SIMULATION
use the Trivy to scan the following images,
1. amazonlinux:1
2. k8s.gcr.io/kube-controller-manager:v1.18.6

正解：A
質問 # 66
You can switch the cluster/configuration context using the following command: [desk@cli] $ kubectl config use-context qa Context: A pod fails to run because of an incorrectly specified ServiceAccount Task: Create a new service account named backend-qa in an existing namespace qa, which must not have access to any secret. Edit the frontend pod yaml to use backend-qa service account Note: You can find the frontend pod yaml at /home/cert_masters/frontend-pod.yaml
正解：
解説：
[desk@cli] $ k create sa backend-qa -n qa sa/backend-qa created [desk@cli] $ k get role,rolebinding -n qa No resources found in qa namespace. [desk@cli] $ k create role backend -n qa --resource pods,namespaces,configmaps --verb list # No access to secret [desk@cli] $ k create rolebinding backend -n qa --role backend --serviceaccount qa:backend-qa [desk@cli] $ vim /home/cert_masters/frontend-pod.yaml apiVersion: v1 kind: Pod metadata:

質問 # 67
Your Kubernetes cluster is running a set of microservices that are deployed in separate namespaces. You want to ensure that a specific microservice in the 'web-app' namespace can only communicate with services in the 'api-gateway' namespace. How can you implement this using NetworkPolicies?
正解：
解説：
Solution (Step by Step) :
1. Identify Targeted Services: Determine the specific microservice in the 'web-app' namespace that needs restricted access. Let's assume it's named 'web-service'
2 Create Network Policy: Create a NetworkPolicy YAML file named 'web-service-access-yamr to define the allowed communication:
- This policy allows the 'web-services pods in the 'web-app' namespace to communicate With services in the sapi-gateways namespace. 3. Apply Network Policy: Apply the NetworkPolicy using ' kubectr' bash kubectl apply -f web-service-access-yaml 4. Verify Network Policy: Verify that the NetworkPolicy is applied: bash kubectl get networkpolicies -n web-app 5. Test Access: Test communication from the 'web-service pods in the 'web-apps namespace to services in the 'api-gateway' namespace. This communication should be allowed. Try communicating from the 'web-service' pods to services in other namespaces. This communication should be blocked. This NetworkPolicy restricts the 'web-services pods to only communicate with services in the 'api-gateway' namespace. This effectively enforces a specific communication pattern between microservices deployed in different namespaces.
質問 # 68
A container image scanner is set up on the cluster.
Given an incomplete configuration in the directory
/etc/kubernetes/confcontrol and a functional container image scanner with HTTPS endpoint https://test-server.local.8081/image_policy
正解：A
解説：
2. Validate the control configuration and change it to implicit deny.
Finally, test the configuration by deploying the pod having the image tag as latest.
質問 # 69
You are using a container image signed by a trusted entity. Describe the steps involved in verifying the signature of the image during the image pull process in Kubernetes.
正解：
解説：
Solution (Step by Step) :
1. Generate the Signature:
- The trusted entity uses a signing key and algorithm to create a signature for the container image.
- The signature is typically stored as a separate file or within a manifest file associated with the image.
2. Configure the Kubernetes Cluster:
- Enable the 'ImageSignatureVerification' feature gate in your Kubernetes cluster. This feature gate enables the cluster to verity image signatures-
- Configure the 'ImageP01icyWebh00k' to point to a custom webnook server that will handle the signature verification process.
3. Implement the Webhook Server:
- Create a custom webhook server that will be responsible for verifying the image signature.
- This server will:
- Receive tne image manifest and signature from Kubernetes.
- Validate the signature using the trusted entity's public key.
- Return a success or failure status to Kubernetes based on the verification outcome.
4. Pull the Signed Image:
- When you pull the signed image from the registry, Kubernetes will:
- Fetch the image manifest and signature.
- Send them to the 'ImagePolicyWebhooR for verification.
- If the webhook returns a success status, the image will be allowed to run.
- If the webhook returns a failure status, the image will be rejected.
5. Example Implementation:
- You can use tools like 'cosign' or 'sigstores to generate and verify image signatures.
- Implement the webhook server using a programming language like Go or Python.
# Example using cosign to verify a signature cosign verify -key
- This command will use the provided public key to verify the signature of the specified image.
6. Security Considerations:
- Ensure that the webhook server is secure and only accessible to authorized Kubernetes components.
- Use robust authentication and authorization mechanisms for the webh00k server.
- Consider implementing rate limiting to protect against potential denial-of-service attacks.
