name: nginx
spec:
nodeSelector:
gpu: true
yaml
//Verify
kubectl get no -show-labels
kubectl get po
kubectl describe po nginx | grep Node-Selectors
B. kubectl run nginx --image=nginx --restart=Always --dry-run -o

質問 # 50
You have a deployment named 'redis-deployment' running a Redis server with 3 replicas. You need to configure a service with the 'NodePort' type to expose Redis on all nodes in the cluster, but restrict access only from specific pods within a namespace.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a NetworkPolicy:
- Define a NetworkPolicy resource that allows traffic from specific pods in a namespace to the Redis service.

2. Create the NodePort service: - Create a NodePort service for the Redis deployment, allowing access to the Redis server through all nodes in the cluster.

3. Apply the resources: - Apply the NetworkPolicy and service using 'kubectl apply -f networkpolicy.yaml' and 'kubectl apply -f redis- service.yamP. 4. Verify: - Check the status of the NetworkPolicy and service: - 'kubectl get networkpolicies allow-specific-pods-to-redis -n - 'kubectl get services redis-service -n 5. Test: - From a pod labeled with 'app: allowed-app', try to connect to the Redis service using the NodePort on the node. - From a pod that doesn't have the 'allowed-app' label, attempt to connect to the Redis service using the NodePort. You should not be able to connect. Note: Replace with the actual namespace where your Redis deployment and the pods allowed to access it are located.

質問 # 51
Get list of all the pods showing name and namespace with a jsonpath expression.

正解：

解説：
kubectl get pods -o=jsonpath="{.items[*]['metadata.name'
, 'metadata.namespace']}"
