gitlab docker 注册与外部 nginx 和综合

Question

我已经在 docker 容器内运行了一个 gitlab 服务器，在另一个 docker 容器内运行了一个外部 nginx 服务器，因此 gitlab nginx 服务器被停用。 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

并使用链接文件中的 nginx 配置： https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/support/nginx/registry-ssl

到 gitlab.rb 我添加了：

... 
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？ 我需要向综合文件添加更多设置，还是仍然无法将 gitlab 内部 884065722228588 注册表与综合和外部 nginx 一起使用？

好的，我搞定了。

 }

}

也许 Andrioshe 的 nginx 配置也有效，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。

但更重要的是gitlab综合配置。

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

将 'regsitry_http_addr' 设置为 gitlab docker 注册表 ip 和端口而不是 localhost 很重要。

我也有和你一样的问题，并让它与以下一起工作：

nginx：

  access_log  /var/log/nginx/gitlab_registry_access.log;
  error_log   /var/log/nginx/gitlab_registry_error.log;
}

server {

}

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

编辑完这两个文件后，您必须重新启动 nginx 和 gitlab

Answer 3

上面的答案很好，但不太适合我的设置，所以我会在这里添加我的配置，以便它可以帮助某人。 我正在使用 compose 运行官方 GitLab Docker 映像，并且已经将 Traefik v2 设置为反向代理。 这些设置取自官方 GitLab Omnibus 设置。

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 中添加以下标签：

- "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或单独域。 运行注册表的 nginx 服务器被告知在端口 80 上运行纯 http，这使得与 Traefik 集成非常容易。

Answer 4

从 docker 更新 Gitlab 后，我遇到了同样的问题。

刚刚通过添加修复：

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

Answer 5

问题可能是注册表端口仅绑定到 localhost.network 接口，这是默认设置。

将以下内容添加到 gitlab.rb

registry_external_url 'https://registry.gitlab.example.com'
gitlab_rails['registry_enabled'] = true

registry['enable'] = true
registry['username'] = "registry"
registry['group'] = "registry"
registry['dir'] = "/var/opt/gitlab/registry"
registry['registry_http_addr'] = "0.0.0.0:5050"
registry['debug_addr'] = "0.0.0.0:5051"
registry['log_directory'] = "/var/log/gitlab/registry"
registry['log_level'] = "info"

registry_nginx['enable'] = false

在 docker 上绑定端口5050:5050

创建外部 nginx 配置以侦听从https://registry.gitlab.example.com到http://127.0.0.1:5050的重定向流量

sudo tee /etc/nginx/sites-available/registry.gitlab.example.com <<EOF
server {
   listen 81;
   server_name registry.gitlab.example.com;

   server_tokens off; ## Don't show the nginx version number, a security best practice

   client_max_body_size 0;
   chunked_transfer_encoding on;

   location /
   {
      # let Nginx know about our auth file
      proxy_pass http://127.0.0.1:5050;
      proxy_set_header Host $host; # required for docker client's sake
      proxy_set_header X-Real-IP $remote_addr; # pass on real client's IP
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $scheme;
   }
}
EOF

使用 let's encrypt certbot 或任何其他提供商生成证书sudo certbot --nginx -d registry.gitlab.example.com

您现在应该能够访问注册表。
