docker-编排文件(compose file)

参考使用文档和语法文档

安装方法（Linux）

//下载
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.3/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
//授权
sudo chmod +x /usr/local/bin/docker-compose
//软链接
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
//测试
docker-compose --version

常用命令

//忽略缓存，重新构建镜像
docker-compose --no-cache build image1 image2 ...
//【后台】构建镜像，启动容器
docker-compose up -d
//关掉容器，并删除容器
docker-compose down
//关掉容器，并删除容器和没有指定tag的镜像（一般指那些从dockerfile创建的镜像，有更新文件时，这个比较好用）
docker-compose down --rmi local
