A. kubect1 get pods -o wide
kubectl delete po "nginx-dev" kubectl delete po "nginx-prod"
B. kubect1 get pods -o wide

정답：A

질문 # 54
For this item, you will have to ssh to the nodes ik8s-master-0 and ik8s-node-0 and complete all tasks on these nodes. Ensure that you return to the base node (hostname: node-1) when you have completed this item.
Context
As an administrator of a small development team, you have been asked to set up a Kubernetes cluster to test the viability of a new application.
Task You must use kubeadm to perform this task. Any kubeadm invocations will require the use of the --ignore-preflight-errors=all option.
Configure the node ik8s-master-O as a master node. .
Join the node ik8s-node-o to the cluster.

정답：

설명：
solution
You must use the kubeadm configuration file located at /etc/kubeadm.conf when initializing your cluster.
You may use any CNI plugin to complete this task, but if you don't have your favourite CNI plugin's manifest URL at hand, Calico is one popular option: https://docs.projectcalico.org/v3.14/manifests/calico.yaml Docker is already installed on both nodes and apt has been configured so that you can install the required tools.

질문 # 55
You are managing a Kubernetes cluster with a very specific RBAC setup.
- Users in the "engineering" group can create Pods in the "dev" namespace, but only if the Pod's name starts with "frontend".
- Users in the "security" group can view events in the "prod" namespace, but only if the event's reason is "Failed".
Create a YAML file to define a custom resource and define its permissions for the "engineering" and "security" groups.

정답：

설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 Create the "dev" and "prod" namespaces:
kubectl create namespace dev
kubectl create namespace prod
2. Define a Custom Resource Definition (CRD) for "pod-events":

3. Define the "engineering-pod-creation" role:

4. Create the "engineering-pod-creation" role binding:

5. Define the "security-event-view" role:

6. Create the "security-event-view" role binding:

7. Apply the YAML file to the cluster: kubectl apply -f rbac-config.yaml

질문 # 56
Score: 7%

Task
Reconfigure the existing deployment front-end and add a port specification named http exposing port 80/tcp of the existing container nginx.
Create a new service named front-end-svc exposing the container port http.
Configure the new service to also expose the individual Pods via a NodePort on the nodes on which they are scheduled.

정답：

설명：
Solution:
kubectl get deploy front-end
kubectl edit deploy front-end -o yaml
#port specification named http
#service.yaml
apiVersion: v1
kind: Service
metadata:
name: front-end-svc
labels:
app: nginx
spec:
ports:
- port: 80
protocol: tcp
name: http
selector:
app: nginx
type: NodePort
# kubectl create -f service.yaml
# kubectl get svc
# port specification named http
kubectl expose deployment front-end --name=front-end-svc --port=80 --tarport=80 --type=NodePort
