Nginx Docker 400 错误请求

Question

我目前正在尝试将 nexus 托管为我组织内 docker 图像的私有注册表。我的 nginx 配置如下。

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    server {

            listen 6666;   ### Docker Hosted Repo HTTPS port
            server_name box.company.net;  ### Nexus Server
            keepalive_timeout 60;

            ssl on;
            ssl_certificate /etc/ssl/certs/nexus.crt;
            ssl_certificate_key /etc/ssl/certs/nexus.key;
            ssl_ciphers HIGH:!kEDH:!ADH:!MD5:@STRENGTH;
            ssl_session_cache shared:TLSSSL:16m;
            ssl_session_timeout 10m;
            ssl_prefer_server_ciphers on;

            client_max_body_size 0;
            chunked_transfer_encoding on;

            location /v2/ {


                    if ($http_user_agent ~ "^(docker\/1\.(3|4|5(?!\.[0-9]-dev))|Go ).*$" ) {
                    return 404;
                    }
                    error_log               /var/log/nginx/error.log debug;
                    access_log              /var/log/nginx/docker.log;
                    proxy_set_header        Host $http_host;
                    proxy_set_header        X-Real-IP $remote_addr;
                    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
                    proxy_set_header        X-Forwarded-Proto "https";
                    proxy_pass             http://box.company.net:4444/;
                    proxy_read_timeout      900;
        }

            location / {

                    error_log               /var/log/nginx/error.log debug;
                    access_log              /var/log/nginx/docker.log;
                    proxy_set_header        Host $http_host;
                    proxy_set_header        X-Real-IP $remote_addr;
                    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
                    proxy_set_header        X-Forwarded-Proto "https";
                    proxy_pass              http://box.company.net:4444/;
                    proxy_read_timeout      90;
        }
    }

已在 nexus（运行在端口 4444 上）和 https 端口 6666 中配置了托管 docker 存储库。

目前我们可以登录 docker 注册表。

[test@server ~]$ docker login -u admin -p admin123 box.company.net:6666 Login Succeeded

但是当我们尝试将标记图像推送到 nexus 托管 docker 注册表时，它会返回 400 Bad Request 错误。

[test@server ~]$ docker push box.company.net:6666/alpine The push refers to a repository [box.company.net:6666/alpine] 3fb66f713c9f: Preparing error parsing HTTP 400 response body: invalid character '<' looking for beginning of value: "\n\n\n\n 400 - Nexus Repository Manager\n \n\n\n \n (new Image).src=\"https://box.company.net:6666/favicon.ico?3.2.1-01\"</script>\n \n https://box.company.net:6666/favicon-32x32.png?3.2.1-01\" sizes=\"32x32\">\n https://box.company.net:6666/safari-pinned-tab.svg?3.2.1-01\" color=\"#5bbad5\">\n https://box.company.net:6666/favicon-16x16.png?3.2.1-01\" sizes=\"16x16\">\n https://box.company.net:6666/favicon.ico?3.2.1-01\">\n https://box.company.net:6666/mstile-144x144.png?3.2.1-01\">\n \n\n https://box.company.net:6666/static/css/nexus-content.css?3.2.1-01\"/>\n\n\n\n https://box.company.net:6666\">\n \n https://box.company.net:6666/static/images/nexus.png?3.2.1-01\"/>\n \n \n \n Nexus Repository Manager\n \n \n OSS 3.2.1-01\n \n \n \n\n\n\n \n https://box.company.net:6666/static/rapture/resources/icons/x32/exclamation.png?3.2.1-01\"/>\n Error 400\n Bad Request\n \n \n \n

我是否遗漏了一些重要的 nginx 配置？还是我的请求格式不正确。

Answer 1

推送图像时缺少命名空间。

查看文档 (https://books.sonatype.com/nexus-book/3.0/reference/docker.html#_accessing_repositories):

docker <command> <nexus-hostname>:<repository-port>/<namespace>/<image>:<tag>

你可以试试

docker push server.int.org.com:6666/alpine/alpine

Answer 2

它正在工作。下面是我的 nginx 配置。

server {

    proxy_send_timeout 120;
    proxy_read_timeout 300;
    proxy_buffering    off;
    tcp_nodelay        on;

    server_tokens off;
    client_max_body_size 1G;

    listen 80;
    server_name box.company.net;
    location / {
          rewrite ^(.*) https://box.company.net permanent;
    }
}

server {

    listen 443;
    server_name box.company.net;
    keepalive_timeout 60;
    ssl on;
    ssl_certificate /etc/ssl/certs/nexus.crt;
    ssl_certificate_key /etc/ssl/certs/nexus.key;
    ssl_ciphers HIGH:!kEDH:!ADH:!MD5:@STRENGTH;
    ssl_session_cache shared:TLSSSL:16m;
    ssl_session_timeout 10m;
    ssl_prefer_server_ciphers on;

    location / {

      proxy_set_header        Host $http_host;
      proxy_set_header        X-Real-IP $remote_addr;
      proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header        X-Forwarded-Proto "https";
      proxy_pass              http://box.company.net:8082;
      proxy_read_timeout      90;

    }
}

# correlates to your nexus http connector
server {

    listen 6666;
    server_name box.company.net;
    keepalive_timeout 60;
    ssl on;
    ssl_certificate /etc/ssl/certs/nexus.crt;
    ssl_certificate_key /etc/ssl/certs/nexus.key;
    ssl_ciphers HIGH:!kEDH:!ADH:!MD5:@STRENGTH;
    ssl_session_cache shared:TLSSSL:16m;
    ssl_session_timeout 10m;
    ssl_prefer_server_ciphers on;
    client_max_body_size 1G;
    chunked_transfer_encoding on;

    ### Block for Search,Pull,Push of Docker Images via Nexus Hosted Repo ####
    location / {

      access_log              /var/log/nginx/docker.log;
      proxy_set_header        Host $http_host;
      proxy_set_header        X-Real-IP $remote_addr;
      proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;

        if ($request_method !~* GET) {
                proxy_pass              http://box.company.net:4444;
        }
        if ($request_method = GET) {
                proxy_pass              http://box.company.net:5555;
        }
      proxy_read_timeout      90;
