带有外部 nginx 和 omnibus 的 gitlab docker 注册表

Question

我已经运行一个 docker 容器内的 gitlab 服务器和另一个 docker 容器内的外部 nginx 服务器，因此 gitlab nginx 服务器已停用。现在我想使用 gitlab 服务器中包含的 docker 注册表。

我尝试从管理手册中获取信息：https://docs.gitlab.com/ee/administration/container_registry.html

并使用来自链接文件的合适的 nginx 配置： https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/support/nginx/registry-ssl

我在 gitlab.rb 中添加了：

... 
registry_external_url 'url'
registry_nginx['enable'] = false
registry['enable'] = true
...

但是如果我尝试登录（docker 登录 url），我只会收到 502 Bad Gateway 错误。我还尝试了一些其他的组合配置，但总是得到同样的错误。有人让它工作吗？我需要向 omnibus 文件添加更多设置，还是仍然无法将 gitlab 内部 docker 注册表与 omnibus 和外部 nginx 一起使用？

我也遇到了和你一样的问题，并通过以下方式解决了它：

Nginx:

    proxy_pass          http://localhost:5000;
  }
}

gitlab.rb

registry_external_url 'https://registry.project-oc.de'
registry_nginx['listen_port'] = 5000
gitlab_rails['registry_enabled'] = true
registry_nginx['enable'] = false
registry['enable'] = true

编辑这两个文件后，您必须重新启动 nginx 和 gitlab

好的，我成功了。

 }

}

也许 Andrioshe 的 nginx 配置也可以，但我在尝试时做了一些更改并与其他配置混合。我认为普通 docker-regsitry 的配置文件也可以使用...将来会尝试。

不过更重要的是gitlab omnibus的配置。

registry_external_url 'https://sub.domain.tld'
registry['registry_http_addr'] = "<ip_of_gitlab_docker_container>:<port_of_gitlab_container>"
registry_nginx['enable'] = false
registry['enable'] = true

It is important to set the 'regsitry_http_addr' to the gitlab docker registry ip and port instead of localhost.

Answer 3

我从 docker 更新 Gitlab 后遇到了同样的问题。

刚刚通过添加修复：

gitlab_rails['registry_enabled'] = true
registry_nginx['enable'] = false
registry['enable'] = true

Answer 4

上面的答案很好，但不太适合我的设置，因此我将在此处添加我的配置，以便对某些人有所帮助。我正在运行使用 compose Docker 构建官方 GitLab Docker 图像，并且我已经将 Traefik v2 设置为反向代理。这些设置取自 official GitLab Omnibus settings.

在docker-compose.yml的gitlab.rb环境变量部分：

gitlab_rails['registry_enabled'] = true
registry['enable'] = true
registry_external_url 'https://registry.example.com'
registry_nginx['listen_port'] = 80
registry_nginx['listen_https'] = false"

然后在docker-compose.yml中添加如下标签：

- "traefik.http.routers.gitlab-registry.rule=Host(`registry.example.com`)"
- "traefik.http.routers.gitlab-registry.tls=true"
- "traefik.http.routers.gitlab-registry.entrypoints=websecure"
- "traefik.http.routers.gitlab-registry.service=gitlab-registry-service"
- "traefik.http.services.gitlab-registry-service.loadbalancer.server.port=80"

这些设置应该适用于注册表的相同域或不同域。 nginx 服务器运行注册中心被告知运行通过端口 80 上的纯 http，这使得与 Traefik 集成变得非常容易。
