GCP VM Resize

VM의 머신 타입을 변경하여 스케일업/다운합니다.

사용법

/gcp-vm-resize                     # VM 목록 → 선택
/gcp-vm-resize my-vm               # 현재 스펙 확인 → 추천
/gcp-vm-resize my-vm e2-medium     # 직접 지정

Workflow

1. 현재 VM 스펙 확인

gcloud compute instances describe VM_NAME --zone=ZONE \
  --format="table(name,machineType.basename(),scheduling.preemptible,disks[0].diskSizeGb)"

2. 사용 가능한 머신 타입 조회

# 해당 Zone의 머신 타입 목록
gcloud compute machine-types list --zones=ZONE \
  --format="table(name,guestCpus,memoryMb,description)" \
  --filter="name~'^e2-|^n2-|^n1-'"

3. VM 중지 (필수)

gcloud compute instances stop VM_NAME --zone=ZONE

4. 머신 타입 변경

gcloud compute instances set-machine-type VM_NAME \
  --zone=ZONE \
  --machine-type=NEW_MACHINE_TYPE

5. VM 재시작

gcloud compute instances start VM_NAME --zone=ZONE

머신 타입 추천

E2 시리즈 (가성비, 범용)

타입	vCPU	메모리	용도
e2-micro	0.25	1GB	테스트, 경량
e2-small	0.5	2GB	개발
e2-medium	1	4GB	소규모 앱
e2-standard-2	2	8GB	일반 워크로드
e2-standard-4	4	16GB	중규모 앱
e2-standard-8	8	32GB	대규모 앱

N2 시리즈 (고성능)

타입	vCPU	메모리	용도
n2-standard-2	2	8GB	프로덕션
n2-standard-4	4	16GB	고부하
n2-highmem-4	4	32GB	메모리 집약
n2-highcpu-4	4	4GB	CPU 집약

커스텀 머신

# vCPU 4개, 메모리 10GB
gcloud compute instances set-machine-type VM_NAME \
  --zone=ZONE \
  --custom-cpu=4 \
  --custom-memory=10GB

출력 형식

## VM 리사이즈 결과

| 항목 | 이전 | 이후 |
|------|------|------|
| 머신 타입 | e2-micro | e2-medium |
| vCPU | 0.25 | 1 |
| 메모리 | 1GB | 4GB |
| 예상 월 비용 | ~$6 | ~$25 |

---
VM이 재시작되었습니다.

비용 비교 (asia-northeast3, 월 기준)

타입	온디맨드	Spot (80% 할인)
e2-micro	~$6	~$1.2
e2-small	~$12	~$2.4
e2-medium	~$25	~$5
e2-standard-2	~$50	~$10
e2-standard-4	~$100	~$20

주의사항

VM 중지 필수 (다운타임 발생)
디스크 크기는 별도 조정 (gcloud compute disks resize)
GPU 추가 시 N1 시리즈만 가능
Spot/Preemptible VM은 타입 변경 후에도 유지
