通过之前的示例，其实我们可以看到，所有服务的管理，都是依靠docker-compose.yml文件来实现的。那么我们接下来就详细说一说docker-compose.yml文件中的常用指令。
compose文件使用yml格式，docker规定了一些指令，使用它们可以去设置对应的东西，主要分为了四个区域：
官方网站：https://docs.docker.com/compose/
用于指定当前compose文件语法遵循哪个版本，下面这张表是不同的Compose文件版本兼容的Docker版本：
[root@docker-server3 docker-compose]# docker-compose version
docker-compose version 1.25.0, build 0a186604 docker-py version: 4.1.0 CPython version: 3.7.4 OpenSSL version: OpenSSL 1.1.0l 10 Sep 2019
这里的版本是这个指令的版本，上面的版本是语法的版本，语法不停的更新，version就是指定语法版本
也可以精确到小版本
将前面的版本修改为1，尝试
[root@docker-server3 docker-compose]# vi docker-compose.yml
version: ‘1‘ services: httpd-test: image: httpd:2.4 httpd-test-2: image: httpd:2.4 volumes: - "/data:/var/www/html" ports: - "80:80" httpd-test-3: image: httpd:2.4 volumes: - "/data:/usr/local/apache2/htdocs" ports: - "8080:80"
[root@docker-server3 docker-compose]# docker-compose stop
使用指令报版本错误
ERROR: Version in "./docker-compose.yml" is invalid. You might be seeing this error because you‘re using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1. For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/
定义 docker- compose管理的服务，包括服务的名称、使用的镜像、挂载的数据卷、所属的网络、依赖等等
上面的实例
[root@docker-server3 docker-compose]# vi docker-compose.yml
version: ‘3‘ services: #docker run -d --name docker-compose_httpd-test_1 httpd:2.4 httpd-test: image: httpd:2.4 #docker run -d --name docker-compose_httpd-test-2_1 -v /data:/var/www/html -p 80:80 httpd:2.4 httpd-test-2: image: httpd:2.4 volumes: - "/data:/var/www/html" ports: - "80:80" #docker run -d --name docker-compose_httpd-test-3_1 -v /data:/usr/local/apache2/htdocs:rw -p 8080:80 httpd:2.4 httpd-test-3: image: httpd:2.4 volumes: - "/data:/usr/local/apache2/htdocs:rw" ports: - "8080:80"
上面一共三个容器，使用dockers run运行就是
docker run -d --name docker-compose_httpd-test_1 httpd:2.4 docker run -d --name docker-compose_httpd-test-2_1 -v /data:/var/www/html -p 80:80 httpd:2.4 docker run -d --name docker-compose_httpd-test-3_1 -v /data:/usr/local/apache2/htdocs:rw -p 8080:80 httpd:2.4
第一行缩进就是容器的名字，但是在启动后，docker-compose会自动添加信息作为容器的名字
image：就是镜像的名字
容器在docker-compose都是后台运行的
自定义数据卷
下面的- 表示可以跟多个
version: ‘3‘ services: httpd-test-2: image: httpd:2.4 volumes: - "/data:/var/www/html" - "/etc/localtime:/etc/localtime" ports: - "80:80" - "2222:22"
docker命令：docker run -d --name docker-compose_httpd-test-2_1 -v /data:/var/www/html -v /etc/localtime:/etc/localtime -p 2222:22 -p 80:80 httpd:2.4
volumes，可以不指定挂载路径，则会把路径挂载在本地的默认路径下使用driver：local
相当于-e传参数
version: ‘3‘ services: httpd-test: image: httpd:2.4 httpd-test-2: image: httpd:2.4 volumes: - "/data:/var/www/html" - "/etc/localtime:/etc/localtime" ports: - "80:80" - "2222:22" httpd-test-3: image: httpd:2.4 volumes: - "/data:/usr/local/apache2/htdocs:rw" ports: - "8080:80" environment: index: "test"

网络决定了服务之间以及服务和外界之间如何去通信，在执行docker-compose up的时候，docker会默认创建一个默认网络，创建的服务也会默认的使用这个默认网络。服务和服务之间，可以使用服务的名字进行通信，也可以自己创建网络，并将服务加入到这个网络之中，这样服务之间可以相互通信，而外界不能够与这个网络中的服务通信，可以保持隔离性。
使用host网络

最初只有harbor.yml,install.sh,和prepare三个文件
修改harbar.yml文件，然后执行prepare，就会把所有的需要的文件放在common里面。同时生成一个docker-compose,yml文件
install.sh就是把docker-compose.yml文件启动起来
所以也可以不用instll.sh.直接启动
