Docker BuildX 图像未显示在 docker 图像 ls 中

Docker BuildX image not showing in docker image ls

我目前正在尝试使用 BuildKit/BuildX 构建多平台映像(x86_64、arm64、armv7、armv6),它似乎构建成功,但我似乎无法找到图像所在的位置。它没有显示从我以前的 x86_64 构建中更改,并且当尝试 docker 将它推送 到我的 repo 时,它说所有层都已经存在,并且只有一个平台存在。我用来构建图像的命令是:

docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7,linux/arm/v6 -m 5120M --no-cache --progress auto --pull -t frostedflakez/php-mysql-webserver:php-latest-7.4 --push ./

构建后我从终端获得的最后一行是:

镜像直接推送到注册表:

无法将 multi-platform 图像推送到 docker 引擎。相反,引擎中的所有图像都是单一平台,您将 multi-platform 图像直接推送到选定的注册表。您可以拉取图像以获取适合您平台的版本:

docker image pull frostedflakez/php-mysql-webserver:php-latest-7.4

图像本身位于构建器缓存中,但无法从引擎访问。您可以通过以下方式查看缓存大小:

docker system df

您可以使用以下方法清理此缓存:

docker builder prune
