在windows上构建docker映像|代理问题

Question

我试图从docker容器中安装curl，但由于以下错误而失败，我尝试设置代理-No go

尝试的步骤：

>

使用Dockerfile构建docker

使用构建参数HTTP_PROXY构建 Docker 构建

docker登录到repo，然后尝试构建镜像-no go

使用 env 代理更新 config.json 文件 - 不行

使用不同的代理

试图刷新windows pc上的html" target="_blank">DNS

docker构建传递环境上下文

更改docker桌面设置对于Web Server和Secure Web Server，输入：代理

绕过代理设置，输入localhost-Apply

请进一步告知 - 谢谢

$ docker run -ti - env HTTPS_PROXY= "

# apk add --no-cache curl 
fetch https://dl-cdn.alpinelinux.org/alpine/v3.13/main/x86_64/APKINDEX.tar.gz

Answer 1

下载证书：示例.crt

将example.crt复制到容器内的 /etc/ssl/certs/example.crt

将 example.crt 的内容添加到 /etc/ssl/certs/ca-certificates.crt

cat /etc/ssl/certs/example.crt >> /etc/ssl/certs/ca-certificates.crt

将环境HTTPS_PROXY变量设置为 http://{代理}：{端口}

export HTTPS_PROXY=http://{proxy}:{port}

运行apk更新或从外部资源安装其他软件包

Dockerfile

 FROM alpine:latest

 # This could also be passed as a build argument
 ENV HTTPS_PROXY=http://{proxy}:{port}

 COPY example.crt /etc/ssl/certs/example.crt
 RUN cat /etc/ssl/certs/example.crt >> /etc/ssl/certs/ca-certificates.crt

 RUN apk update

这解决了问题。
