feat: 사용자 본인 컨테이너 재시작 API 추가 - #481
Conversation
관리자를 거치지 않고 본인 컨테이너를 재시작할 수 있도록
POST /api/requests/{requestId}/reboot 를 추가했다.
재시작은 현재 노드를 후보로 고정한 마이그레이션(same_node=true)으로 구현한다.
config-server의 /migrate는 새 Pod를 만들어 정상 확인한 뒤에야 기존 Pod를 지우므로,
삭제 후 재생성 방식과 달리 중간에 실패해도 사용자의 기존 컨테이너가 그대로 살아있다.
- Status에 REBOOTING 추가. 재시작 중에도 자원을 점유하므로 activeStatuses에 포함해
"내 승인 완료 신청" 조회로 진행 상태를 폴링할 수 있게 했다.
- 실제 처리는 approveRequest와 같은 방식으로 전용 executor에 넘기고 즉시
REBOOTING 상태를 응답한다. 일반 사용자 요청이 몰려도 관리자 승인 처리량이
굶지 않도록 approvalExecutor와 분리된 rebootExecutor를 사용한다.
- 마이그레이션 호출 실패 시 기존 Pod는 그대로이므로 상태만 FULFILLED로 되돌리고,
결과 DB 반영에 실패하면 실제 인프라와 어긋나므로 REBOOTING을 유지한 채 알림만 보낸다.
- 10분 넘게 REBOOTING에 갇힌 요청은 기존 재조정 스케줄러가 관리자에게 알린다.

config-server가 새 Pod는 정상 생성했지만 기존 Pod 정리에 실패하면 노드에 Pod가 남아 자원을 계속 점유한다. 마이그레이션 경로와 동일하게 관리자 알림을 보내도록 했다. 정리 거부 사유 메시지도 마이그레이션뿐 아니라 승인/재시작 진행 중인 경우를 포함하도록 문구를 맞췄다.

Do not restore FULFILLED after an ambiguous /migrate failure.
PodService.migratePod maps transport and timeout failures to BusinessException. This catch cannot distinguish a pre-side-effect failure from a completed replacement whose response was lost. Skipping applyMigratedPodInfo then leaves podName and pod_external_ports stale, while revertToFulfilled allows another reboot. Keep REBOOTING and use the existing manual-reconciliation alert.

Make the request mock stateful across the reboot lifecycle.
The synchronous executor runs processReboot() before rebootPod() returns. Because getStatus() always returns REBOOTING and beginReboot()/endReboot() do not change it, the response assertion passes even if response mapping occurs before beginReboot() or after endReboot(). Initialize shared status as FULFILLED, then stub beginReboot() to set REBOOTING and endReboot() to set FULFILLED. This makes the test detect incorrect response ordering in the public reboot lifecycle.

재시작마다 config-server가 컨테이너 파일시스템 전체를 NFS에 다시 tar로 떠서 저장하므로, 연타로 인한 반복 실행을 막기 위해 마지막 재시작으로부터 10분 이내에는 재시도를 거부한다. 성공/실패 마무리 단계에서 Request를 다시 읽을 때 findById 대신 findByIdForUpdate를 사용해, 그 사이 다른 작업이 상태를 바꾼 경우를 approveRequest와 동일한 방식으로 방어한다.

Do not start the cooldown before task acceptance.
lastRebootedAt is set before rebootExecutor.execute. If the executor rejects the task, revertToFulfilled() only calls endReboot() and retains this timestamp. The user then receives POD_REBOOT_COOLDOWN for 10 minutes even though no reboot task ran. Clear or restore the timestamp on submission rejection, or record it only after task acceptance.

일단 보류합니다. 이미지 커밋 기반 재시작이 실제로 패키지를 보존하려면 save_image.sh가 필요한데, 확인해보니 그 스크립트가 실제 base 이미지에 없어서 지금까지 관리자 마이그레이션도 커밋 없이 base 이미지로 재생성되고 있었습니다. pod에 docker.sock이 없어 컨테이너가 스스로를 커밋할 수도 없고, 호스트 레벨 SSH 커밋 방식(farm SSH 60초 타임아웃 초과 문제 포함)으로 재설계가 필요해서 별도로 진행하겠습니다. 재개 조건은 develop README에 기록해뒀습니다. |

배경
일반 사용자가 컨테이너에 문제가 생겼을 때 관리자에게 요청하지 않고 직접 재시작할 수 있어야 한다는 요구가 있었습니다.
구현 방식
단순 삭제 후 재생성 방식은 생성이 실패하면 사용자가 컨테이너 없이 남게 됩니다. 대신 현재 노드를 후보로 고정한 마이그레이션(
same_node=true)으로 구현했습니다. config-server의/migrate는 새 Pod를 만들어 정상 동작을 확인한 뒤에야 기존 Pod를 지우므로, 중간에 실패해도 사용자의 기존 컨테이너가 그대로 살아있습니다.변경 사항
API
POST /api/requests/{requestId}/reboot— 본인 소유 + FULFILLED 상태인 신청만 재시작. 즉시status=REBOOTING인 신청 정보(SaveRequestResponseDTO)를 200으로 반환합니다.GET /api/requests/my/approved의status가REBOOTING→FULFILLED로 돌아오는지로 확인합니다. 별도 폴링 API는 추가하지 않았습니다.상태
Status에REBOOTING추가. 재시작 중에도 자원을 점유하므로activeStatuses()에 포함했습니다 — 빠뜨리면 재시작 도중 사용자 목록에서 본인 컨테이너가 사라집니다.Request.delete(), 사용자 정리(AdminUserService), 중복 username 검사도MIGRATING과 동일하게REBOOTING을 막습니다.비동기 처리
approveRequest와 같은 패턴으로 전용 executor에 넘기고 즉시 응답합니다.approvalExecutor와 분리된rebootExecutor(pool 2, 큐 없음, AbortPolicy)를 씁니다. 일반 사용자가 아무 때나 누르는 요청이라 같은 풀을 쓰면 재시작이 몰렸을 때 관리자 승인 처리까지 함께 막힙니다.실패 처리
REBOOTING을 유지해 재시도를 막고 관리자 알림만 보냅니다(기존 마이그레이션과 동일한 판단).REBOOTING에 갇힌 요청은 기존 재조정 스케줄러가 관리자에게 알립니다.에러 코드 추가
