StartVM and TerminateVM Main Flow of Cloud Drivers - cloud-barista/cb-spider GitHub Wiki
StartVM()/TerminateVM() retry timeout 조정 이력
[Init]
- StartVM: 30s
- TerminateVM: 10s
- issues:
- Alibaba TerminateVM 시 오류 발생
- OpenStack StartVM 시 오류 발생
[2021.05.21.]
- StartVM: 120s
- TerminateVM: 60s
[StartVM main flow]
- Focusing on CallLog and Waiting Loop
- Waiting Loop: VM 정보 제공을 위해서 VM 정보가 생성될 때까지(=running status) 기다리는 작업
- StartVM 규격 참고: StartVM(vmReqInfo VMReqInfo) (VMInfo, error)
- Flow에서 함수 이름은 실제 이름과 다를 수 있음
- SetUser('cb-user'): cloud-init 데이터 설정
- CreateUser('cb-user'): runSSH into VM

[TerminateVM main flow]
- Focusing on CallLog and Waiting Loop
- Waiting Loop: VM이 원하는 상태로 될 때까지 기다리는 작업
- TerminateVM 규격 참고: TerminateVM(vmIID IID) (VMStatus, error)
- Flow에서 함수 이름은 실제 이름과 다를 수 있음
