Docker跨架构编译

Docker跨架构编译

1.启用buildx

环境暴露

export DOCKER_CLI_EXPERIMENTAL=enabled

验证是否开启：

docker buildx version

启用 binfmt_misc

如果你使用的是 Docker 桌面版（MacOS 和 Windows），默认已经启用了 binfmt_misc，可以跳过这一步。

docker run --rm --privileged docker/binfmt:66f9012c56a8316f9244ffd7622d7c21c1f6f28d

2.create

Docker 默认会使用不支持多 CPU 架构的构建器，我们需要手动切换。

docker buildx create --use --name mybuilder

3.bootstrap启动构建器

docker buildx inspect mybuilder --bootstrap

docker buildx inspect mybuilder --bootstrap

4.构建镜像buildx

需要提前通过 docker login 命令登录认证 Docker Hub。

docker buildx build -t aa/aa --platform=linux/arm,linux/arm64,linux/amd64,linux/386,linux/arm/v7 . --push

docker buildx build -t qqfirst/mariadb --platform=linux/arm,linux/arm64,linux/amd64,linux/386 . --push
