dockers三驾马车
Docker Compose是一个定义和运行多容器应用的单机编排工具。通过Docker Compose你可以使用一个单一的YAML文件来配置多个应用服务，通过一条命令，就可以将所有配置的服务全部启动起来。
使用Dockerfile定义环境，这样可以确保其在任意地方运行
使用docker-compose.yml文件定义服务，这样它们就可以在独立环境中一起运行
运行docker-compose up使用docker-compose启动所有应用
启动、停止、重建服务
查看服务的运行状态
流式输出服务日志
对服务执行一次性命令

同时还有安装方式，也可以wget下载上面的文件，本身也是一个二进制文件
[root@docker-server3 ~]# curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

[root@docker-server3 ~]# chmod +x /usr/local/bin/docker-compose
[root@docker-server3 ~]# docker-compose --version
docker-compose version 1.25.0, build 0a186604
[root@docker-server3 ~]# mkdir /docker-compose
[root@docker-server3 ~]# cd /docker-compose
写一个简单的dockerpose文件
[root@docker-server3 docker-compose]# vim docker-compose.yml
version: ‘3‘ services: httpd-test: image: httpd:2.4
[root@docker-server3 docker-compose]# docker-compose up -d

删除然后在执行，就会拉去一个一样的镜像
[root@docker-server3 docker-compose]# docker rm -f 06a7e97739b2
[root@docker-server3 docker-compose]# docker-compose up -d
[root@docker-server3 docker-compose]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES d184230f2de6 httpd:2.4 "httpd-foreground" 3 seconds ago Up 2 seconds 80/tcp docker-compose_httpd-test_1
同时创建两个容器，修改compose文件
[root@docker-server3 docker-compose]# vi docker-compose.yml
version: ‘3‘ services: httpd-test: image: httpd:2.4 httpd-test-2: image: httpd:2.4 volumes: - "/data:/var/www/html" ports: - "80:80"

[root@docker-server3 docker-compose]# curl http://192.168.132.133:8080/111.html
111
以上就是docker的一个简答的操作
在上面的一个简单示例中，我们已经使用了docker-compose up来启动一个docker-compose.yml文件定义的服务。刚刚通过docker-compose up虽然启动了服务，当是docker-compose指令却在前台执行，如果需要将其放入后台运行，可以使用-d参数：
docker-compose up -d #后台运行 docker-compose -f xx.yaml up -d #如果yml文件不是docker-compose.yml需要使用-f强制指定 docker-compose down #删除容器 docker-compose ps #作用也是查看容器，但是它只能查看docker-compose启动的容器，使用docker run启动的容器无法看到 docker-compose start docker-compose stop docker-compose restart docker-compose logs
[root@docker-server3 docker-compose]# docker-compose down
Stopping docker-compose_httpd-test-3_1 ... done Stopping docker-compose_httpd-test-2_1 ... done Stopping docker-compose_httpd-test_1 ... done Removing docker-compose_httpd-test-3_1 ... done Removing docker-compose_httpd-test-2_1 ... done Removing docker-compose_httpd-test_1 ... done Removing network docker-compose_default
[root@docker-server3 docker-compose]# docker-compose up -d

启动停止的操作
前面就是对docker-compose的一个简单介绍的操作，后续在仔细研究docker-compose的语法以及案例
