amazon-s3 - “500 Internal Server Error” 在 minio 上有作业工件

Question

我正在使用 min.io 作为本地 S3 服务在本地运行 gitlab-ce。 CI/CD 缓存工作正常，与 S3 兼容 minio 的基本连接良好。 (版本: gitlab-ce:13.9.2-ce.0 、 gitlab-runner:v13.9.0 和 minio/minio:latest 当前 c253244b6fb0 。)
是否有额外的配置来区分作业工件和管道工件并将它们存储在本地 S3 兼容的对象存储中？
在我的测试仓库中，“构建”阶段构建了一个稀疏的 R 包。当我使用本地 gitlab 作业工件时，它成功并进入“测试”和“部署”阶段，没有问题。 (这适用于 S3 存储的缓存，尽管该配置仅在 gitlab-runner 内。)现在我已将 minio 配置为工件的本地 S3 兼容对象存储，但它失败了。

唯一的失败是在工件存储尝试中。 (使用 gitlab 中的工件，这一切都成功并奏效了。)
我在 minio 日志中找不到“无效参数”的引用(在此期间什么也没说)。我不确定这是一个小问题。
gitlab 配置的相关部分:

gitlab_rails['object_store']['enabled'] = true
gitlab_rails['object_store']['proxy_download'] = false
gitlab_rails['object_store']['connection'] = {
  'provider' => 'AWS',
  'host' => "minio.mydomain.com",
  # 'region' => '',
  'aws_access_key_id' => '<AWS_ACCESS_KEY_ID>',
  'aws_secret_access_key' => '<AWS_SECRET_ACCESS_KEY>',
  'path_style' => true
}
gitlab_rails['object_store']['objects']['artifacts']['bucket'] = 'gitlab-artifacts-storage'
gitlab_rails['object_store']['objects']['external_diffs']['enabled'] = false
gitlab_rails['object_store']['objects']['lfs']['enabled'] = false
gitlab_rails['object_store']['objects']['uploads']['bucket'] = 'gitlab-uploads-storage'
gitlab_rails['object_store']['objects']['packages']['enabled'] = false
gitlab_rails['object_store']['objects']['dependency_proxy']['enabled'] = false
gitlab_rails['object_store']['objects']['terraform_state']['enabled'] = false
gitlab_rails['object_store']['objects']['pages']['enabled'] = false

该配置改编自 https://docs.gitlab.com/ee/administration/object_storage.html ，取消选择我认为不需要的组件的存储。我加了 'path_style' => true因为没有它，默认为 bucket.minio.mydomain.com没有正确解析(所以这主要是与 S3 兼容的，而不是完美的 AWS)。我也用 'proxy_download' 试过这个真实的，没有变化。
我登录到 minio 控制台，并且 gitlab-artifacts-storage桶存在。事实上，在这些失败的“构建”测试之后，我看到这个存储桶中存储了新创建的作业工件(如 job.log )，所以我知道基本连接(即访问 key 和 secret )有效:

在我的研究中，我看到了与 nginx rev-proxy 问题相关的类似错误，这表明 traefik 配置中的某些内容(或只是它的存在)可能是一个问题。它只是传递流量，不进行路径转换/剥离。无论如何，所有关于 rev-proxy 的讨论都在 nginx 上进行，经常尝试进行某种路径调整，并通过对 nginx 配置进行一些看似无关的更改来解决。我还没有找到任何映射到 traefik 域的映射。
traefik 访问.log

我知道作业工件和管道工件之间存在差异，所以我认为我缺少的是“作业”和“管道”之间的配置区别。
.gitlab-ci.yml 片段

(是的，它既是缓存又是工件。这是我测试 CI 子系统的一个实例，不是我打算维护的东西。)
这是在 traefik 后面的 docker-swarm 中反向代理(和 SSL 终止符)。

Answer 1

答案是绕过空字符串测试；底层协议(protocol)不支持无区域配置，也没有配置选项来支持它。
这个技巧之所以能够奏效，是因为使用了 'endpoint'导致 'region'被忽略。有了这个，将区域设置为某物并强制端点允许它工作:

gitlab_rails['object_store']['connection'] = {
  'provider' => 'AWS',
  'host' => "minio.mydomain.com",
  'region' => 'us-east-1',                      # this must be non-empty, but is ignored ...
  'endpoint' => 'https://minio.mydomain.com',   # ... because of 'endpoint'
  'aws_access_key_id' => '<AWS_ACCESS_KEY_ID>',
  'aws_secret_access_key' => '<AWS_SECRET_ACCESS_KEY>',
  'path_style' => true
}

(我欠弗洛里安的发现，在 gitlab-org/gitlab#297227 中。)
