安装 Docker-Compose （不是必要）[url=]

# Docker-Compose项目是Docker官方的开源项目，负责实现对Docker容器集群的快速编排。# Centos8提供了pip3,没有pip，想自己安装的话，也会找不到合适的版本。pip3 install -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com --upgrade pippip3 install -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com docker-compose[url=]
