질문 # 27
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 # 28
Create a PV and PVC
Task information Details:
Create a PersistentVolume named landing-pv with 1Gi , ReadOnlyMany , NFS backend, and Retain reclaim policy.
Create a PersistentVolumeClaim named landing-pvc requesting 1Gi , ReadOnlyMany , and storage class nfs2 .
정답：
설명：
See the solution below in Explanation.
Explanation:
Solution:
* Create landing-pv.yaml:
apiVersion: v1
kind: PersistentVolume
metadata:
name: landing-pv
spec:
capacity:
storage: 1Gi
accessModes:
- ReadOnlyMany
nfs:
path: /open001
server: 192.168.2.2
persistentVolumeReclaimPolicy: Retain
* Apply it:
oc apply -f landing-pv.yaml
* Create landing-pvc.yaml:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: landing-pvc
spec:
accessModes:
- ReadOnlyMany
resources:
requests:
storage: 1Gi
storageClassName: nfs2
* Apply it:
oc apply -f landing-pvc.yaml
* Verify:
oc get pv
oc get pvc
oc describe pv landing-pv
oc describe pvc landing-pvc
This task validates persistent storage provisioning and claim binding concepts.
질문 # 29
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 # 30
Manage Cluster Project and Permission
Task information Details:
Create projects apollo , test , and demo .
Grant bob the cluster-admin role.
Prevent ordinary authenticated users from self-provisioning projects.
Allow john to create projects.
Give natasha view-only access to test and apollo .
Give armstrong admin access to apollo .
Remove the kubeadmin user secret.
정답：
설명：
See the solution below in Explanation.
Explanation:
Solution:
* Create the projects:
oc new-project apollo
oc new-project test
oc new-project demo
* Grant cluster-admin to bob:
oc adm policy add-cluster-role-to-user cluster-admin bob
* Disable normal self-provisioning for authenticated users:
oc adm policy remove-cluster-role-from-group self-provisioner system:authenticated:oauth
* Allow john to self-provision:
oc adm policy add-cluster-role-to-user self-provisioner john
* Give natasha view access in test and apollo:
oc policy add-role-to-user view natasha -n test
oc policy add-role-to-user view natasha -n apollo
* Give armstrong admin in apollo:
oc policy add-role-to-user admin armstrong -n apollo
* Remove kubeadmin secret:
oc delete secret kubeadmin -n kube-system
* Verify permissions:
oc adm policy who-can create projectrequests
oc describe rolebinding.rbac -n apollo
oc describe rolebinding.rbac -n test
This task tests core OpenShift administration around project lifecycle control, cluster-level RBAC, and decommissioning default bootstrap credentials.
