如何为 docker 文件中的 docker 图像提供参数，使其在 Apple M1 Machine 中仍然有效
How to give parameter to a docker image in docker file so that it still works in Apple M1 Machine
我以前可以下载 openjdk:8-jdk-slim 如下
docker run -it --name my-container openjdk:8-jdk-slim
迁移到 Apple M1 MacBook Pro 后，我必须使用此参数 --platform linux/amd64，如 https://docs.docker.com/docker-for-mac/apple-silicon/
中所述
docker run -it --platform linux/amd64 --name my-container openjdk:8-jdk-slim
但是我有一个 Dockerfile
FROM openjdk:8-jdk-slim
// Other codes
如何向它添加所需的参数，以便 Dockerfile 仍然可以在我的 Apple M1 MacBook Pro 上运行？
您也可以将 --platform 选项添加到 FROM 语句：
FROM --platform=linux/amd64 openjdk:8-jdk-slim
...
在Dockefile reference中提到：
The optional --platform flag can be used to specify the platform of the image in case FROM references a multi-platform image. For example, linux/amd64, linux/arm64, or windows/amd64. By default, the target platform of the build request is used. Global build arguments can be used in the value of this flag, for example automatic platform ARGs allow you to force a stage to native build platform (--platform=$BUILDPLATFORM), and use it to cross-compile to the target platform inside the stage.
