安装 docker-compose

使用 Docker 释放安装

• 由于部分网络从Github 下载安装较慢,
• 运行命令, 使用 Docker 释放安装
• 按需选择安装版本, 版本区别尚未观察, 详情查阅 https://github.com/docker/compose/releases

docker run --privileged --rm -v /usr/local/bin/:/dest registry.cn-hangzhou.aliyuncs.com/lwmacct/file:1657436749-docker-compose-v2.6.1

docker run --privileged --rm -v /usr/local/bin/:/dest registry.cn-hangzhou.aliyuncs.com/lwmacct/file:1649397829-docker-compose-v2.4.1
