概要

docker buildx 打包 arm 架构镜像时，报错 ERROR: failed to solve: openjdk:8-jdk: failed to resolve source metadata for docker.io/library/openjdk:8-jdk: failed to authorize: failed to fetch anonymous token: Get “https://docker.m.daocloud.io/auth/token?scope=repository%3Alibrary%2Fopenjdk%3Apull&service=docker.m.daocloud.io": net/http: TLS handshake timeout

原因

由于 docker buildx 网路路径比较复杂，外部开启 clash 之后，会导致 buildx 构建容器中无法访问授权接口。

思路

关闭 clash，添加镜像站，运行

1

docker buildx build --platform linux/arm64 -t registry.cn-hangzhou.aliyuncs.com/gear-repo/qfg-fzyp-service-arch64 --load .
