Docker登录不能使用nexus 3私有注册表



Nexus UI Config

我在linux虚拟机上运行Nexus Repository Manager OSS 3.0.1-01在那个虚拟机上,我有nginx工作保留代理http请求为https。我的SSL密钥由受信任的CA签名我创建了一个maven存储库,无论何时我有客户端机器发布到它,它都可以正常工作。

同样在这个客户端机器上,当我使用我的docker客户端,并做一个docker登录。我收到各种各样的错误。

我遵循这些指示https://books.sonatype.com/nexus-book/3.0/reference/docker.html#_accessing_repositories特别是第9.2节,老实说,我花了两天时间毫无进展。

我已经阅读了这里提到的所有内容:连接到存储在Azure虚拟机上Nexus 3预览版上的Docker注册表时遇到问题但是用户解释的设置让我很困惑。

对于我们试图通过将--insecure-registry添加到/etc/default/docker文件来实现不安全设置的设置,根本不是一个选项。

我已经尝试遵循多个教程只是为了了解docker注册表的内部工作,但我还没有能够拼凑它在一起。我在一定程度上遵循了这一点:https://www.digitalocean.com/community/tutorials/how-to-set-up-a-private-docker-registry-on-ubuntu-14-04

我在stackoverflow中使用了额外的响应来帮助我排除故障在nginx代理后使用docker私有注册表(v2)的错误HTTP响应

但老实说,我不能说我已经找到了任何可以直接理解这一点的东西。NGINX不报告任何错误日志在/var/log/nginx/errors.log中,访问日志看起来像基本的"GETS",每次我尝试docker登录。docker登录/var/log/upstart/docker.log报告了我下面用404错误说明的相同错误。也跟着这个问题在github上看看是否有任何帮助github com/docker/docker/issues/8410。任何帮助,让我能够执行一个成功的docker登录到这个私人nexus 3的仓库将是惊人的。

现在也许我有点困惑的一切,我一直在阅读让我的docker客户端与这个nexus repo成功地工作,但它是需要我设置一个docker(组)的repo,这是我的问题的来源?或者对我来说,仅仅拥有一个docker(托管)repo是可以的。因为到目前为止,我只有一个docker(托管)repo。Nexus的文档并没有给我留下这样的印象:要想让一切正常工作,还需要一个组的repo。

最后但并非最不重要的是,我希望我的问题足够具体,我希望你们看到我在这里做了一些努力。我真的尽力了!

当我登录时,我使用本地admin用户,使用默认的admin密码。首先让我提出问题:

如果我尝试没有端口,我得到以下——

root:~# docker login box.company.net
Error response from daemon: Login:
<!DOCTYPE html>
<html>
<head>
  <title>404 - Nexus Repository Manager</title>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>

使用4444的HTTP端口,我得到以下

root:~# docker login box.company.net:4444
Error response from daemon: Get https://box.company.net:4444/v1/users/: `http: server gave HTTP response to HTTPS client`

如果我在Nexus UI中添加HTTPS到4445,那么我运行

root:~# docker login box.company.net:4445
Error response from daemon: Get https://box.company.net:4445/v1/users/: dial tcp x.x.x.x:4445: getsockopt: connection refused

这是我的环境信息:

这里有一些基本的curl结果,如果这对你有帮助的话。

任何帮助获得docker登录prive.registry.net将非常有帮助,谢谢。

我必须在我的nginx配置中添加一个额外的(服务器)条目,就在前一个条目

重启nginx

docker客户端,将连接到端口6666,nginx将流量路由到端口4444,

# correlates to your nexus http connector
server {
    listen 6666;
    server_name box.company.net;
    keepalive_timeout 60;
    ssl on;
    ssl_certificate /etc/nginx/conf.d/net.crt;
    ssl_certificate_key /etc/nginx/conf.d/net.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;
    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;
      proxy_set_header        X-Forwarded-Proto "https";
      proxy_pass              http://x.x.x.x:4444;
      proxy_read_timeout      90;
    }
}

那么我可以写

docker login -u username -p password box.company.net:6666
docker pull box.company.net:6666/docker-image:tag
docker push box.company.net:6666/docker-image:tag
