Docker：nginx镜像多级构建

制作alpine Base镜像B【基于官方alpine镜像A】

root@ubuntu:~/system/alpine# cat Dockerfile

FROM registry.cn-hangzhou.aliyuncs.com/qiushi/alpine:3.18.0
LABEL image="base"
#COPY repositories /etc/apk/repositories

#添加系统账户

     adduser -u 2024 -G www -D -S -s /sbin/nologin www 

root@ubuntu:~/system/alpine# cat build.sh

#/bin/bash
docker build -t registry.cn-hangzhou.aliyuncs.com/qiushi/alpine-3.18.0:$1  .

nginx镜像多级构建【基于B、A】

准备nginx.conf文件

user  www;
worker_processes  auto;
...
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  logs/access.log  main;
.....
include conf.d/*.conf; 
}

root@ubuntu:~/web/nginx# cat Dockerfile

#多级构建，第1级：不产生新镜像
#1、nginx只编译部分，只是编译文件，并将编译文件传给下一个镜像镜像制作阶段

#多级构建，第2级：产生新镜像
#1、将第一级构建部分cp过来
#2、采用最简洁的官方alpine镜像，没有额外包，镜像最终数据达到最小
