docker-compose编排

创建并启动容器

docker-compose up -d

备注：
-d  后台启动并运行容器

前提是你在执行该命令的时候已经编写好了docker-compose.yml文件，在这个文件的当前目录执行上述命令

 

centos7安装docker-compose

下载安装

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

授权
chmod +x /usr/local/bin/docker-compose

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

查看安装情况
[root@dmpdev ~]# docker-compose -version
