SIMULATION
Task 5
Create LimitRanges for Project Darpa
Task information Details:
Switch to project darpa and create a LimitRange with Pod and Container minimums and maximums of CPU and memory, plus default container values.
Solution:
Switch to the target project:
oc project darpa
Create a YAML file, for example limitrange.yaml:
apiVersion: v1
kind: LimitRange
metadata:
name: darpa-limits
namespace: darpa
spec:
limits:
- type: Pod
max:
cpu: 300m
memory: 300Mi
min:
cpu: 5m
memory: 5Mi
- type: Container
max:
cpu: 300m
memory: 300Mi
min:
cpu: 5m
memory: 5Mi
default:
cpu: 100m
memory: 100Mi
Apply it:
oc apply -f limitrange.yaml
Verify:
oc get limitrange -n darpa
oc describe limitrange darpa-limits -n darpa
This task validates namespace-level defaulting and constraint policies for pod scheduling and resource consumption.
SIMULATION
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.
Solution:
$ oc get all | grep deploy
$ oc set env --from=secret/magic deployment.apps/qed
SIMULATION
Task 18
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.
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.
SIMULATION
Task 9
Use Secret in Monday Project
Task information Details:
Use the secret created earlier as environment variables in deployment monday.
Solution:
Switch to the correct project if needed:
oc project monday
Inject environment variables from the secret:
oc set env deployment/monday --from=secret/magic
Verify:
oc set env deployment/monday --list
oc describe deployment monday
Notes:
The uploaded lab references secret/file-secret, but Task 8 clearly intends the secret to be named magic.
In a real exam, match the actual secret name present in the cluster.
This task tests secret consumption by workloads through environment variable injection.
SIMULATION
Deploy an application
Deploy the application called oranges in the apples project so that the following conditions are true:
The application uses the ex280sa service account
No additional configuration components have been added or removed The application produces output
