常见命令解释
FROM 指定镜像源
FROM ubuntu# Base Dockerfile for gRPC dev images
FROM debian:latest网站http://hub.docker.com FROM命令是用来指定你需要用哪个镜像作为基础镜像进行构建一般来说Dockerfile的第一行都会先指定一个镜像官方仓库中有很多镜像可以通过http://hub.docker.com进行搜索建议尽量使用官方镜像作为基础镜像因为官方镜像都是精简过的稳定版。
RUN 执行linux命令
比如我们需要安装vim 写法1
RUN apt-get update -y
RUN apt-get install -y vimRUN是用来执行linux命令的指令例如ubuntu系统下需要更新软件包list就需要执行apt-get update之后会跟着执行apt-get install 写法2
RUN apt-get update -y \ apt-get install -y vim参考例子

声明端口作用是帮助镜像使用者理解这个镜像服务的守护端口以方便配置映射。在运行时使用随机端口映射时也就是 docker run -P时会自动随机映射EXPOSE的端口。
EXPOSE 端口1 [端口2...]在 Dockerfile 中写入这样的声明有两个好处:
一个是帮助镜像使用者理解这个镜像服务的守护端口以方便配置映射;另一个用处则是在运行时使用随机端口映射时也就是 docker run -P 时会自动随机映射 EXPOSE 的端口。 例子
EXPOSE 端口号
EXPOSE 端口号/协议默认协议是 TCP
EXPOSE 80/tcp
EXPOSE 80/udpFROM nginx
EXPOSE 80在docker-compose中
通常在docker-compose中会通过ports来映射并暴露端口docker-compose用法如下
ports:- 8001:80
