构建过程

1、构建过程
- 从基础镜像运行一个容器
- 执行一条指令，对容器做出修改
- 执行类似docker commit的操作，提交一个新的镜像层
- 在基于刚提交的镜像运行一个新容器
- 执行Dockerfile中的下一条指令，直至所有指令执行完毕
  
  ps:构建中会删除中间层容器，而不会删除中间层镜像，所以可以使用中间层镜像进行调试，查找错误
2、镜像缓存
- 构建缓存: 构建一次后再构建就会使用构建缓存
- 不使用缓存
  - 使用--no-cache选项
  - 或
  - ENV REFRESH_DATE 2019-4-7

3、查看镜像构建的过程

docker history [image]
- --no-trunc: 不截断输出完整信息

只显示构建命令

docker history --format { {.CreatedBy} } --no-trunc=true e01eb2e99ca6 |sed "s?/bin/sh\ -c\ \#(nop)\ ??g"|sed "s?/bin/sh\ -c?RUN?g" | tac
