SIMULATIONScale an application automaticallyAutomatically scale the hydra application deployment configuration in the lerna project with the following requirements:Minimum number of replicas: 6 Maximum number of replicas: 9Target average CPU utilization: 60 percent Container CPU resource request: 25m Container CPU resource limit: 100m
Answer(s): A
Solution:$ oc project lerna$ oc get pods$ oc get all | grep deployment$ oc autoscale deployment.apps/hydra --max=9 --min=6 --cpu-percent=60$ oc get hpa$ oc set resources deployment.apps/hydra --limits=cpu=100m -- requests=cpu=25m$ oc describe deployment.apps/hydra | grep Limits -A3
SIMULATIONConfigure a secure routeConfigure the oxcart application in the area51 project with the following requirements:The application uses a route called oxcartThe application uses a CA signed certificate with the following subject fields:/C=US/ST=NV/L=Hiko/O=CIA/OU=USAF/CN=classified.apps.domainxx.example.com The application is reachable only at the following address: https://classified.apps.domainxx.example.comThe application produces outputA utility script called newcert has been provided to create the CA signed certificate. You may enter the certificate parameters manually or pass the subject as a parameter.Your certificate signing request will be uploaded to the CA where it will immediately be signed and then downloaded to your current directory.
Solution:$ oc project area51$ oc get pods$ oc get all | grep deployment$ oc get route$ oc delete route oxcart$ openssl genrsa -out ex280.key 2048$ openssl req -new -key ex280.key -out ex280.csr -subj "/C=US/ST=NV/L=Hiko/O=CIA/OU=USAF/CN=classified.apps.domainxx.example.com"$ openssl x509 -req -in ex280.csr -signkey ex280.key -out ex280.crt$ oc create route edge oxcart --service oxcart --key ex280.key --cert ex280.crt --hostname classified.apps.domainxx.example.com$ oc get route$ oc get svc
SIMULATIONConfigure a secretConfigure a secret in the math project with the following requirements: The name of the secret is: magicThe secret defines a key with name: decoder_ring The secret defines the key with value:XpWy9KdcP3Tr9FFHGQgZgVRCKukQdrQsbcl0c2ZYhDk=
Solution:$ oc project math$ oc create secret generic magic --from-literal key=decoder_ring --from- literal value=XpWy9KdcP3Tr9FFHGQgZgVRCKukQdrQsbcl0c2ZYhDk=$ oc get secret -n math
SIMULATIONConfigure an application to use a secretConfigure 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_RINGThe 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

SIMULATIONTask 1Manage Identity ProviderTask 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.
Solution:Create the initial HTPasswd file with the first user:htpasswd -c -B -b /tmp/htpass.txt bob indionceAdd the remaining users:htpasswd -b /tmp/htpass.txt qwerty catalog htpasswd -b /tmp/htpass.txt john john123htpasswd -b /tmp/htpass.txt armstrong natasha123htpasswd -b /tmp/htpass.txt natasha arthstrong htpasswd -b /tmp/htpass.txt harry harry123htpasswd -b /tmp/htpass.txt susan susuan123Create the secret in openshift-config:oc create secret generic ex280-secure --from-file=htpasswd=/tmp/htpass.txt -n openshift-configEdit OAuth and add the HTPasswd identity provider:oc edit oauth clusterUse a valid structure like this:spec:identityProviders:- name: ex280-idp-secure mappingMethod: claim type: HTPasswd htpasswd:fileData:name: ex280-secureSave and exit.Restart OAuth pods:oc delete pod -n openshift-authentication -l app=oauth-openshiftVerify:oc get pods -n openshift-authentication oc get oauth cluster -o yamlThis task validates OpenShift local authentication configuration through HTPasswd and cluster OAuth integration.
SIMULATIONTask 2Manage Cluster Project and PermissionTask 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.
Solution:Create the projects:oc new-project apollo oc new-project test oc new-project demoGrant cluster-admin to bob:oc adm policy add-cluster-role-to-user cluster-admin bobDisable normal self-provisioning for authenticated users:oc adm policy remove-cluster-role-from-group self-provisioner system:authenticated:oauthAllow john to self-provision:oc adm policy add-cluster-role-to-user self-provisioner johnGive 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 apolloGive armstrong admin in apollo:oc policy add-role-to-user admin armstrong -n apolloRemove kubeadmin secret:oc delete secret kubeadmin -n kube-systemVerify permissions:oc adm policy who-can create projectrequests oc describe rolebinding.rbac -n apollo oc describe rolebinding.rbac -n testThis task tests core OpenShift administration around project lifecycle control, cluster-level RBAC, and decommissioning default bootstrap credentials.
