CKA &. CKAD (104) 썸네일형 리스트형 Practice Test - Labels and Selectors ㅁ We have deployed a number of PODs. They are labelled with 'tier', 'env' and 'bu'. How many PODs exist in the 'dev' environmnet? Use selectors to filter the output kubectl get pods --show-labels kubectl get pods --selector env=dev or kubectl get pods -l env=dev or kbuectl get pods -l env=dev --no-headers | wc -l ㅁ How many PODs are in the "finance" business unit ("bu")" kubectl get pods --selec..

Manual Scheduling ㅁ A pod definition file nginx.yaml is given. Create pod using the file. kubectl apply -f nginx.yaml ㅁ What is the status of the created POD? kubectl get pods ㅁ Why is the POD in a pending state? kubectl -n kube-system get pods kubectl describe pod nginx ㅁ Manually schedule the pod on node01 apiVersion: v1 kind: Pod metadata: name: nginx spec: nodeName: node01 containers: - image: nginx name: ngi.. kubectl apply command ㅁ Declarative Create Object kubectl apply -f nginx.yaml kubectl apply -f /path/to/config-files Update Object kubectl apply -f nginx.yaml Practice Test - Imperative Command ㅁ Deploy a pod named nginx-pod using the nginx:alpine image kubectl run nginx-pod --image=nginx:alpine ㅁ Deploy a redis pod using the redis:alpine image with the labels set to tier=db kubectl run redis --image=redis:alpine --label=tier-db ㅁ Create a service redis-service to expose the redis application within the cluster on port 6379 kubectl expose pod redis --name redis-service --port 6379 --ta.. CKA Tip 2: Imperative Command with kubectl [Pod] - Create an NGINX Pod kubectl run nginx --image=nginx - Generate POD Manifest YAML file (-o yaml). Don't create it(--dry-run) kubectl run nginx --image=nginx --dry-run=client -o yaml [Deployment] - create a deployment kubectl create deploymnet --iage=nginx nginx - Generate Deployment YAML file (-o yaml).
