이것은 간헐적으로 발생합니다. 몇 시간 후에 저장소를 사용하지 않으면 "504 Gateway Time-out"을 다시 발견하고 해결하기 위해 swarm 노드와 nexus 컨테이너에 로그인하고 다시 말려 야합니다. 504 오류에 대한 해결책을 찾도록 도와주세요. 컨테이너가 동일한 호스트에서 실행 중이며 오버레이 네트워크가 사용되지 않은 경우이 문제는 존재하지 않습니다.
이 문제를 해결할 수있는 해결책이 있습니까? – simdrouin
오픈 스택 업그레이드로 문제가 사라졌습니다. 더 이상 버전 정보 나 설정 정보가 없어서 더 자세한 정보를 제공 할 수 없습니다. – Anu
