docker - 来自守护程序的错误响应 : Get http://localhost:8185/v2/: net/http: request canceled (Client. 等待 header 时超时)

Question

我正在运行 Ubuntu 18.04.5 虚拟机。

我开始了本地注册表。 compose文件和docker文件如下。

FROM registry

RUN apk add --no-cache apache2-utils

RUN mkdir /auth \
    && htpasswd -bnB admin admin > /auth/htpasswd

合成文件如下。

version: "3.8"

services:
  basic:
    build: .
    image: registrywithbasicauth:dev
    ports:
      - 8185:5000
    environment:
      REGISTRY_AUTH: htpasswd
      REGISTRY_AUTH_HTPASSWD_REALM: basic-realm
      REGISTRY_AUTH_HTPASSWD_PATH: /auth/htpasswd

当我尝试按如下方式进行 docker 登录时

docker login localhost:8185 -u admin -p admin

它给出以下输出。

Error response from daemon: Get http://localhost:8185/v2/: net/http:request canceled (Client.Timeout exceeded while awaiting headers)

docker info 提供以下内容。

我不确定发生了什么。

看了很多引用资料，至今都无法登录成功。

部分引用资料如下。

如有任何帮助，我们将不胜感激。

将 DNS 更改为 Google DNS 服务器。

将文件 /cat/resolv.conf 中的名称服务器更改为 8.8.8.8
