Understanding of Docker multi-stage build: Building an image requires a base image, and subsequent operations will be built based on the base image There is a layered concept in the docker image file. Each time the RUN instruction is executed, the image will have one more layer, so the image size can be reduced by reducing the layers When there are multiple froms, only the image of the last from

FROM Specify the base image used to build the image. FROM must be the first instruction in the non-comment line in the Dockerfile. If there is no specified image locally, it will automatically pull the image from the Docker public library. Example: Copy 1 FROM ubuntu:14.04 #Inherit ubuntu:14.04 MAINTAINER Specify creator information Copy 1 MAINTAINER wanzi "iwz2099@163.com" ENV Set environment variables, which will be used by subsequent RUN instructions and
