No additional configuration components have been added or removed The application produces output
答案：
解題說明：
See the solution below in Explanation.
Explanation:
Solution:

$ oc set resources deployment.apps/atlas --resources=memory=80Mi
問題 #23
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 #24
Configure an application to use a secret
Configure the application called qed in the math project with the following requirements:
The application uses the secret previously created called: magic The secret defines an environment variable with name: DECODER_RING The application output no longer displays: Sorry, application is not configured correctly.
答案：
解題說明：
See the solution below in Explanation.
Explanation:
Solution:
$ oc get all | grep deploy
$ oc set env --from=secret/magic deployment.apps/qed
問題 #25
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.
答案：
解題說明：
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.
