在AWS上的nginx后面部署https docker注册表

我正在尝试在 EC2 instance 上使用 nginx 作为反向代理部署一个通用注册表实例(npm私有注册表docker私有注册表) . 这样做我希望能够通过https和身份验证将npm包和docker映像分别推送到 registry.mydomain.orgdocker.mydomain.org .

为此,我按照以下步骤操作:

  • 我从AWS控制台创建了一个EC2实例,从安全组选项打开HTTP端口(例如8080)

  • 我使用HTTPS创建了一个新的Load Balancer,将其连接到实例的HTTP端口 .

  • 我使用此配置创建了一个 docker-compose.yml 文件(我使用verdaccio作为npm私有注册表和registry:2作为docker注册表:

version: '3'
    services:
      nginx:
        image: nginx:alpine
        container_name: nginx
        restart: always
        ports:
          - "80:80"
        volumes:
          - ./nginx:/etc/nginx/conf.d/
          - ./nginx/nginx.conf:/etc/nginx/nginx.conf:ro
        links:
          - verdaccio:verdaccio
          - docker:docker

      verdaccio:
        image: verdaccio/verdaccio:latest
        container_name: verdaccio    
        restart: always
        ports:
          - "4873:4873"
        volumes:
          - ./registry:/verdaccio/conf
          - ./database/verdaccio:/verdaccio/storage 

      docker:
        image: registry:2
        container_name: docker
        restart: always
        ports:
          - "5000:5000"
        volumes:
          - ./database/docker:/var/lib/registry
  • nginx配置( nginx.conf )是:
events {
        worker_connections  1024;
    }

    http {
        upstream docker-registry {
            server docker:5000;
        }

        upstream npm-registry {
            server verdaccio:4873;
        }

        ## Set a variable to help us decide if we need to add the
        ## 'Docker-Distribution-Api-Version' header.
        ## The registry always sets this header.
        ## In the case of nginx performing auth, the header will be unset
        ## since nginx is auth-ing before proxying.
        map $upstream_http_docker_distribution_api_version     $docker_distribution_api_version {
            '' 'registry/2.0';
        }

        # Healtcheck
        server {
            listen 80;
            location /healthcheck {
                access_log off;
                return 200;
            }
        }

        server {
            # Server options
            listen 80;
            charset utf-8;
            client_max_body_size 0;

            server_name registry.mydomain.org;

            # Proxy settings
            location / {
                access_log /var/log/nginx/verdaccio.log;
                proxy_pass http://npm-registry;
                proxy_set_header Host $host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-NginX-Proxy true;
                proxy_ssl_session_reuse off;
                proxy_redirect off;
            }
        }

        server {
            # Server options
            listen 80;
            charset utf-8;
            client_max_body_size 0;

            # required to avoid HTTP 411: see Issue #1486 (https://github.com/moby/moby/issues/1486)
            chunked_transfer_encoding on;

            server_name docker.mydomain.org;

            # Authentication
            auth_basic "Registry realm";
            auth_basic_user_file /etc/nginx/conf.d/nginx.htpasswd;

            # Proxy settings
            location / {

                if ($http_user_agent ~ "^(docker\/1\.(3|4|5(?!\.[0-9]-dev))|Go ).*$" ) {
                    return 404;
                }

                ## If $docker_distribution_api_version is empty, the header will not be added.
                ## See the map directive above where this variable is defined.
                add_header 'Docker-Distribution-Api-Version' $docker_distribution_api_version always;

                access_log /var/log/nginx/docker.log;
                proxy_pass http://docker-registry;
                proxy_read_timeout 900;
            }
        }
    }
  • 我使用编码的身份验证信息创建了一个 nginx.htpasswd 文件 .

现在,注册表完美地运作了 . 所以如果我访问 https://registry.mydomain.org 我可以看到它,我可以通过 npm login --registry=https://registry.mydomain.org --scope=@myscope 将npm包推送到它

然而,关于 docker registry ,虽然我绝对可以使用 docker login -u user -p password 登录它,但是当我尝试将图像推送到它时,docker客户端进入无限循环并继续尝试上传图像(没有成功) . 在服务器端,docker注册表的日志没有显示有关正在进行的操作的有用信息,因为所有请求都以202 HTTP状态结束 .

关于如何解决它的任何提示?

    我想到了 . 我在nginx代理配置中缺少 proxy_set_header Host $host; .

    这样做:

    server {
            # Server options
            listen 80;
            charset utf-8;
            client_max_body_size 0;
    
            # required to avoid HTTP 411: see Issue #1486 (https://github.com/moby/moby/issues/1486)
            chunked_transfer_encoding on;
    
            server_name docker.cubbit.net;
    
            # Authentication
            auth_basic "Registry realm";
            auth_basic_user_file /etc/nginx/conf.d/nginx.htpasswd;
    
            # Proxy settings
            location / {
                # Do not allow connections from docker 1.5 and earlier
                # docker pre-1.6.0 did not properly set the user agent on ping, catch "Go *" user agents
                if ($http_user_agent ~ "^(docker\/1\.(3|4|5(?!\.[0-9]-dev))|Go ).*$" ) {
                    return 404;
                }
    
                ## If $docker_distribution_api_version is empty, the header will not be added.
                ## See the map directive above where this variable is defined.
                add_header 'Docker-Distribution-Api-Version' $docker_distribution_api_version always;
    
                access_log /var/log/nginx/docker.log;
                proxy_pass http://docker-registry;
                proxy_set_header Host $host;
                proxy_read_timeout 900;
            }
        }
    

    它开始完美运作 . 希望这可以帮助别人 . 我花了两天时间 .
