NEW QUESTION # 49
You have a Kubernetes cluster witn multiple namespaces. One namespace, "dev", is used for development and testing purposes. You want to prevent pods in the "dev" namespace from accessing resources in other namespaces.
Answer:
Explanation:
Solution (Step by Step):
1. Apply Namespace-Level Network Policy: Create a network policy that restricts pods within the "dev" namespace from accessing any resources outside the namespace.
- Create a YAML file for the Network Policy:
2. Deploy the Network Policy: Apply the YAML file using ' kubectl apply -f networkpolicy.yamr Note: This policy allows pods within "dev" to communicate with each other but blocks communication with pods in other namespaces.
NEW QUESTION # 50
Context:
Cluster: prod
Master node: master1
Worker node: worker1
You can switch the cluster/configuration context using the following command:
[desk@cli] $ kubectl config use-context prod
Task:
Analyse and edit the given Dockerfile (based on the ubuntu:18:04 image)
/home/cert_masters/Dockerfile fixing two instructions present in the file being prominent security/best-practice issues.
Analyse and edit the given manifest file
/home/cert_masters/mydeployment.yaml fixing two fields present in the file being prominent security/best-practice issues.
Note: Don't add or remove configuration settings; only modify the existing configuration settings, so that two configuration settings each are no longer security/best-practice concerns.
Should you need an unprivileged user for any of the tasks, use user nobody with user id 65535
