1、查看 Composer 的全局配置选项的列表。打开命令行窗口并执行如下命令：镜像地址为官方源地址。如图1
PS E:\wwwroot\pcs-api> composer config --global --list

2、打开 阿里云 Composer 全量镜像 网址：https://developer.aliyun.com/composer
3、系统全局配置： 即将配置信息添加到 Composer 的全局配置文件 config.json 中。打开命令行窗口并执行如下命令：
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
4、在 Docker 部署 中，在全局配置中启用 阿里云 Composer 全量镜像，编辑文件 Dockerfile，如图3
FROM registry-vpc.cn-beijing.aliyuncs.com/cmc/centos-nginx112-php72:0.1.7

chmod +x /usr/local/bin/composer && \
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/ && \
cd /sobey/www/pcs-api && \
composer install
5、重新构建 Docker 镜像，执行过程更加快速与稳定。之前耗时 35 分钟，现在耗时 18 分钟，如图4、图5
