RedundantTarget平台

输出

Setting platform to predefined $TARGETPLATFORM in FROM is redundant as this is the default behavior

自定义平台可用于基础镜像。默认平台是与目标输出相同的平台，因此将 Platform 设置为是冗余且不必要的。$TARGETPLATFORM

❌ Bad：此用法是多余的，因为是默认值。--platform$TARGETPLATFORM

FROM --platform=$TARGETPLATFORM alpine AS builder
RUN apk add --no-cache git

✅ Good：省略参数。--platform

FROM alpine AS builder
RUN apk add --no-cache git
