RedHat Red Hat Certified Specialist in OpenShift Automation and Integration 認定 EX380 試験問題 (Q10-Q15):

質問 # 10
GitOps and MachineConfig - Push MachineConfig to Git

正解：

解説：
See the solution below in Explanation:
Explanation:
Step 1: Make sure the MachineConfig YAML has already been created or modified in the local Git repository.
This Task assumes the file change is ready to be committed.
Step 2: Run the command:
git commit -am "Add MachineConfig for motd" & & git push origin main
Step 3: Verify the commit succeeds and the push goes to the main branch.
The lab output shows:
[main 8d32a1] Add MachineConfig for motd
Detailed explanation:
This Task is part of a GitOps workflow. Instead of manually applying changes directly to the cluster, the desired configuration is stored in Git, and a GitOps controller such as Argo CD synchronizes the cluster to match the repository state. The command commits all tracked modified files with the message Add MachineConfig for motd and then pushes the change to the main branch. In this model, Git becomes the source of truth. A MachineConfig is typically used to manage node-level operating system configuration in OpenShift, so pushing it through GitOps ensures the change is auditable, repeatable, and reconciled declaratively. If the commit does not include the intended YAML, the synchronization mechanism will not apply the desired change.


質問 # 11
Spread replicas using podAntiAffinity
Task Information : Configure payments/api to prefer scheduling pods on different nodes.

正解：

解説：
See the solution below in Explanation:
Explanation:
* Patch deployment with preferred podAntiAffinity
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"affinity":{
* "podAntiAffinity":{
* "preferredDuringSchedulingIgnoredDuringExecution":[{
* "weight":100,
* "podAffinityTerm":{
* "labelSelector":{"matchLabels":{"app":"api"}},
* "topologyKey":"kubernetes.io/hostname"
* }
* }]
* }
* }}}}
* }'
* Encourages spread across nodes to reduce single-node impact.
* Verify spread
* oc -n payments get pods -o wide


質問 # 12
Deploy Event Router and capture Kubernetes events in logging
Task Information : Deploy an event router so Kubernetes events are recorded as logs, then trigger events and confirm they appear in logging queries.

正解：

解説：
See the solution below in Explanation:
* Deploy event router resources
* Apply a deployment/serviceaccount/rolebinding manifest for eventrouter:
* oc apply -f eventrouter.yaml -n openshift-logging
* Eventrouter watches event API and writes them to stdout (collected by logging).
* Verify eventrouter pod is running
* oc -n openshift-logging get pods | grep -i event
* Trigger some events
* oc -n default run evtest --image=busybox --restart=Never -- sleep 1
* oc -n default delete pod evtest
* Creation/deletion generates events.
* Query logs for events
* In the logging UI/backend, search for the namespace/pod name evtest or eventrouter messages.
* Explanation: Validates that events are being converted to searchable logs.


質問 # 13
Export and import a Kubernetes application (YAML export)
Task Information : Export typical app objects from orders and apply them into a new namespace orders- copy.

正解：

解説：
See the solution below in Explanation:
Explanation:
* Export objects to YAML
* oc -n orders get deploy,svc,route,cm,secret -o yaml > orders-app.yaml
* Exports key application resources.
* Create target namespace
* oc new-project orders-copy
* Apply exported YAML
* oc -n orders-copy apply -f orders-app.yaml
* Recreates resources (some fields may need adjustment, like namespaces or immutable fields).
* Validate
* oc -n orders-copy get all


質問 # 14
Add a second Identity Provider (HTPasswd) alongside LDAP
Task Information : Configure multiple identity providers by adding an HTPasswd IDP without removing the existing LDAP IDP.

正解：

解説：
See the solution below in Explanation:
Explanation:
* Create a local htpasswd file with a test user
* htpasswd -c -B -b /tmp/htpass.txt testuser RedHat123!
* -c creates a new file (use only once).
* -B uses bcrypt hashing (recommended).
* -b supplies password non-interactively (good for labs).
* Create the HTPasswd secret in openshift-config
* oc -n openshift-config create secret generic htpass-secret --from-file=htpasswd=/tmp/htpass.txt
* OAuth reads the htpasswd key from this secret.
* Edit OAuth and add the HTPasswd provider (keep LDAP intact)
* oc edit oauth cluster
Add another entry under spec.identityProviders:
- name: local-htpasswd
mappingMethod: claim
type: HTPasswd
htpasswd:
fileData:
name: htpass-secret
* This adds a second login option while preserving LDAP.
* Restart OAuth pods
* oc -n openshift-authentication delete pod -l app=oauth-openshift
* Ensures the updated list of identity providers is loaded.
* Verify login works for htpasswd user
* Log in via console using testuser.
* Confirm the user is created:
* oc get user testuser
