Alpine命令
https://wiki.alpinelinux.org/wiki/Alpine_Linux_package_management

alpine里安装bash
https://github.com/yikaus/docker-alpine-bash

docker pull yikaus/alpine-bash
docker run --rm -ti yikaus/alpine-bash /bin/bash

自己编译镜像

cat Dockerfile 
FROM alpine:3.5

MAINTAINER liang <[email protected]>
RUN apk add --update bash && rm -rf /var/cache/apk/*

编译成镜像
docker build  -t alpinebash .

docker run --rm -ti alpinebash /bin/bash 进入bash

Alpine镜像安装nginx

FROM alpine:latest
MAINTAINER liang [email protected]

RUN mkdir /run/nginx && mkdir /data
# install nginx
RUN apk --update add nginx && apk add --update bash && rm -rf /var/cache/apk/*
ADD nginx.conf /etc/nginx/nginx.conf
ADD index.html /data/index.html

EXPOSE 80

CMD ["nginx", "-g", "daemon off;"]

编译镜像
docker build -f Dockerfile -t alpinenginx .
运行
docker run --name=anginx -d -p 8088:80 alpinenginx


开放8088端口防火墙
访问：http://192.168.1.181:8088/ 报404

docker exec -ti anginx /bin/bash 进入bash里查看nginx配置
docker cp anginx:/etc/nginx/nginx.conf nginx.conf
增加配置
server
        {
    
    
                listen       80;
                server_name localhost;
                location /{
    
    
                        root  /data;
                        index index.html index.htm index.php default.html default.htm default.php;
                }
        }
注释这个
#include /etc/nginx/conf.d/*.conf;

编译镜像时增加nginx.conf 和一个index.html文件
访问：http://192.168.1.181:8088/

自己编译nginx基础镜像
