cluster to use limits in the bluebook project with the following requirements:
The name of the LimitRange resource is: ex280-limits
The amount of memory consumed by a single pod is between 5Mi and 300Mi The amount of memory consumed by a single container is between 5Mi and
300Mi with a default request value of 100Mi
The amount of CPU consumed by a single pod is between 10m and 500m
The amount of CPU consumed by a single container is between 10m and 500m with a default request value of
100m
정답：
설명：
See the solution below in Explanation.
Explanation:
Solution:
$ vim limit.yaml
# Edit the yaml file like below mentioned
apiVersion: "v1" kind: "LimitRange" metadata:
name: "resource-limits" spec:
limits:
- type: "Pod"
max:
cpu: "500m" memory: "300Mi"
min:
cpu: "10m" memory: "5Mi"
- type: "Container" max:
cpu: "500m" memory: "300Mi"
min:
cpu: "10m" memory: "5Mi"
defaultRequest: cpu: "100m" memory: "100Mi"
$ oc create -f limit.yaml --save-config -n bluebook
$ oc describe limitranges -n bluebook
