kubenetes 관련 명령어

 

✅ 연동된 전체 context 목록 확인

kubectl config get-contexts

 

🔥 삭제 순서 (context + 클러스터 + 사용자)

아래 순서대로 하나씩 실행하면 완전히 삭제 가능해:

✅ 1. context 삭제

kubectl config delete-context gke_kubenetes-test-445100_asia-northeast3-a_lecture-cluster
kubectl config delete-context gke_kubenetes-test-445100_us-central1-c_lecture-cluster

 

✅ 2. cluster 삭제

 

kubectl config delete-cluster gke_kubenetes-test-445100_asia-northeast3-a_lecture-cluster
kubectl config delete-cluster gke_kubenetes-test-445100_us-central1-c_lecture-cluster

 

✅ 3. user(authinfo) 삭제

kubectl config delete-user gke_kubenetes-test-445100_asia-northeast3-a_lecture-cluster
kubectl config delete-user gke_kubenetes-test-445100_us-central1-c_lecture-cluster

 

 

 

💻 노드관련

아래 순서대로 하나씩 실행하면 노드 추가 

✅ 1. 추가할 container 확인하기

gcloud container clusters list

NAME             LOCATION     MASTER_VERSION      MASTER_IP     MACHINE_TYPE   NODE_VERSION        NUM_NODES  STATUS
lecture-cluster  us-central1  1.31.6-gke.1020000  ********      e2-standard-2  1.31.6-gke.1020000  1          RUNNING

 

✅ 2. 추가할 container 확인하기

kubectl get nodes

NAME                                              STATUS   ROLES    AGE   VERSION
gke-lecture-cluster-default-pool-xxx              Ready    <none>   12h   v1.31.6-gke.1020000
gke-lecture-cluster-default-pool-yyy              Ready    <none>   5m    v1.31.6-gke.1020000

 

 

✅ 3. CPU/Memory 점유율 요약

kubectl top nodes

NAME                                       CPU(cores)   CPU%   MEMORY(bytes)   MEMORY%
gke-lecture-cluster-default-pool-xxx       250m         12%    700Mi           10%

 

 

🎬 재시작

✅ 1. 클러스터  리스타트
