4、使用多阶段构建来减小大小 为了显着减小大小，我们可以使用 docker 多阶段构建的概念。这里我们使用不同的 images/Dockerfile 来构建和打包应用代码。它将 Dockerfile 分成多个阶段，并将所需的工件从一个阶段传递到另一个阶段，然后在最后一个阶段交付缩小镜像大小的最终镜像。它显着减小镜像尺寸。# Official dock...
# You᾿ll now have two images, 907ad6c2736f with /bar, and 695d7793cbe4 with # /oink. 在上面的Dockerfile中一共出现了三次FROM命令,这就意味着当这个Dockerfile执行完毕之后,会同时生成三个镜像,但只会输出最后一个镜像的ID值,中间两个镜像只会被标记为:。所以是否需要在一个Dockerfile中同时生成...

Images must have a singleDockerfileper entry in the library file that can be used for multiple architectures. This means that each supported architecture will have the sameFROMline (e.g.FROM debian:bookworm). Seegolang,docker,haproxy, andphpfor examples of library files using oneDockerfileper...
