Docker 錯誤：standard_init_linux.go:228: exec 用戶進程導致：exec 格式錯誤

Question

我能夠從 arm64 的 M1 Macbook 成功構建多架構映像。 這是我的 docker 文件並嘗試從 raspberrypi aarch64/arm64 運行，運行圖像時出現此錯誤： standard_init_linux.go:228: exec user process caused: exec format error

使用 python 文件編輯帖子：

基於 MacOS 構建的“多架構”Python 解釋器旨在針對 MacOS-on-Intel 和 MacOS-on-Apple's-arm64。

與 Linux-on-Apple's-arm64或Linux-on-aarch64 絕對沒有二進制兼容性。 無論架構是否匹配，您都無法在 Linux 上運行 MacOS 可執行文件。

當您在操作系統/平台與您想要啟動容器的平台不同的機器（主機）中構建映像時，就會發生這種情況。

解決方案是使用相同的機器/操作系統（需要運行它/需要啟動容器）來構建 docker 映像。

就我而言，我在 OSX 主機中構建 NodeJS、Python、Nginx、redis 和 postgres 映像，並試圖從 Ubuntu debian 主機中的映像啟動容器。 我通過在 Ubuntu debian 中構建圖像並在同一平台（Ubuntu debian）中擴展容器來解決

如果 Docker 鏡像構建在 M1 芯片上並上傳以供 Fargate 部署，那么您會在 Fargate 中注意到此容器錯誤：

standard_init_linux.go:228: exec user process caused: exec format error

有幾種方法可以解決這個問題。 您可以：

• 使用以下命令構建您的 docker 映像：

docker buildx build --platform=linux/amd64 -t image-name:version .

• 更新您的 Dockerfile 的FROM語句

FROM --platform=linux/amd64 BASE_IMAGE:VERSION
