- 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。
- Docker-Compose的工程配置文件默认为docker-compose.yml,可通过环境变量COMPOSE_FILE或-f参数自定义配置文件,其定义了多个有依赖关系的服务及每个服务运行的容器。
- Compose允许用户通过一个单独的docker-compose.yml模板文件(YAML 格式)来定义一组相关联的应用容器为一个项目(project)。
- Docker-Compose项目由Python编写,调用Docker服务提供的API来对容器进行管理。因此,只要所操作的平台支持Docker API, 就可以在其上利用Compose来进行编排管理。
创建文件夹:mkdir /etc/docker
跳转:cd /etc/docker
修改damon.json的内容:vim /etc/docker/daemon.json
{ "registry-mirrors": ["http://hub-mirror.c.163.com"] }
需要安装两个包(下载)
- docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
- docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
两个包放在word里面了
把两个包放入到/home下面
然后进入安装:
输入:yum install docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
输入:yum install docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
查看docker服务:systemctl status docker
设置开启自启docker服务:systemctl enable docker
启动docker服务:systemctl start docker
查看命令:docker version
下载:docker-compose-Linux-x86_64
创建:docker-compose.yml
拷贝docker-compose-Linux-x86_64到/usr/local/bin/并改名:mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose
添加权限:chmod +x /usr/local/bin/docker-compose
查看版本:docker-compose -v
