错误：无法解决：无法获取 OAuth 令牌："https://auth.docker.io/token" 后：拨号 TCP：I/O 超时

Question

我试图在我的M1 max MacBook上为我的java文件建立一个docker映像，我的dockerfile:

FROM openjdk:8-alpine
COPY . /src/java
WORKDIR /src/java
RUN ["javac","greenchallenge.java"]
ENTRYPOINT ["java","greenchallenge"]

构建映像的步骤:

1. 创建了一个新的构建器:docker buildx create --name pibuilder(我想使用多架构特性)
2. 使用docker buildx use pibuilder初始化构建器。
3. 构建图像并使用:

docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 -t my_java:latest -t my_java:1.0.0 --push .

运行step3后，我得到了下面的日志:

注意:我用的是工作环境，我也绕过了代理。注意:如前所述，我在终端设置了"buildkit":false，使用了docker login。

希望你能帮我解决这个错误，提前谢谢。

将buildkit选项设置为false是不够的，如果您在代理后，您应该设置HTTP_PROXY和HTTPS_PROXY的env变量使其工作

(Windows)，在CMD中:

set HTTP_PROXY=YourProxyUrl:Port
set HTTPS_PROXY=YourProxyUrl:Port

export HTTP_PROXY=YourProxyUrl:Port
export HTTPS_PROXY=YourProxyUrl:Port
