問題 #32
Configure a secret
Configure a secret in the math project with the following requirements: The name of the secret is: magic The secret defines a key with name: decoder_ring The secret defines the key with value:
XpWy9KdcP3Tr9FFHGQgZgVRCKukQdrQsbcl0c2ZYhDk=
答案：
解題說明：
See the solution below in Explanation.
Explanation:
Solution:
$ oc project math
$ oc create secret generic magic --from-literal key=decoder_ring --from- literal value=XpWy9KdcP3Tr9FFHGQgZgVRCKukQdrQsbcl0c2ZYhDk=
$ oc get secret -n math
問題 #33
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.
答案：
解題說明：
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.
問題 #34

2 full cores
The maximum number of replication controllers does not exceed 3 The maximum number of pods does not exceed 3 The maximum number of services does not exceed 6
答案：
解題說明：
See the solution below in Explanation.

spec:
capacity:
storage: 1Gi
accessModes:
- ReadOnlyMany
nfs:
path: /open001
server: 192.168.2.2
