如何在 docker buildx

如何解决如何在 docker buildx

我想用 buildx 构建一个多架构映像。这是我的 GitLab CI 管道。第一步，我构建codebase:latest 图像。此映像的构建过程很困难，但最终仅包含静态文件。我想在构建 $CI_REGISTRY_IMAGE/Nginx:latest 和 $CI_REGISTRY_IMAGE/PHP:latest 图像时使用这些文件。

当我使用简单的 docker build 时，它的工作正常：

# Part of ./.deploy/Nginx/Dockerfile
copY --from=codebase /app/public /app/public

但是，当我使用 buildx 时出现错误。

我该如何解决这个问题？

Dockerfile:5
--------------------
   3 |     copY app.conf /etc/Nginx/conf.d/default.conf
   4 |     copY Nginx.conf /etc/Nginx/Nginx.conf
   5 | >>> copY --from=codebase /app/public /app/public
   6 |     workdir /app
   7 |     
--------------------
