docker登录不适用于nexus 3私有注册表
Nexus UI配置
我在Linux VM上运行Nexus Repository Manager OSS
3.0.1-01,在该VM上,我让nginx致力于将代理http请求保留为https。我的SSL密钥由受信任的CA签名,我创建了一个maven存储库,只要有客户端计算机发布,它就可以正常工作。
同样在此客户端计算机上,当我使用docker客户端并进行docker登录时。我收到各种错误。
我正在遵循以下说明https://books.sonatype.com/nexus-
book/3.0/reference/docker.html#_accessing_repositories
特别是9.2节,老实说,我已经花了最后两天了。
我已经阅读了这里提到的所有内容: 无法连接到存储在Azure VM上Nexus 3
Preview上的Docker注册表,但是用户进行的设置使我感到困惑。
对于设置,我们试图通过添加--insecure-registry
到/etc/default/docker
文件来实现不安全的设置,这根本不是一种选择。
我试图遵循多个教程,只是为了了解docker注册表的内部工作原理,但是我无法将其组合在一起。我已经在一定程度上关注了此问题:https :
//www.digitalocean.com/community/tutorials/how-to-set-up-a-private-docker-
registry-on-
ubuntu-14-04
我在stackoverflow中使用了其他响应来帮助我解决 nginx代理后面的docker private
Registry(v2)格式错误的HTTP响应
但是说实话,我不能说我已经找到了可以理解这一点的任何东西。NGINX没有报告任何错误登录/var/log/nginx/errors.log
,每次我尝试进行docker登录时,访问日志都看起来像基本的“
GETS”。码头工人登录后/var/log/upstart/docker.log
报告的错误与我在下面说明的404错误相同。还在github上关注了这个问题,看看对githubcom / docker / docker / issues / 8410是否有帮助。任何帮助我能够成功执行docker登录到此私人nexus3存储库的帮助都将是惊人的。
现在,也许我对正在阅读的所有内容都感到有些困惑,以使我的docker客户端能够成功地与该仓库回购一起工作,但这是否要求我设置一个docker(group)回购,这就是问题的根源吗?还是让我拥有一个docker(托管)回购协议就可以了。因为到目前为止,我只有一个docker(托管)仓库。Nexus文档给我的印象是,还需要小组回购才能使工作正常进行。
最后但并非最不重要的一点是,我希望我的问题足够具体,也希望大家看到我在这里做了一些努力。我确实尝试过!
登录时,我正在使用本地admin用户以及默认的admin密码。首先让我介绍一下这些问题:
如果我尝试不使用端口,则会得到以下结果-
root:~# docker login box.company.netError 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,我得到以下信息
root:~# docker login box.company.net:4444Error 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中将HTTPS添加到4445,则运行
root:~# docker login box.company.net:4445Error 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:

任何帮助使docker登录private.registry.net的帮助都将非常有帮助。
回答:
我必须在我的nginx配置中的前一个条目的正下方添加一个附加的(服务器)条目
docker客户端,将连接到端口6666,nginx会将流量路由到端口4444
