質問 # 12
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
正解：
解説：
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
質問 # 13
Create a CronJob test-cron
Task information Details:
Create service account jupiter .
Grant anyuid SCC and cluster- admin to it.
Update CronJob cron-test to use that service account.
正解：
解説：
See the solution below in Explanation.
Explanation:
Solution:
* Switch to the project hosting the cronjob, if needed:
oc project cron-test
* Create the service account:
oc create sa jupiter
* Grant anyuid:
oc adm policy add-scc-to-user anyuid -z jupiter -n cron-test
* Grant cluster-admin:
oc adm policy add-cluster-role-to-user cluster-admin system:serviceaccount:cron-test:jupiter
* Update the cronjob:
oc patch cronjob cron-test -p '{"spec":{"jobTemplate":{"spec":{"template":{"spec":{"serviceAccountName":" jupiter"}}}}}}'
* Verify:
oc get cronjob cron-test -o yaml | grep serviceAccountName
Notes:
* The uploaded lab uses oc set sa cronjob.batch/cron-test jupiter, which is not the usual command form for CronJobs. Patching the pod template is the reliable method.
This task checks service account and privilege adjustments for scheduled workloads.
質問 # 14

Solution:
* Switch to the quart project:
oc project quart
* Create the secure route:
oc create route edge htquart \
--service=httpd \
--hostname=quart.apps.ocp4.example.com \
--cert=./req.crt \
--key=./req.key
* Verify:
oc get route htquart
oc describe route htquart
* Test resolution and access if DNS is available:
curl -k https://quart.apps.ocp4.example.com
This task checks route exposure, TLS termination, and secure ingress administration.
