无法登录到Nexus注册中心(托管)

Question

我已经在nexus服务器https://nexus.mycompany.com中配置了Docker注册中心(宿主)，并在8083上启用了HTTP连接器端口。

我无法从我的Jenkins服务器将图像推送到Docker存储库。

我在Jenkins服务器.x的不安全注册中心中添加了连接服务器。

$ cat /etc/docker/daemon.json

{
  "insecure-registries": [
     "nexus.mycompany.com:8082",
     "nexus.mycompany.com:8083"
  ]
}

当我跑的时候

码头管理员登录-u -p xxxxx nexus.mycompany.com:8083

我得到以下错误

警告！通过CLI使用密码是不安全的。使用.密码-stdin。来自守护进程的错误响应:获取 ：拨号tcp xxx.x.0.xx:8083: connect: no路由到主机

我已经配置了，下面是我在Jenkins服务器中的conf.d .d文件。我是不是在代理设置中遗漏了什么？

I can connect to the Docker registry from the nexus server.
Jenkins server ports 
Below are my port settings on the Jenkins server.

Answer 1

这是简单的端口问题，.though，端口8083正在监听，它不接受流量。

我编辑了iptables，添加了8083以接受入站流量，并且我能够登录。
