NEW QUESTION # 12
Kubeconfig Management - Set Context in Kubeconfig
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
Step 1: Verify the cluster name, namespace, and user name that should be referenced.
The lab uses cluster api-ocp4-example-com:6443, namespace audit-ns, and user audit-sa.
Step 2: Run the command:
oc config set-context audit --cluster api-ocp4-example-com:6443 --namespace audit-ns --user audit-sa -- kubeconfig audit.config Step 3: Confirm context creation.
The lab output shows:
Context "audit" created.
Detailed explanation:
A kubeconfig context ties together three things: a cluster endpoint, a user identity, and optionally a default namespace. This Task creates a context named audit in the file audit.config. Contexts are useful because they simplify repeated administration by letting the user switch between prepared working environments instead of re-entering cluster and namespace details each time. The namespace portion is especially helpful for project- scoped operations, because commands run under that context default to the chosen namespace. Accuracy matters here: if the user name in the context does not match the credentials entry or the cluster name does not exist in the kubeconfig, the context will not function as intended.
NEW QUESTION # 13
Create and use a service account token via kubeconfig
Task Information : Create SA ci-bot in ci namespace and generate a kubeconfig that authenticates using its token.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Create namespace and service account
* oc new-project ci
* oc -n ci create sa ci-bot
* The SA will represent automation access.
* Grant permissions (example: edit in namespace)
* oc -n ci policy add-role-to-user edit system:serviceaccount:ci:ci-bot
* Without permissions, token auth succeeds but API actions are denied.
* Generate token (TokenRequest)
* TOKEN=$(oc -n ci create token ci-bot)
* OCP issues a short-lived token by default (good practice).
* Create kubeconfig using the token
* oc config set-cluster lab --server="$(oc whoami --show-server)" \
* --insecure-skip-tls-verify=true --kubeconfig=ci-bot.kubeconfig
* oc config set-credentials ci-bot --token="$TOKEN" --kubeconfig=ci-bot.kubeconfig
* oc config set-context ci --cluster=lab --user=ci-bot --namespace=ci \
* --kubeconfig=ci-bot.kubeconfig
* oc config use-context ci --kubeconfig=ci-bot.kubeconfig
* This produces a self-contained kubeconfig for CI automation.
* Test access
* oc --kubeconfig=ci-bot.kubeconfig get pods
NEW QUESTION # 14
Deploy Event Router and capture Kubernetes events in logging
Task Information : Deploy an event router so Kubernetes events are recorded as logs, then trigger events and confirm they appear in logging queries.
Answer:
Explanation:
See the solution below in Explanation:
* Deploy event router resources
* Apply a deployment/serviceaccount/rolebinding manifest for eventrouter:
* oc apply -f eventrouter.yaml -n openshift-logging
* Eventrouter watches event API and writes them to stdout (collected by logging).
* Verify eventrouter pod is running
* oc -n openshift-logging get pods | grep -i event
* Trigger some events
* oc -n default run evtest --image=busybox --restart=Never -- sleep 1
* oc -n default delete pod evtest
* Creation/deletion generates events.
* Query logs for events
* In the logging UI/backend, search for the namespace/pod name evtest or eventrouter messages.
* Explanation: Validates that events are being converted to searchable logs.
NEW QUESTION # 15
Create and use client certificates with kubeconfig (CSR flow)
Task Information : Generate a client key/CSR for audit2, approve it, extract the signed cert, and build a kubeconfig using that cert.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Generate private key and CSR
* openssl genrsa -out audit2.key 2048
* openssl req -new -key audit2.key -out audit2.csr -subj "/CN=audit2/O=auditors"
* CN becomes username; O can map to groups in some setups.
* Base64 encode CSR for the API object
* CSR=$(base64 -w0 audit2.csr)
* Kubernetes CSR object expects base64-encoded request data.
* Create the CSR object
* cat < < EOF | oc apply -f -
* apiVersion: certificates.k8s.io/v1
* kind: CertificateSigningRequest
* metadata:
* name: audit2-csr
* spec:
* request: ${CSR}
* signerName: kubernetes.io/kube-apiserver-client
* usages:
* - client auth
* EOF
* Approve the CSR
* oc adm certificate approve audit2-csr
* Approval triggers certificate issuance.
* Extract the signed certificate
* oc get csr audit2-csr -o jsonpath='{.status.certificate}' | base64 -d > audit2.crt
* Produces the client certificate file.
* Build kubeconfig using cert/key
* oc config set-credentials audit2 \
* --client-certificate=audit2.crt --client-key=audit2.key \
* --embed-certs=true --kubeconfig=audit2.kubeconfig
* oc config set-cluster lab \
* --server="$(oc whoami --show-server)" \
* --insecure-skip-tls-verify=true \
* --kubeconfig=audit2.kubeconfig
* oc config set-context audit2 \
* --cluster=lab --user=audit2 --namespace=default \
* --kubeconfig=audit2.kubeconfig
* Creates a kubeconfig that authenticates using client certificates.
* Test
* oc --kubeconfig=audit2.kubeconfig get ns
NEW QUESTION # 16
Recover a NotReady worker node (basic remediation workflow)
Task Information : Diagnose a NotReady worker node and restore it to Ready state using standard OpenShift admin workflow.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Identify failing node and status
* oc get nodes
* Confirms which node is NotReady.
* Inspect node conditions and events
* oc describe node < worker >
* Shows kubelet condition issues (network, disk pressure, runtime, etc.).
* Check MachineConfigPool state
* oc get mcp
* oc describe mcp worker
* If MCP is degraded, node may be stuck applying a config.
* Check node logs (kubelet)
* oc adm node-logs < worker > --path=kubelet.log
* Often reveals why node isn't reporting Ready.
* Remediate based on symptom
* Examples:
* If out of disk: free space, then verify kubelet recovers.
* If stuck MCO: investigate current/desired config and fix broken MachineConfig.
* If node cordoned/drained incorrectly: uncordon after remediation.
* oc adm uncordon < worker >
* Confirm node returns Ready
* oc get node < worker >
