推送到本地 docker 注册表会出现连接重置错误

Question

我正在尝试按照本指南创建一个私有 Docker 注册表。我已经下载并标记了一个 Ubuntu 映像并创建了一个注册表容器，现在我打算将其推送到我的注册表，但是当我调用时，sudo docker push localhost:6000/Ubuntu我得到以下输出：

The push refers to a repository [localhost:6000/ubuntu] Put http://localhost:6000/v1/repositories/ubuntu/: http: can't write HTTP request on broken connection

我所能找到的只是“无法写入 HTTP 请求”错误是一个 Go 错误，但不幸的是我无法找到与如何在 Docker 中解决它有关的任何内容。我还尝试查找 Docker 命令的日志，以便我可以尝试获取有关该问题的更多详细信息，但日志似乎仅适用于容器，并且我没有在容器上运行它。

我该如何解决这个错误？

更新

我在没有进行任何更改后再次运行该命令并收到了不同的错误：

Put http://localhost:6000/v1/repositories/ubuntu/: read tcp [::1]:33417->[::1]:6000: read: connection reset by peer

更新2

再次，在没有进行任何更改后运行它，现在得到：

Put http://localhost:6000/v1/repositories/ubuntu/: EOF

更新3

经过一番折腾后，我发现我尝试推送到注册表的映像确实出现在我的 docker 映像列表中，但我似乎无法拉取它。

更新4

经过一番折腾后，我分配给私有注册表的端口似乎只监听 IPV6，而不是 IPV4。根据这个git线程，docker看起来只监听IPV6是正常的，但是在运行telnet localhost、、netstat -ntlp和之后iptables -t nat -nxvL，我仍然没有看到任何迹象表明任何东西正在监听127.0.0.1:6000，这是我的端口应该分配给registry（它只是作为容器运行）。相反，它似乎正在监听 :::1:6000。

另外，因为这是有人要求的，而且因为我无论如何都应该列出它：

注册表日志以发生错误结束，但从日志的其余部分我实际上无法辨别该错误是什么。我什至将日志拆分为 stdout 和 stderr，但 stderr 中没有任何内容。

另外，我已经确认注册表正在侦听 ipv4。运行nc -l -4 6000返回Address already in use。至少，我想我已经证实了这一点。ipv4 地址仍然不会显示netstat。

更新6

使用 显式指定一个 ipv4 端口docker run -d -p 127.0.0.1:8000:8000，该端口在 netstat 中显示为正在侦听。仍然遇到同样的错误。不过 Docker 日志有点不同：

“redis 未配置”消息是唯一看起来可能存在问题的消息。要去调查一下。真的非常非常感谢任何额外的见解。

Answer 1

解决了问题：

不得不跑docker run -d -p 127.0.0.1:6000:5000。不使用 localhost 确保使用了 ipv4（我很确定它以其他方式使用，但至少现在它显示在 netstat 中）并且容器侦听其端口 5000，因此它无法正常工作。
