我在 Windows 10 上使用 Docker 创建 Debian 镜像。但是，我认为 Docker Desktop、Dockerfile 或 Docker 命令有问题。
在 Docker 桌面 ，我对默认配置做了三处更改。

在General下我打开了Expose daemon on tcp://localhost:2375 without TLS .

在资源 > 代理下，我有 http和 https配置。

在 WSL 集成下，我打开了 Ubuntu 18.04。

Dockerfile 导致问题如下:

FROM debian:buster-slim

ENV LANG=C.UTF-8 LC_ALL=C.UTF-8

RUN apt-get update --fix-missing && \
    apt-get install -y wget && \
    apt-get clean

CMD [ "/bin/bash" ]

如果它有帮助，这个替代 Dockerfile 运行没有问题:

FROM debian:buster-slim

ENV LANG=C.UTF-8 LC_ALL=C.UTF-8

RUN apt-get update --fix-missing && \
    apt-get clean

CMD [ "/bin/bash" ]

docker 命令我用来构建的Dockerfile如下:

>>> docker build simple-example

注: Dockerfile是目录 simple-example 中的唯一文件.
正在尝试构建 Dockerfile 与 docker 命令鉴于 Docker 桌面 配置导致以下错误:

这三个(Docker Desktop、Dockerfile 或 Docker 命令)中的哪一个会导致此错误？我应该怎么做才能修复它？

Answer 1

尝试将这两行放在 Dockerfile 中:

ENV http_proxy=http:...
ENV https_proxy=http:...
