Docker笔记 示例DockerfileFROM alpine:latest ARG TAG=0.0.1 ARG PORT_ARG=3080 RUN apk add --no-cache bash # 切换默认shell为bash SHELL ["/bin/bash", "-c"] RUN echo tag=$TAG RUN echo port_tag=$PORT_ARG构建docker build --no-cache --progress plain --rm --build-arg TAG=0.0.3 --build-arg PORT_ARG=3000 --tag hello/world:0.0.3 .运行docker run hello/world:0.0.3笔记ARG 用来声明参数，语法为ARG <key>=<default-value>，需要在在FROM之后才会有作用build时, 通过--build-arg的方式传递，语法为--build-arg <key>=<value>, 可以多组参考How To Pass Environment Info During Docker BuildsDocker: How to use bash with an Alpine based docker image?
