質問 # 45
Scale the deployment from 5 replicas to 20 replicas and verify
正解：
解説：
kubectl scale deploy webapp --replicas=20 kubectl get deploy webapp kubectl get po -l app=webapp
質問 # 46
You are deploying a service in Kubernetes that needs to access a database service running in a different namespace. How can you configure NetworkPolicy to allow communication between these services across namespaces?
正解：
解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Create a NetworkPolicy in the service's namespace:
- Create a NetworkPolicy in the namespace of the service that needs to access the database.
- Code:
2. Ensure the Database Namespace has the Correct Label: - Ensure that the namespace where the database service is running has the label 'database: true'. 3. Apply the NetworkPolicy: - Apply the NetworkPolicy using 'kubectl apply -f networkpolicy.yaml'.
質問 # 47
You are deploying a microservices application on Kubernetes where each service has its own dedicated namespace. You want to implement a robust network security policy that allows communication between specific services only. How can you achieve this using NetworkPolicies?
正解：
解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Network Policies for Each Service:
- For each service, create a NetworkPolicy that defines the allowed ingress and egress traffic.
- Example for service "service-A":
2. Apply Network Policies: - Apply the NetworkPolicies to the respective namespaces using 'kubectl apply -f networkpolicy.yaml'
質問 # 48
You are setting up a new Kubernetes cluster with a highly sensitive application that requires access control at the pod level. Explain how you can use NetworkPolicy to restrict access to pods within your cluster.
正解：
解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Create a NetworkPolicy Resource: Define a 'NetworkPolicy' resource using a YAML file. The
'NetworkPolicy' resource will contain the rules for network traffic access to the pods. You can use 'kubectl create -f networkpolicy.yaml' to create the NetworkPolicy resource.
2. Set 'podSelectoo: Use the podSelector' field to identify the pods that will be affected by the policy. In this example, we are targeting pods with the label 'app: sensitive-app'. 3. Define 'ingress' and 'egress' Rules: Use the 'ingress' and 'egress' sections to define the rules for incoming and outgoing traffic. 'ingress': This section specifies which pods or services are allowed to send traffic to the pods targeted by the 'NetworkPolicy'. Here, we are allowing traffic from pods labeled app: trusted-service'. 'egress': This section specifies which destinations the pods targeted by the NetworkPolicy are allowed to send traffic to. In this example, we are allowing egress traffic to the IP address range 10.0.0.0/16. 4. Implement the "NetworkPolicy': Apply the YAML file using 'kubectl apply -f networkpolicy.yaml'. Once applied, the NetworkPolicy will be enforced, blocking any traffic that does not meet the specified rules.
質問 # 49
Watch the job that runs 10 times one by one and verify 10 pods are created and delete those after it's completed
正解：
解説：
kubectl get job -w kubectl get po kubectl delete job hello-job
