Let's Encrypt 자동 갱신 및 IPv6

제품 지원
1

음, IPv6 문제와 Let’s Encrypt 관련 내용은 정말 모호했습니다.

Discourse를 다시 구축했을 때는 모든 것이 정상적으로 작동했고, 새로운 인증서가 발급되었습니다.

하지만 자동 Let’s Encrypt는 작동하지 않았습니다. 사이트가 IPv6을 통해 도달할 수 없었기 때문에(실행 중) Let’s Encrypt가 .well-known 폴더를 검증하는 데 타임아웃이 발생했습니다.

Docker 호스트 설치도 확인해 보았는데, IPv4의 경우와 달리 Docker 내부 네트워크로 전달하는 ip6table 포워더가 없었습니다. 하지만 ip6tables에서는 모든 것이 허용되어 있었습니다 …

Docker 호스트 설정에서 IPv6을 활성화하고 데몬을 재시작해 보았지만, 이것도 도움이 되지 않았습니다.

조지, 감사합니다. 첫 번째 질문인데, discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub 문서에 따라 진행하셨는지 확인해 주시겠습니까?

방금 IPv6가 활성화된 우리 Digital Ocean ‘셀프 호스팅’ 테스트 사이트 중 하나를 확인해 보니, SSL 인증서가 문제없이 갱신된 것을 확인할 수 있었습니다.

네, 우리가 따진 방식이 바로 그거예요. discourse-setup을 실행하기 전에 먼저 docker를 수동으로 설치했거든요.

그걸 한 지 좀 됐어요(2년 반쯤). 처음에는 아무 문제없이 잘 작동했지만, 1년 후에 IPv6용 AAAA 레코드를 추가했는데, 그때부터 자동 갱신이 멈췄어요. 그래서 SSL 인증서를 새로 받으려면 매번 discourse rebuild를 실행해야 했죠.

자동 갱신이 실패한 시점의 로그가 있나요? 있다면 매우 도움이 될 것입니다.

또한, 공식 가이드에서 어떤 부분이라도 벗어나서 설정하셨나요? 추가적인 리버스 프록시? app.yml 수동 수정? 호스트 시스템의 방화벽 설정? 등등.

의심을 한다는 뜻은 아니지만, IPv6를 사용하는 수천 개의 셀프호스트드 인스톨레이션이 존재하는 상황에서, IPv6 사이트의 SSL 인증서 갱신이 실패하고 있다면 상당한 불만이 쏟아졌을 것이라고 생각합니다.

공식 가이드를 아주 엄격하게 따랐습니다 — 추가 설정은 전혀 하지 않았으며, 프록시도 전혀 사용하지 않았습니다. Ubuntu와 Docker만 설치된 맨 처음 상태의 VPS입니다.

VPS에는 IPv6가 활성화되어 있었지만, 말씀드린 것처럼 AAAA 레코드를 DNS에 추가한 시점은 훨씬 이후였습니다.
서버에서 IPv6 관련 다른 특정 설정은 입력하지 않았습니다.

SSL 갱신 실패에 대한 상세 로그는 다음과 같습니다:
