Set up file and image uploads to S3

위 링크의 첫 번째 게시글인
https://meta.discourse.org/t/set-up-file-and-image-uploads-to-s3
은 여전히 유효한 가이드이며, 관리자가 이를 따라 설정할 수 있는 상태인가요? 만약 그렇지 않다면, 2024년 현재 정확한 S3 가이드가 어디에 위치해 있는지 알려주시면 감사하겠습니다. 해당 가이드가 공식적이고 Discourse 팀의 지원을 받는다고 합니다.

위 가이드대로 구현했는데, 이미지는 S3에 업로드되고는 있지만 Discourse 인스턴스에서 깨져 보입니다.

우리의 설정 과정

  1. 위 가이드에 따라 S3 버킷 자체와 정책을 S3에 설정 (모든 단계를 정확히 준수)

  2. 위 가이드에 따라 app.yml 및 관리자 화면에서 env 설정 (동일하게 설정)

  3. launcher로 앱 재빌드

  4. CDN은 전혀 사용하지 않음 (CDN은 선택 사항이며 CDN 없이도 작동해야 한다고 이해했기 때문)

결과:

  1. Discourse가 이미지를 버킷에 업로드함
  2. 게시글 내 링크가 Discourse에 의해 amazon 링크로 올바르게 대체됨 (예: xxx-bucket.s3.dualstack.us-east-1.amazonaws.com/original/1X/a1b21eb5de071799d4b5e5215619d11d28602dfe.jpeg)
  3. 링크가 접근 불가 (공식 가이드의 S3 정책 때문으로 추정)

공식 가이드의 S3 정책에 대한 추정 변경 사항. Principal: 이 정책은 Principal을 지정하지 않으므로, 올바른 권한으로 인증된 사용자에게 적용됩니다. 익명(공개) 접근을 허용하려면 "Principal": "*"를 지정해야 합니다. 하지만 이는 버킷을 공개 상태로 만들 수 있어 좋은 해결책이 아닐 수도 있습니다.
이는 추정이며, 2024년 기준 가이드가 올바르게 업데이트되기를 바랍니다.

안녕하세요,
우리는 S3 스토리지로 Cloudflare R2를 사용 중입니다(현재는 정상 작동 중) 그리고 Discourse를 다른 서버로 이전하려 합니다.
그러나 “백업 업로드” 옵션을 체크한 상태에서도 백업에서 복원할 때 프로필 사진이 누락되었습니다.

그래서 여전히 로컬에 남아 있는 이미지를 이전하기 위해 기존 서버에서 s3 migrate 명령을 실행했는데, 아래 트레이스로 실패하고 있으며 원인이 명확하지 않습니다.

rake uploads:migrate_to_s3 --trace
** Invoke uploads:migrate_to_s3 (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute uploads:migrate_to_s3
Please note that migrating to S3 is currently not reversible!

제 추측으로는 S3 설정을 변경하셨고, 누락된 이미지들이 새 이미지들과 다른 버킷이나 다른 경로에 있는 것 같습니다.

다음 코드를 확인해 보면

 Upload.pluck(:url)

문제가 무엇인지 알 수 있을지도 모릅니다.

최근에도 동일한 문제를 겪었으며, 이 역할을 사용하여 iam 권한을 업데이트함으로써 문제를 해결할 수 있었습니다.

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
               "s3:List*",
               "s3:Get*",
               "s3:AbortMultipartUpload",
               "s3:DeleteObject",
               "s3:PutObject",
               "s3:PutObjectAcl",
               "s3:PutObjectVersionAcl",
               "s3:PutLifecycleConfiguration",
               "s3:CreateBucket",
               "s3:PutBucketCORS"
      ],
      "Resource": [
        "arn:aws:s3:::my-bucket",
        "arn:aws:s3:::my-bucket/*"
      ]
    },
    {
       "Effect": "Allow",
       "Action": [
           "s3:ListAllMyBuckets",
           "s3:ListBucket"
       ],
       "Resource": "*"
    }
  ]
}

또한 ACL 객체 소유권을 활성화해야 했습니다.

s3를 검색할 때의 전체 구성은 다음과 같습니다.

위 설정과 함께 멀티파트 업로드를 위해 버킷에 CORS를 설정하세요.

[
    {
        "AllowedHeaders": [
            "content-type",
            "x-amz-acl",
            "x-amz-meta-sha1-checksum"
        ],
        "AllowedMethods": [
            "GET",
            "HEAD",
            "PUT"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": [],
        "MaxAgeSeconds": 3000
    }

S3 서비스 제공업체를 변경할 수 있을까요?

이미 업로드된 이미지의 문제는 무시하고, S3 서비스 제공업체를 변경하려고 할 때 문제가 발생할지 알고 싶습니다. 사이트가 아직 운영 중이 아니라서 이 부분에 대해 큰 문제는 없습니다. 아직 개발 단계에 있기 때문입니다.

이미지를 로컬에 저장한 후, 새로운 서비스 제공업체를 다시 S3로 활성화할 수 있을까요?

273

rails에서 siteSettings.include_s3_uploads_in_backups=true로 설정한 뒤 백업을 생성하고, S3 설정을 변경한 다음 백업을 복구할 수 있습니다.

링크된 스레드에는 migrate_from_s3 태스크를 제거하는 PR이 언급되어 있으며, 이후 다시 추가되었다고 믿을 만한 근거를 찾지 못했지만, 이것이 여전히 유효한지 확인하고 싶었습니다. 저는 MinIO로 마이그레이션을 고려하고 있으며, 이를 의존성으로 만드는 것에 대해 약간 우려하고 있습니다.

이것이 위에서 언급한 문제에 대한 우회책이 될 수 있는지 궁금합니다. 해당 설정을 포함하고, 백업을 만들고, S3 설정을 비활성화한 후 백업을 복원하는 방식입니다.

276

네. 새 서버로 복원하겠습니다. 그렇게 하면 문제가 생겨도 여전히 작동하는 서버를 유지할 수 있습니다.

277

이 스레드를 보면, 이 설정이 S3에서 개별 파일을 다운로드하는 것 같은데, 게시물에서 로컬 파일이 아닌 S3 URL을 참조하는 경우 문제가 생길 수 있을 것 같습니다. 데이터베이스에서 이것이 어떻게 처리되는지 정확히 모르겠습니다. @Rhod 님이 다른 프로바이더로 마이그레이션한 것이 성공적이었는지 궁금합니다.

무사히 이전을 마쳤습니다. 이미지나 백업 파일의 수가 적어서 큰 문제가 없었습니다. 이 포럼은 아직 “운영” 단계가 아니라 테스트 목적으로만 사용되고 있었거든요.

결국 여러 번 시행착오를 거친 후, 최종적으로 마음에 들었던 서버(Hetzner)에 포럼을 다시 설치하고 백업과 이미지용으로 Cloudflare S3 R2(이전에는 Amazon S3를 사용했었습니다)를 설정했습니다.

큰 도움이 되지 못해서 죄송합니다. 나중에 다른 서버에서 테스트를 해볼 수 있을지 알아보겠습니다.

CF R2를 사용하면서 채팅 섬네일이 정상적으로 작동합니까?

그 오류를 눈치채지 못했어요. 사실 제 사이트에서는 채팅이 비활성화되어 있습니다.

사용하지 않을 것 같지만, 게시물에서 언급하신 것과 동일한 오류가 여전히 발생합니다.

와尔特, 감사합니다! 같은 내용을 올리려고 했는데, 이미 작성해 주셨네요.

@Discourse 와尔特의 게시물 내용을 첫 번째 게시물에 통합할 수 있을까요?

S3에 영상을 업로드할 수 있을까요? 현재 영상을 업로드하면 영상 썸네일만 S3에 업로드되고, 영상 본체는 업로드되지 않습니다.
