여러분 안녕하세요,
몇 시간 동안 이 문제로 막혀 있어서, 작동하는 해결책을 찾지 못해 도움을 요청합니다.
웹 서비스를 호스팅하는 여러 컨테이너가 있기 때문에, 트래픽을 올바른 컨테이너로 프록시하기 위해 자체 Nginx를 호스팅해야 합니다. (이것이 작동하지 않을 경우 Discourse를 별도 서버로 옮기는 것도 가능하지만, 이는 최후의 수단입니다.)
현재 다음 구성을 사용하고 있습니다:
- Nginx-Proxy - jwilder/nginx-proxy - Docker Image
- Nginx-Proxy/Acme-companion - GitHub - nginx-proxy/acme-companion: Automated ACME SSL certificate generation for nginx-proxy · GitHub
이 구성이 어떻게 결합되는지 보여주는 좋은 다이어그램은 다음 페이지에서 찾을 수 있습니다:
다음 튜토리얼을 활용했는데 도움이 되었지만, 여전히 성공하지 못했습니다.
- How to Install Multiple Discourse Forums on the Same Server
- Use Nginx-Proxy and LetsEncrypt Companion to Host Multiple Websites - Singular Aspect
찾아본 이전 Discourse 스레드(2년 이상 된 것들)에는 다음이 포함됩니다:
제 discourse app.yml 파일에는 다음 내용이 포함되어 있습니다(도메인과 이메일은 비공개 처리됨):
docker_args:
- "--net nginx-proxy"
VIRTUAL_HOST: {domain}
VIRTUAL_PORT: 80
LETSENCRYPT_HOST: {domain}
LETSENCRYPT_EMAIL: {email address}
아래 예시에서 노출된 포트는 주석 처리했습니다. 여러 변형을 시도했고, 다양한 제출물을 확인했습니다. 예를 들어, 이 게시물의 댓글: Discourse with jwilder/nginx-proxy howtos? , 또는 다른 곳에서 주석 처리되어 docker 변수로 VIRTUAL_PORT로 지정된 것을 보았습니다. 이 부분에 대해 약간 혼란스럽습니다.
#expose:
# - "80"
모든 컨테이너는 동일한 네트워크, 예를 들어
docker network inspect nginx-proxy

여기서 볼 수 있듯이 내 인증서는 성공적으로 생성되었지만, 현재 502 오류를 받고 있습니다.
discourse 컨테이너에서 nginx 로그를 확인하여 디버깅을 시도했지만, 로그 파일은 생성되지만 로그 내용이 채워지지 않습니다:

누군가 이 구성을 작동시킨 경험이 있는지, 또는 제가 받는 502 오류를 디버깅하는 방법에 대한 아이디어가 있는지 궁금합니다. 오류가 여러 변수에 의해 발생할 수 있다는 것은 알지만, 제 자신과 유사한 설정을 구성할 때 이 문제를 겪어본 분의 해결책이 도움이 될 수 있을 것입니다.
감사합니다.
